PIDfest 26

TBD

When looking at the term ‘Persistent Identifier’ by itself, the focus is on the ability to enquire and identify entities, and to continue to do so over time. However, most of the value from using PIDs comes from the metadata that is available with the PID record. In this short presentation, we will not only explain how metadata registration enables understanding, but also discuss four different layers of enrichment, namely member updates, community feedback loops, matching, and third-party data sources. We aim to show that enrichment can strengthen the reliability of the scholarly record and build the Research Nexus. We hope that this will provide the community with more insight into ways to optimise the use of metadata and that the session will lead to a lively discussion on how we can improve metadata together.

We introduce new developments in documenting the historical funding activities of the German Research Foundation (DFG). The starting point is GEPRIS Historisch, a database released in 2020 for the DFG’s centenary that provides access to more than 50,000 research projects from around 13,000 scientists between 1920 and 1945. We discuss how this material can be enriched by linking it with external data sources, focusing on the use of PIDs. The dataset was published in 2025 on Zenodo as a scientific analysis dataset, enabling new forms of historical research.

We outline plans to extend the documentation of DFG funding history by closing the gap between 1945 and the start of the project database GEPRIS in 1999. We also present methodological approaches for large-scale PID assignment that enable the systematic linking of researchers.

In this session, you will learn how to implement PIDs practically as part of a major interoperability project, by taking a workflow-focused approach. You will gain insight into user research and design techniques to clarify requirements and facilitate alignment between collaborators, and discover how to approach PID workflows pragmatically to ensure implementability, maintainability and adoption.

This presentation provides an introduction to the use of Uniform Resource Names (URNs), specifically URN:NBNs, as persistent identifiers, using Finland as an example.

URN:NBN identifiers are currently in use in 13 European countries, with the national library providing services and coordination. However, as there is no organization overseeing the use of URNs on a global level, there used to be little international cooperation in this area, and the profile of URN:NBNs has remained relatively low. The situation has started to evolve with the publication of a URN:NBN landscape report (https://urn.fi/URN:NBN:fi-fe2024052134041) and the launch of the URN:NBN Network in 2024.

The National Library of Finland has been providing a national URN resolution service since 2007. The ease of implementation and cost-free nature of URNs has led to the wide adoption of URN-based persistent addresses in Finland.

What happens to research context when data gets published? Too often, the rich metadata from active research—protocols, collaborators, instruments, but also funding —gets "lost in translation" between lab notebooks and data repositories. Research Activity Identifiers (RAiDs) offer a way to keep that connection alive.

This session presents learnings from the US RAiD pilot program, bringing together two complementary perspectives: ResearchSpace, developers of the RSpace research data management platform, and the University of Texas at Austin's Texas Data Repository. Together, they explore how RAiD can thread through the research lifecycle—from active research documentation to data publication—creating durable, machine-readable connections in the PID graph.

You'll hear about integration patterns, metadata strategies for bi-directional linking, and practical approaches that minimize researcher burden while maximizing the metadata value of your repository deposits.

Your PID infrastructure almost certainly leaves grey literature behind. This matters more than you might think. Grey literature — reports, policy documents, intergovernmental assessments, technical publications — underpins the world's most consequential decisions, yet remains largely invisible to PID systems. Fewer than 5% of citations in the first six chapters of IPCC's AR6 reference grey literature, and 15% of those links are already broken. The IPCC confirms this wasn't deliberate: contributors simply found DOI-bearing content far easier to cite. There's a second problem. Tracking real-world research impact — in government, policy, and corporate settings — requires journal-to-grey-literature citation analysis. Without grey literature PIDs, that analysis is impossible at scale. In this session you will discover how Content Object Identifiers (COIs), deployed across Policy Commons and Applied Science Commons, are solving both problems. You will leave understanding why grey literature PIDs are no longer optional infrastructure.

In this session, you will learn about the Université Laval (UL) Library's experience being the first in Canada to integrate three PIDs (ROR IDs, ORCID IDs, and DOIs) to its institutional repository. Being an early Canadian adopter of the DSpace PID integrations, the Library faced many challenges. You will learn how the UL Library team worked with the community to improve the PID integrations and the impact it has had on its community. Attendees will leave with insights for navigating similar PID integration projects in their own contexts. They will also learn about the importance of those three PIDs in the context of institutional repositories.

It’s impossible to escape generative AI (genAI) in the modern research landscape; in fact, some of the very abstracts in the program may have been written by it! But for every time-saving benefit it has brought us, it has also exacerbated existing problems in publishing, like overburdening reproducibility mechanisms and boosting paper mills and fraud, as well as introducing new problems like publishing hallucinations and misinformation because authors might simply not have read what AI has produced before submitting.

Thankfully, a good solution framework already exists: persistent identifiers! Come join us, the Knowledge Exchange PIDs4AI working group – a collaboration of six European research infrastructure providers and research supporting organisations – and learn how PIDs could address the proliferation of genAI outputs and their opaque provenance with a value based approach that focuses on: transparency over detection, infrastructure over policy, normalisation over stigma, evolution over perfection and coordination over fragmentation.

Do you struggle to implement persistent identifiers (PIDs) in regions with limited infrastructure or financial constraints? While 11 million researchers have ORCID iDs, institutional integration and collaboration with trust markers remain uneven, particularly in the Global South. In this session, you will discover how ORCID works to overcome systemic barriers and implement successful, community-led solutions that promote Open Science and FAIR principles.
You will explore real-world strategies for navigating technical gaps, fee structures, and linguistic hurdles that often exclude communities in Latin America, Asia and Africa.
By the end of this session, you will:

• Have resources to enhance a "community of practice" in your country or region.
• Discover how to utilise the Membership Equity Program (MEP) and strategic grants to jumpstart integrations and community building in low and lower-middle-income countries.
• Identify how you can help adapt global models to be inclusive and equitable for underrepresented regions.

Do you ever feel like your research data is drifting further away from the physical objects that inspired it? Keeping knowledge connected to baseline data from specimens and samples is a massive hurdle, but it is exactly what you will learn to master in this session.
You will explore how the Distributed System of Scientific Collections (DiSSCo) uses PIDs in the form of FAIR Digital Object compliant DOIs to create "Digital Twins" for billions of biological and geological specimens. We’ll dive straight into how you can confront the barriers of technical debt and institutional silos. You will gain a clear understanding of how FAIR Digital Objects turn static records into living, linked data and discover practical strategies to ensure PID infrastructure remains sustainable for the long haul.
Don't let your data become a dead end - come find out how to keep the world’s scientific heritage permanently connected.

In this presentation, you will see how new citation tools leverage established PID and DOI systems, to deliver structured, machine‑actionable attribution and provenance across interconnected research objects.

This presentation overviews how comprehensive use of PIDS helps enable RSpace to orchestrate FAIR workflows across research infrastructures. RSpace is used to collect and manage data, and document experiments, in the active research phase of the research lifecycle. It is integrated with 20+ other research tools used in the planning, active and sharing/archiving phases of the research lifecycle. RSpace incorporates support for traditional PIDS – ORCIDS and RORS, enabling association of research outputs with individuals and organisations. Over the past two years support has been added for IGSN IDs, pidinsts and RAiDs, so persistent identification of samples, instruments and projects can be linked with individual and organisational attribution in the context of active experimental work. Moreover, we are working with developers of other categories of tools, in particular DMP tools and repositories, to ensure that association of PIDS with the research outputs is consistently maintained as data passes between tools.

In this talk you will learn about the sea of different software identifiers that exist, and where they are used. If you study this topic, you may feel you are drowning. Which identifier seems most natural for you to use probably depends on your role, whether you are a publisher, librarian, software developer, software user, informatics researcher, etc. Your discipline may also matter, as there are different identifiers in use in different fields, such as life sciences, astronomy, math, etc. We'll talk about this and how all of these identifiers are related. Hopefully you will be able to help, including using persistent identifiers (PIDs) as much as possible. By the end of the talk, perhaps you will no longer be drowning but will be swimming comfortably.

The Dutch National pilot within the OSTrails project explores how machine actionable data management plans (maDMPs) can support researchers and research institutions in keeping knowledge connected. In the presentation we discuss the three pillars in this European project: planning (through DMPs), tracking (through Scientific Knowledge Graphs), and assessing (through FAIR assessment). In our national pilot we support the planning and tracking phases through a RAiD supported workflow. RAiD, the research activity identifier, acts as a PID for projects but at the same time as an envelope that links to other PIDs such as funding (GrantID), project members (ORCIDs), and research outputs (DOIs). By integrating maDMPs with RAiD, we aim to make open research information an integral part of the research process, with an emphasis on the start-up phase.

Are your repository's PID integrations doing the bare minimum? This session draws on production experience with DSpace, the world's most widely deployed open-source repository platform, to show what ORCID, ROR, and DOI can actually deliver when treated as infrastructure rather than metadata fields.

Most repository managers have all three identifiers in place but have never seen a complete picture of what they unlock day to day. You'll discover how DOIs become a live metadata pipeline via Crossref and OpenAlex, how ORCID powers full researcher entity creation rather than just name disambiguation, how ROR finally brings order to years of affiliation chaos, and how PID-based matching pulls in external data from Scopus and Web of Science without manual intervention.

The central argument: this is the path from a standard publication repository to a functioning CRIS - and you're already holding the keys.

Must adopting global standards mean sacrificing local identity? This session deconstructs the myth of the "one-size-fits-all" approach to Persistent Identifiers (PIDs). Through real-world case studies, we will demonstrate how integrating ORCID with national and specialist ID systems reduces administrative burden, eliminates "identifier fatigue" for researchers, and unlocks deeper collaborative insights. Attendees will walk away with a practical roadmap to transform fragmented data into a unified, interoperable global dataset.

Do you rely on ORCID, DOI or ROR to connect research information across systems, but still encounter missing affiliations and incomplete metadata?

In this session you will discover results from the Dutch Open Research Information Monitor, a national initiative that analyses how persistent identifiers are actually used across the research information ecosystem.

The monitor compares metadata across CRIS systems, OpenAlex, OpenAIRE and Crossref to identify gaps in PID coverage, metadata completeness and open licensing.
Using real use cases from universities and research funders, the monitor reveals where PIDs work well, where connections break, and what interventions could improve the ecosystem.

You will gain practical insights into:

• how PID adoption can be monitored across infrastructures
• where gaps appear in ORCID, ROR usage
• which interventions can strengthen connected research information

Do your researchers struggle with complex metadata schemas, PID types or scheme-URIs when submitting metadata? With ELMO, the new web editor from GFZ Data Services, they can simply fill in an easy-to-use online form, similar to Google Forms, and generate rich, FAIR, descriptive metadata for data publications at the same time.
In this talk, you will learn about:
How the functionalities of ELMO, specifically ORCID preloading, ROR autocompletion and guided controlled vocabularies help minimize errors and curation effort
How 'PID magic' happens in the background, with automatic recognition of DOIs, IGSNs and ARKs as related identifiers
How ELMO makes PID use a natural part of metadata entry and delivering valid DataCite 4.7 XML
Your takeaway: a concrete example of a user-centred metadata tool that is already in daily use at GFZ Data Services, providing researchers with real added value through the use of PIDs.

In this session you'll learn how and why Stanford University is integrating more PIDs throughout its research infrastructure. You'll learn about the rationale for the paths we've chosen and the benefits we've seen from these projects, and we'll discuss the challenges we've encountered and the work we have yet to do. You'll hear about three case studies utilizing three different PIDs: ORCID iDs, DOIs, and the newest PID -- BIBFRAME URIs via Blue Core.

Implementing persistent identifiers (PIDs) involves more than assigning hyperlinks to records. It also supports the broader goal of keeping knowledge connected across systems, workflows, and users. This requires a structured approach that takes into account existing identifier systems, technical infrastructure, and long-term governance. This session presents a practical case based on the introduction of ARK identifiers at the Royal Library of Belgium (KBR). It outlines the mapping of the existing identifier landscape, how implementation choices can be evaluated, and how migration from non-persistent identifiers can be managed. Attention is also given to maintaining stable references, signalling changes in records for humans and machines, and aligning identifiers with both digital systems and physical workflows to ensure that knowledge remains connected and accessible over time. The session offers a practice-oriented perspective on developing a PID strategy that supports sustainability, access, and institutional responsibilities over time.

In 2024, Australia launched its National Persistent Identifier (PID) Strategy to accelerate research quality, efficiency, and impact through the universal use of connected PIDs. To measure this progress, the Australian Research Data Commons (ARDC) commissioned Digital Science to develop a national benchmarking framework. This presentation shares key findings from the resulting Australian National PID Benchmarking Toolkit, which reveals a "mixed score card" for the nation's research ecosystem.

While Australia demonstrates world-leading ORCID adoption for publications, significant gaps remain. Australian researchers trail their European peers in data citation practices , and PID use for non-traditional research outputs (NTROs) is lacking. We will discuss the report's 23 recommendations , including mandatory ORCID implementation, new dissertation policies, and treating institutions as publishers. Finally, we will introduce the open-source toolkit—comprising analysis and runnable code —as a scalable model for other nations to track their PID strategies.

Are you curious about how France is shaping its national strategy for persistent identifiers (PIDs) to streamline data management and enhance research visibility? Do you want to understand how ORCID, the National Directory of Research Structures (RNeST), and the exploration of PIDs for research instruments work together to address challenges in traceability, interoperability, and administrative burden reduction?

When the National PID Centre at the National Library of Technology launched in January 2023, awareness of PIDs in the Czech Republic was still relatively low, and many relevant stakeholders across the research community did not yet recognize their practical value. Looking back at the three years of raising awareness and supporting the adoption of PIDs in the Czech research environment, you can learn what worked in the development of centralized PID support services. More importantly, you might benefit from the challenges the Czech PID Centre has encountered and, in some cases, continues to deal with. While some of these are specific to the Czech context, key lessons learned from, e.g, operating the national ORCID and DOI consortia along with insights from conducting a cost-benefit analysis as well as a national PID adoption survey can offer valuable inspiration - or a cautionary tale - applicable to your local context.

RAiD (Research Activity ID) is a persistent identifier for research projects, linking outputs, funding, and personnel. With humble beginnings in Australia, RAiD is moving quickly into its next phase of governance and operation at global scale.

This presentation introduces the PID community to the Global RAiD Operating Alliance, a strategic partnership between the RAiD Registration Authority (Australian Research Data Commons - ARDC) and the Registration Agencies (RAs) to scale and operate RAiD internationally. Partners include SURF Netherlands, the San Diego Supercomputer Center (SDSC), and the Digital Research Alliance of Canada.

Members of the RAiD Operating Alliance, launched earlier in 2026, will discuss how they collaborate to guide and grow the RAiD system globally. They will detail how they work together to meet the needs of RAiD users and their plans for the future.

Globally adopted persistent identifier infrastructures such as Crossref, DataCite, and the Research Organization Registry (ROR) are critical to a connected research ecosystem. However, sustaining these shared services requires more than technical standards. It depends on clear operational models, shared principles, and coordinated and strategic efforts to leverage, connect, and build upon existing solutions.

This presentation focuses on the practical realities of sustaining open research infrastructure. Drawing on experience from Crossref, DataCite and ROR, we highlight how community governance, transparent operations, and funding models support long-term resilience,

argue for strengthening and connecting existing infrastructure, and share lessons on how organizations can work together to build a more coherent, sustainable ecosystem that supports global research.

Do you want to know if your institution gets open, reusable metadata — including PIDs like ORCID and ROR — from transformative agreements?

In this session, you’ll discover how we ran a parallel analysis of openly available transformative agreements listed in the ESAC registry to inventorize conditions for open metadata in publisher contracts, in an initiative connected to the Barcelona Declaration/OA2020 and OA Datenpraxis.

You’ll learn about:

• existing gaps in contracts: e.g., permission for full text but not metadata reuse
• missing commitments of PID (ORCID, ROR, Funder ID) use and provision
• how metadata provision differs across consortia: to Crossref, library systems and discovery tools
• real-world data: e.g., ROR are rarely submitted to Crossref

We share our reusable analysis method so you can audit your own contracts, push for stronger open metadata clauses or contribute to this collectively organized analysis for publisher contracts in your country.

The PIDs4AI group at Knowledge Exchange believes PIDs are the solution for addressing AI-slop. We presented our vision in a previous session but we’ve hardly got all the answers. It’s time for you to step into the arena and help us figure out how to wrangle this horse! Join us for a quick recap of our presentation (for those of you who couldn’t make it) followed by a debate over the most controversial parts of AI and how we can use PIDs to mitigate the stampede it’s currently running through the research landscape. We want to hear your opinions and build a coalition of PID-enthusiasts whether you’re a junior rider or seasoned champion!

As data volumes and complexity grow the question of how to scale Persistent Identifier (PID) systems becomes increasingly important. In practice, data is often organized in hierarchies - from collections to datasets to individual files - raising a key challenge: Which level of detail truly benefits users whilst keeping the systems operational?

This session invites participants to share real-world use cases, challenges, and approaches to PID assignment across different domains. Depending on the context, PIDs at the collection or publication level may be sufficient for discovery and citation, while more granular identifiers are required for reproducibility, automated workflows, and machine actionability. However, increased granularity introduces overhead and complexity, potentially leading to unsustainable proliferation of identifiers.

We aim to bring together diverse perspectives from different stakeholders to explore how decisions about PID granularity are made in practice, and how to balance the trade-off between too many and too few PIDs.

The ISSN International Centre recently launched a new portal offering enhanced services and tools for accessing and exploring the ISSN Register. This session will present these new functionalities and demonstrate how they improve discovery, navigation, and use of ISSN data for the community.
The presentation will also introduce ISSN-H, a new identifier defined in the revised ISO 3297:2022 standard. ISSN-H is designed to link serial publications that have undergone title changes and therefore received multiple ISSNs over time. By grouping these related resources under a single identifier, ISSN-H enables the identification of families of serial publications.
We will explain the principles guiding ISSN-H assignments and illustrate how this identifier can simplify identification and management of serials for libraries, publishers, and metadata users. The session will also situate ISSN-H within the broader persistent identifier (PID) ecosystem.

Persistent Identifiers for scholarly work have been around for more than 20 years and are quite crucial in enhancing the discoverability, credibility, and quality assurance of research out comes and their attribution. Persistence can be defined as the ability of an identifier to resist change over time. Where does this resilience to change come from, is it a function of the organisations that have stewardship of the PID or is it technology that underpins the identifier or is it something else?

If these are questions you have been asking yourself, this session is for you as we will be discussing what makes PIDs persistent and resilient to change.

What are the catalysts for membership growth in PID communities? Are you engaging with a new or emerging group of stakeholders that are still learning about PIDs? Speakers from Canada and the United States will discuss how national government policies on research integrity and security, organizational Open Access initiatives, and other open science efforts have provided opportunities to expand PID community engagement and adoption from early adopters (like libraries and publishers) to new stakeholders learning about PIDs (like research administrators and funders). After a brief presentation, participants in this session will engage in small group discussion to identify opportunities to increase PID awareness and adoption, and share ideas on engaging new stakeholders. The session will conclude with collective reflections, offering practical insights into promoting PID adoption and strengthening global research communities.

DataCite consortia provide access to DataCite services to organizations within their region or subject-based interest group. DataCite Consortium Leads have a lot of leeway to determine how consortia operate. What kinds of organizations are eligible to participate? How is the consortium funded? What kind of support does the consortium lead provide and how? In this Birds of a Feather session, representatives from existing or prospective Consortium Lead organizations will compare notes on how they think about these and any other questions of consortium management. Participants will have space to discuss any tricky problems they face, share success stories, and understand how DataCite consortia vary around the world. DataCite strives to foster venues for consortia to engage with each other, and this session will provide an important opportunity for consortium leads to share their points of view and strengthen a community of practice in person.

As PIDs become essential infrastructure for open research, funder compliance, and scholarly discovery, shared standards are more important than ever. In this session, you will learn how a National Information Standards Organization working group is turning community best practices into a consensus U.S. standard designed for global interoperability, for which many key systems are already largely compliant. This session offers a practical look at the core attributes of robust PIDs and PID systems—uniqueness, persistence, resolution, metadata, interoperability, governance, sustainability, security, and integrity—and the objective criteria behind them. You’ll get insight into the standards development process, leave with a clearer understanding of how these characteristics balance moving the field forward with real-world implementation, and learn how this emerging standard can help PID providers and users alike evaluate, strengthen, and future-proof this critical research infrastructure.

PRSM is a knowledge graph connecting publications, repositories, people, and institutions into 28+ million relationships. It exists because persistent identifiers exist. DOIs, ORCIDs, ROR IDs, and package registries made it possible to link data across OpenAlex, GitHub, and ecosyste.ms into something no single system could produce alone: full research impact analysis across publications and code, ecosystem health scoring, champions discovery, and dependency chains traced to compiled binaries.

As AI agents begin generating research artifacts at machine speed, persistent identifiers become even more valuable. Every synthetic dataset, automated analysis, and machine-written codebase needs provenance, attribution, and traceability.

This talk utilizes a live portfolio analysis to demonstrate the power of today's PID infrastructure, explore why identifiers become even more essential as AI-generated artifacts enter the research ecosystem, and discuss what's needed for identifier infrastructure to scale to trillions of generative artifacts.

This Birds‑of‑a‑Feather session examines how persistent identifiers (PIDs), in particular  people identifiers such as ORCID, can enhance trust, accountability, and interoperability in scholarly communication by enabling robust researcher identity verification.
As fraudulent submissions rise, STM’s Researcher Identity Verification Framework highlights the importance of proving both individual identity and academic participation, requiring a network of underlying PIDs, metadata, and linkages.

The discussion addresses how verified affiliations, academic contributions, and institutional identity providers can anchor scalable verification, linking researchers to their roles and outputs. A key theme is the propagation of trust signals across infrastructures like ORCID and Crossref, improving accountability and reducing fraud.

The session also acknowledges the need for anonymity or pseudonymity in legitimate contexts, emphasising a flexible PID ecosystem. Participants are invited to share challenges, including global inclusivity and early‑career researcher issues, with the aim of defining actionable steps for advancing PID‑enabled verification.

Are you involved in or assisting researchers with either making datasets produced in HPC environments available for reuse or trying to find the data you need for your work and finding it utterly cumbersome? Have you ever wondered about how AI applications can best find the training data required for a specific task across infrastructural boundaries? Indeed, in many domains, data are created at large, distributed HPC centers but are not operationally assigned globally resolvable PIDs at the point of production, making it hard to identify, track, and reuse these datasets across infrastructures.

In this BoF, you will discuss how PIDs could be integrated directly into HPC workflows at simulation runtime, explore current technical ideas and challenges, and discuss what would be needed to make data practically immediately usable across federated HPC systems. The focus is on practical questions around data access, metadata, provenance, and interoperability.

You've assigned PIDs to your datasets, your people, your publications. But where did that data actually come from? The data acquisition layer, the instruments, sensors, and control software that generate raw measurements, is almost always a blind spot in PID infrastructure. Open frameworks like PyLabRobot are tackling this from the software side, building the driver layer where instrument identity and configuration can finally be captured and stamped onto the data it produces. Come explore why DAQs are a missing link in connected knowledge, where the real barriers are, vendor lock-in, no open drivers, no persistent identity, no metadata that travels with the data, and what PID-connected instrumentation could actually look like. Leave with a clearer sense of what it would take to get there, and who else is working on the same problem.

For data providers and data users there is increasing interest in using large scale snapshots of entire datasources. For data providers this can relieve the stress and cost of running APIs. For users it allows for new kinds of analysis, creating global benchmarks and identifying gaps. PIDs are at the centre of these analyses, allowing us to link large datasources together reliably. ORION-DBs is an effort to make data dumps more usable by exploiting the capability of Google BigQuery. Setting up this federated set of cloud data resources we have identified patterns in which datasets are easy to ingest, which are easy to use and how they can be combined. In this BoF session we focus on a facilitated discussion of what the optimum data snapshot looks like in format, structure, regularity, locations and how these can help (or hinder) the ability of users to fully exploit these datasets.

Should publishers of research outputs, awards, and other entities register DOIs with DataCite or Crossref? These registration agencies have their roots in different use cases for different entities - Crossref for journal publications, DataCite for datasets - but their capabilities and focuses increasingly overlap. Today, DataCite and Crossref both: operate globally, support identifying and describing a wide variety of resources (journals/articles, books/chapters, datasets, dissertations, grants/awards, peer reviews, preprints, reports, and standards), and support connection metadata to other kinds of PIDs. As communities develop National PID Strategies, it is becoming difficult to differentiate between DataCite and Crossref; what kind of grounded advice can strategies offer their communities? In this BoF session, you will be invited to present your perspective on this question, contribute to a shared international conversation about registering DOIs, and provide feedback about how DataCite and Crossref might distinguish themselves from one another.

Chile has no funder mandate requiring persistent identifiers. Adoption is happening anyway, driven by an intermediary institution rather than by top-down regulation. Data Observatory, a public-private-academic foundation, leads Chile's DataCite consortium. Its early members are not only universities: the Library of the National Congress now assigns DOIs to legislative and parliamentary documents, extending persistent identification beyond research data into the public record itself.
This session traces that path: how a national FAIR data strategy, a shared consortium, a national CODATA committee and a regional alliance (SURDATA) were assembled without a mandate and without the funding assumptions the global PID infrastructure takes for granted. We discuss what worked, what did not, and what the international PID community may be missing when it designs for contexts that already have mandates, budgets and institutional density.

In 2023 eLife launched a ‘Publish, Review, Curate’ (PRC) model of publishing which emphasised the publication of preprints, preprint review, and ‘post-publication’ curation. In this session you will discover how PIDs can create a public record connecting the revisions of a paper with public peer reviews, metadata (e.g. funding), and related research outputs (data and code). You’ll explore the practical considerations when registering metadata for ‘new’ types of research output that don’t neatly map to existing content-based schemas in scholarly infrastructure, and hear how we navigated the tension between best practice and author requirements.

After this session, you will understand:

• How to architect a PID strategy that transparently links preprints, article versions, peer reviews, data and software.
• The challenges that accompany mapping new or alternative models of publishing to the existing scholarly infrastructure.

In short the storyline would focus on what challenges lie ahead for PIDs to keep knowledge connected. In a world where geopolitical turmoil puts strain on knowledge to be shared openly and neutral, PIDs could ba a backbone to trust. But in order to do so (and save the world ) the PID community would need to reflect, adapt and rethink the ways of working.

Scientific experimental and computational workflows typically involve multiple steps to generate a final result. Recording all steps therefore requires a structured digital system with several hierarchical levels. In our repository, these steps are integrated into parent records containing RO-Crates that provide a detailed description of the workflow, along with links to granular data and metadata. Each parent record is assigned a DOI PID, while individual records describing specific steps and associated data are assigned ePIC PIDs. This approach enables both the complete workflow and its individual components to be accessed, cited, and reused independently.

At Naturalis Biodiversity Center, we deal with a wide variety of research activities: analyses of genomic sequences, studies of physical collection specimens, and images from biomonitoring cameras, to name a few. In turn, those activities produce all sorts of data and involve different people, equipment, software tools, possibly from different projects and institutions. We started exploring how Research Activity Identifiers (RAiDs) can help in linking all those disparate elements together in a pilot study, and we're taking those insights along as we continue our developments around PIDs. So... are you wondering how to implement RAiDs across complex, scary, real-world scenarios? Are you also confused about what qualifies as a "research activity" and what doesn't? And would you like to know how RAiDs come into a picture full of sample IDs, project numbers, and specimen labels flying around? Then this lighting talk is for you!

Persistent identifiers (PIDs) are essential for connecting the global research ecosystem, yet adoption often depends less on technical capability and more on whether stakeholders understand their value. Researchers, librarians, infrastructure providers, funders, and policymakers all interact with PIDs in different ways and are motivated by different incentives.

This interactive workshop introduces a persona-based approach to designing effective PID engagement strategies. After a short introduction exploring challenges and opportunities in PID adoption, participants will collaboratively develop stakeholder personas and identify motivations, barriers, and messaging strategies that resonate with them.

Through a structured group activity, participants will create “persona cards” representing real actors in the research ecosystem and design tailored PID messaging and value propositions for each.

In the AI era, the explosive growth of science and technology resources and interdisciplinary convergence have posed unprecedented challenges to knowledge infrastructure. Ensuring that massive science and technology resources are Findable, Accessible, Interoperable, and Reusable (FAIR principles) on a global scale has become a central issue in the development of open science. As the "digital ID card" for digital objects, Persistent Identifiers (PIDs) serve as the critical technical foundation for connecting fragmented knowledge and building a trustworthy research ecosystem.
In this workshop focuses on the opportunities and challenges of PID infrastructure in the AI era, exploring how persistent identifiers empower artificial intelligence to understand and connect scientific knowledge. Representatives from DataCite, South China Botanical Garden, Chinese National Space Data Center and Africa PID Alliance are invited to share practices across different identifier systems and regions

The Research Activity Identifier (RAiD), a PID for Projects, was originally developed in Australia; other countries are now also beginning to implement and test national and regional RAiD services concretely: Canada, the Netherlands, and the US. This panel will provide updates from these three pilots, led by SURF in the Netherlands, Lyrasis and the San Diego Supercomputer Center in the United States, and the Digital Research Alliance of Canada and Canadian Research Knowledge Network in Canada. Panelists will share the current status of their RAiD pilots, including an overview of stakeholders involved, prominent use cases or workflows of focus, and plans for next steps.

As the understanding of PIDs has grown – the community – institutions, funders, policy-makers – are looking beyond identifying objects, to realise the systemic value of a connected PID ecosystem. The lion's share of the value of DOIs, ORCIDs, ROR IDs, etc. lies in the relationship metadata illuminating how the identified objects relate to each other. The possibilities to make connections between entities across the system, especially where information about the relationships is included and open, promise opportunities for greater insights, evaluation, and so - more strategic decisions and better informed policy.

In this session, speakers will report recent developments in improving metadata capture and availability across the scholarly ecosystem and open the floor for participants' input on opportunities to further boost the coverage of open metadata for research objects.

Have you ever suggested an addition or update to ROR and wondered how the proposed changes got turned into an actual ROR record? Or have you wanted to suggest a change but weren’t sure how to proceed? If you’ve ever been curious to learn more about how the ROR registry is maintained, this interactive workshop will take you inside the entire process and give you a newfound appreciation for the humans, machines, and mechanisms that make it all possible.

What are your favorite graphics or images demonstrating the value of PIDs? Have you created or found one that you love, or do you wish you knew how to create or find one? Let’s get together and share our favorite PID visuals, try generating some with AI tools or with pens and our own brain power, and explore what the ideal PID image would be. Does it communicate through metaphor, as in pictures of interconnected roads, plumbing, or natural waterways? Is it a network visualization generated from real data? Does it chart figures such as potential savings or increase in usage over time? Is it a PowerPoint slide with organizational logos on it connected by lines? In this workshop, you'll imagine, create, and share images that convey why persistent identifiers are so important, creating a public image library that everyone in the PID community can use.

Questionable research practices (QRPs), such as inappropriate authorship acknowledgement, lack of transparency in data reporting, and problems in verifying research outputs, bearing significant challenges to research integrity and scholarly communication. In recent years, Persistent Identifiers (PIDs) have emerged as an important digital infrastructure for improving transparency, accountability, and traceability in research ecosystems. Systems such as ORCID, Crossref, and DataCite allow researchers, publications, datasets, and institutions to be uniquely and persistently identified across digital platforms. By connecting research outputs with their creators and associated metadata, PIDs help reduce ambiguity in authorship, strengthen citation practices, and support responsible research assessment. In this research study, it is identified how PIDs can contribute to reducing questionable research practices by enhancing transparency in scholarly communication. Further, it reveals how the adoption of PIDs can support research integrity initiatives, mainly in developing research systems where monitoring and tracking research outputs remain challenging.

B2INST is a Persistent Identifier (PID) service that is designed to persistently register, describe and reference instruments and equipment. By uniquely identifying instruments, describing them with metadata and ensuring they are reliably citable, B2INST aims to address gaps in research data management and enhance the reproducibility of scientific results.

B2INST provides unique, stable, globally resolvable identifiers for scientific instruments and research equipment. This allows researchers to unambiguously reference and cite the instruments used in their research, thereby promoting transparency, reproducibility, and collaboration. Assigning a persistent identifier to each instrument can also support tracking of instrument usage.

The metadata management uses the RDA-endorsed PIDINST metadata schema to capture details such as the instrument's name, model, owner and manufacturer. This provides the basis for standardised information exchange.

Additionally, the community features allow research communities to extend metadata schemas, implement moderation workflows, and apply their own branding.

Physical samples are foundational evidence in heritage science but often lack persistent links to digital research records. The Heritage Sample Register provides a technical preview of a registry designed for sample level identification. It implements the International Generic Sample Number (IGSN) to provide physical specimens with globally unique identifiers. Through the IGSN and DataCite partnership, these samples are integrated into the DOI ecosystem and discoverable via DataCite Commons. The technical architecture follows FAIR Digital Object principles, utilising Cordra as a reference repository with metadata validated through JSON Schemas. Parallel to this infrastructure, the initiative is developing a sustainable community model to support the register as a permanent service. This effort aims to create a stable identification layer that connects physical archives with the broader digital research ecosystem. By the time of this conference, the pilot service will be operational, demonstrating the practical application of persistent identifiers for heterogeneous heritage materials.

The DOI registration agency DataCite maintains the largest collection of metadata about research data and is uniquely positioned to facilitate activities like data discovery and scientometric research. However, previous research has highlighted that DataCite metadata is often incomplete.
In this session, you will learn whether this problem can be addressed by improving metadata flows from disciplinary research data repositories to DataCite through optimized schema crosswalks.

Do you need a simple way to manage FAIR data while still keeping rich metadata, provenance, and persistent identifiers?

In our light talk you will discover Metafiles, a lightweight approach designed for research and digitalization projects where many datasets and files require structured metadata and clear relationships. The system combines ARK persistent identifiers, structured XML metadata files, and a consistent RDF representation of metadata and stored efficiently in a relational database.

Instead of relying on large infrastructures, this approach focuses on practical workflows researchers can integrate directly into their projects. Metadata can be shared across related activities, dependencies between datasets, scripts, and results can be captured through machine-readable provenance, and responsibilities for data management can be organized hierarchically across teams.

After this light talk you will better understand how persistent identifiers, provenance, and shared metadata support scalable and reproducible research workflows while remaining simple enough for everyday research use.

This year, a new player to support the use and implementation of PIDs in Austria has been introduced: the PID.at Competence Center. In this lightning talk, you will learn about the center’s goals, action plan and first achievements. Join us as the PID.at Competence Center takes its next steps and discover fresh opportunities for collaboration.

As gold models of Open Access rise in popularity, Institutional Repositories (IRs) have emerged as strong, reliable paths towards openness. Despite this, there has been a lack of uniformity in how institutions of higher education promote and embed PIDs in their IRs. This talk will address how one institution, the American University in Cairo (AUC), has begun to explore the utilization of PIDs in its’ IR. AUC’s IR, the Knowledge Fountain, will be compared with IRs around the globe to investigate how the case for PIDs can be built in a manner that is locally informed, while also maintaining abreast of changing international standards. This session will act as a case study and provide a potential framework to better understand how players across diverse fields of academia may play a role in expanding access and transparency in research with the use of PIDs.

Recording institutional Open Science outputs is challenging particularly when organisations collect information across multiple departments and sites. Uptake of persistent identifiers (PIDs) for various outputs across people, places, and funders offers a solution. To foster an interconnected Open Science landscape, Europe PMC has embarked on two pilot projects with the European Molecular Biology Laboratory and SciLifeLab to incorporate ROR IDs into the literature records. Many institutions generate and maintain publication output lists to measure their positive impact on science and society. Using human-curated metadata to link ROR IDs to publications in Europe PMC creates more open, reliable, and efficient analysis, monitoring and funder compliance checks, and demonstrates the value of upstream PID collection. In this talk, we present the pilot workflows, technical integration, and lessons learned to encourage wider adoption and reduce manual institutional workflows.

If you are part of an emerging NREN or research community struggling with low visibility, limited infrastructure, and fragmented research outputs, this session will show you how to move from isolation to global integration using persistent identifiers (PIDs).
In many emerging National Research and Education Networks (NRENs), research outputs exist but lack persistent identifiers, interoperability, and structured integration into global infrastructures. Without DOIs, ORCID adoption, institutional identifiers, and connected repositories, visibility, citation tracking, and impact measurement remain limited.
This session demonstrates how you can build a sustainable PID culture within an emerging NREN, even in environments with constrained resources and evolving digital policies. You will explore practical strategies for phased PID adoption, governance alignment, and community engagement that support long-term sustainability.
You will leave with actionable insights to strengthen research visibility, enhance institutional participation, and position your NREN as an active contributor to the global PID ecosystem.

Do you struggle to reproduce analyses months later or reuse someone else’s workflow? This session shows you how to make your research executable, reusable, and FAIR-compliant using persistent Jupyter notebook environments. You will discover how the ICOS Carbon Portal provides access to persistently identified datasets while supporting complete analytical workflows.
Jupyter notebooks combine code, documentation, and results, but rapidly changing software dependencies often prevent reliable reproduction. You will see how capturing notebooks, code, and dependencies in archived Docker images allows you to preserve the full execution environment and rerun analyses on demand.
By the end, you will understand how to publish executable workflows with persistent identifiers, preserve computational environments, and reduce reproducibility challenges—helping you keep your research accessible and trustworthy over time.

Scientific instruments are essential research assets, yet they remain largely invisible in the persistent identifier (PID) ecosystem. "Materials Instruments" addresses this gap by developing an open infrastructure that improves the discoverability, interoperability, and reuse of scientific instruments in materials science while strengthening FAIR research infrastructures.

"Materials Instruments" is a new service of the FID Materials Science (Specialised Information Service Materials Science) aiming at the community of researchers in the materials sciences.. The project allowed collection and distribution of instrument metadata from heterogeneous sources and prepares them for integration into the PID ecosystem. A central component is the planned assignment of DOIs to instrument records, enabling reliable citation and cross-linking between instruments, publications, datasets, and research institutions. This talk presents practical implementation steps and lessons learned, including challenges related to metadata aggregation, licensing, governance, and community adoption when integrating instruments into the broader PID ecosystem.

Do you struggle with creating complete, high-quality DataCite metadata or reusing existing records efficiently? In this session, you will discover the updated DataCite Metadata Generator developed by LMU Munich, designed to simplify and enhance your metadata workflows.

You will learn how the tool enables you to create, upload, validate, and improve metadata in both XML and JSON formats. It also enriches metadata quality by automatically integrating PIDs via APIs such as ORCID and ROR.

You will also see how the generator is designed to be easily updated when new DataCite schema versions are released, ensuring long-term usability. You will explore how this open-source solution can be integrated into your own institutional workflows and adapted to specific needs. By the end of the session, you will better understand how to streamline metadata creation while improving consistency and reuse.

Many publishers turn to the ROR API to match text-based affiliations to persistent identifiers (PIDs). This tool typically yields a matching percentage of just 52% to 57%, if one restricts oneself to reliable outcomes. In this session, you will discover further possibilities for matching, such as Human Intelligence Tasks, Machine Learning, and Vector Search. This is based on concrete experiences from a project carried out at a medium-sized German science and medical publisher. An intriguing question to which we ourselves do not yet have an answer: will artificial intelligence ultimately remove the necessity for a human in the loop?

RAiD (Research Activity Identifier) is a next-generation, ISO standard, persistent identifier designed to formally link all components of a research project - people, organisations, funding, instruments, and data - throughout the research lifecycle.

This presentation will detail how RAiD strengthens the Persistent Identifier (PID) ecosystem by acting as a central hub. Specifically, we will explore RAiD’s purpose-built metadata schema, which is optimised to capture the complex relationships inherent in research activities, moving beyond simple one-to-one connections.

We will also demonstrate how the RAiD API enables machine-to-machine retrieval of these rich connection graphs, transforming how PIDs are leveraged for attribution, reporting, and provenance tracking, thereby increasing the value and utility of existing PID investments for the community.

How can you use data to better understand and improve ORCID adoption in your research environment?
In this lightning talk, you will discover how the Czech National ORCID Consortium works with real data to support ORCID adoption and improve researcher data quality. You will see how working with data can help identify challenges in researcher identification and improve data quality, illustrated through an example such as detection and monitoring of potential duplicate researcher records over time based on data from the national research information system (IS VaVaI).
You will also learn how working with different data sources can provide further insights into ORCID adoption and data quality, depending on context and available data.
This session will give you a practical example of how data-driven approaches can support communication with institutions and policymakers and help improve the quality and consistency of researcher data.

In this presentation, you will hear about the process of collecting use cases and developing best practices for PIDs for Instruments and Facilities in the Australian context.

If you are interested in learning more about how facilities and instruments can be identified in a National context, then this session is for you. Attendees will gain an insight into how the i4iOZ (identifiers for instruments, Australasia) Community of Practice have developed best‑practice guidelines for facility and instrument identification across the country.

These best practices are informed by the Australian National PID Strategy and international standards such as PIDINST and the work of the FAIR Facilities and Instruments Network. This session will also provide real-world use cases to support effective PID adoption from organisations implementing these approaches.

If you’re building a persistent identifier program from the ground up, you may be wondering what real indicators of success look like. In this session, you’ll learn how to launch and scale a PIDs initiative in a decentralized environment. Using Waterloo’s pilot as a case study, you’ll see how targeted affiliation assertions for PhD students and postdocs led to stronger trust in graduate research impact, streamlined reporting, and created a growing campus‑wide momentum. You’ll take away practical success metrics, communication strategies, partnership‑building approaches, and scalable next steps to help your PID work keep knowledge connected across people and systems.

Are you interested in learning how to contribute to the DataCite Metadata Schema? DataCite provides open infrastructure for research organizations to contribute key metadata about their research outputs, resources, and activities as part of DOI registration, enabling citation, discovery, and reuse. We are continuously evolving the DataCite Metadata Schema to align with community needs—and we can’t do it without you. In this lightning talk, you’ll learn how you can help shape the DataCite Metadata Schema: how to share your ideas with us, where you can discuss proposals, and how to stay up to date with all the latest schema developments.

ARK (Archival Resource Key) identifiers are decentralized, non-paywalled PIDs.
Not everyone knows that ARKs (like DOIs, Handles, URNs, and PURLs) were
introduced 25 years ago for research and scholarship, and now appear in the
Data Citation Index, Wikipedia, ORCiD profiles, etc.

Research funders are under growing pressure to demonstrate the impact and reach of their portfolios, but doing so requires being able to connect grants to outputs reliably and at scale. Persistent identifiers are the connective tissue that makes this possible: Grant IDs, ORCIDs, RORs, and output IDs allow funders to link funded projects to who does the work, at which institution, and what it produces. In this workshop, representatives from ZonMw and NWO share their practical experiences implementing PID strategies, including what was difficult, what worked as expected, and what surprised them. This is followed by an OpenAlex demonstration that provides context on how open reporting systems use PIDs (or work around their absence) to create funder-level insights. The session is grounded in real implementation and invites participants to reflect on the funder's role in the broader PID ecosystem.

The Digital Object Container Identifier (DOCiD), developed by the Africa PID Alliance, creates a federated framework that transforms fragmented research identifiers into interoperable, machine-actionable digital objects. By integrating ORCID, ROR, Ringgold, CSTR, DataCite, Crossref, Handle, and RAiD, DOCiD aggregates researchers, institutions, outputs, projects, and infrastructure into a single structured container aligned with FAIR Digital Object principles. This session showcases DOCiD’s architecture, highlighting layered PID integration and real-world applications in research, repositories, and international collaborations. Special focus is on Indigenous Knowledge and Cultural Heritage systems, where DOCiD ensures ethical governance, provenance tracking, and CARE-compliant stewardship. Participants will learn how DOCiD strengthens global interoperability, supports research infrastructures, and elevates Africa’s role in research innovation. The session features expert PID presentations and a live demonstration, providing practical insights into PID federation, containerization, and the transformation of identifiers into socially impactful, FAIR+CARE-compliant research objects.

This workshop will help develop the PID matrix created for the Canadian PID strategy into a tool that can be used by the PID community globally. After a brief history of why and how the matrix was developed, and an overview of the current version, the presenters will use interactive tools to ask participants to share their thoughts on the core elements, and on any new categories or elements needed. The rest of the workshop will be spent brainstorming next steps for the matrix, through a series of exercises.

Modern science uses a wide variety of instrumentation as a core part of the research cycle. globally, and persistently identifying instruments has significant benefits for research, such as reusability, interoperability and transparency of scientific outputs, and have also many use cases in operational, funding, and administrative aspects of research processes. This workshop concentrates on discussing technical aspects of how to persistently identify instruments and on the societal and administrative aspects of practically implementing instrument identification in research organisations.
The workshop builds on the outputs of the Persistent Identification of Instruments Working Group in the Research Data Alliance, including the development and ongoing maintenance of the PIDINST metadata schema, and the outputs and plans of the TDCC-NES FAIR4instruments workshop on the practical implementation of instrument identification in the Netherlands.

Effective disaster detection and response depends on integrating heterogeneous signals across meteorological, geospatial, epidemiological, infrastructure, and community domains, yet these systems remain siloed, lacking a persistent, machine-actionable way to navigate the relationships among them. This workshop explores how persistent identifiers (PIDs) and a connected PID graph can serve as the connective tissue for a complex adaptive disaster management system. Drawing on the CADEM framework's emphasis on non-linear, multi-actor, feedback-driven response, and on Fakhruddin's work on FAIR data policy for disaster risk, we ask: what would it take to make cross-domain disaster data not just FAIR, but actionable at speed? Applying CODATA's Cross-Domain Interoperability Framework (CDIF), participants will work collaboratively to map PID requirements across disaster management phases, identify the governance and technical barriers to a functional DRR PID graph, and propose a practical implementation roadmap aligned with the Sendai Framework.

Current PID systems, especially DOI, still depend on a central authority that could disappear, change its policies, or simply go offline. We present a non-blockchain-dependent, truly decentralised Persistent Identifier architecture that eliminates single points of failure without the energy costs or governance complexity of distributed ledger systems. It is reached through a DHT-based, cryptographically verifiable mesh of nodes, realms, and providers that can mint, resolve, and version PIDs across scientific research, industrial automation, and open-data ecosystems. The architecture supports FAIR principles through persistent, machine-actionable resolution paths, while data loss resistance is achieved through mandatory replication across providers and a Git-like sectioned hash tree that the integrity. The presentation describes a realm-based multi-lookup mechanism by which the same PID could be resolved from multiple contexts. We kindly invite all the participants to discuss the ideation of the implementation and the addressed challenges.

Have you ever wondered why an article is open access, even when you already know it is? Current metadata usually won’t tell you whether it’s covered by a transformative agreement, a consortium deal, or another funding model. Finding this information takes time, and even when it appears somewhere in the text, it’s rarely in a reusable format. To change this, a persistent identifier (PID) for open access agreements is being introduced, supported by a central registry. With it, you can immediately see why an article is open access and explore the context behind different agreements. The registry is integrated into the Electronic Journals Library (EZB), ensuring long‑term stability and easy reuse. And with the openCost schema, you can even add these PIDs to your repository to improve transparency. Curious to learn more? Dive into the EZB’s new tools and explore how they work.

Commercial publishers usually do not include some metadata when they register DOIs.
This talk want to show you a project devoted to measure this issue, detailing which open sources and techniques will be used to collect data and presenting some first results

Do your faculty enter incorrect DOIs into research information portals? Do you want to ensure the PIDs your faculty are entering into ORCID are correct? Learn about how FSU built a system using open data to validate faculty DOIs before they are moved from FEAS (Faculty Expertise and Advancement System) to ORCID.

You will learn how this system classifies DOI errors, how this system uses open data to validate DOI entries, why it is important to validate DOIs, how a similar system could be built at your institution, and how this system can be leveraged to support faculty in the future.

While the share of digital only objects in library holdings and scientific output is growing rapidly, the comparative short life span of both digital resources and the tools needed to access them make them vulnerable to damage and loss. Geopolitical developments have been adding to this vulnerability, putting political and financial pressure on institutions providing important public data bases. Digital preservation counters these inherent and external tendencies to dissolution by securely archiving resources, keeping their contents both intact and readable. Yet to retrieve resources from possibly dark archives when they are lost from public data bases we need findable metadata telling us where to look. This talk gives a short oversight on which kind of PID metadata could be especially useful for documenting digital preservation and aid recovery, and how this information can be or is already stored with different PID metadata setups.

Get to know the Digital Ccompetnece Centre for Practice Oriented Research's e-learning 'Getting Started with PIDs'! In this session:
you will get to know the interactive content of the e-learning,
gather ideas on how to implement the e-learning within your own institution,
at the same time, you will boost your knowledge of PIDs,
and contribute ideas on how to make the e-learning even better.

The rapid expansion of artificial intelligence (AI), Internet of Things (IoT), and data-intensive research has significantly increased the volume and complexity of scholarly data. Managing this growing digital knowledge ecosystem requires reliable mechanisms to uniquely identify and connect research entities across platforms. PIDs have emerged as a foundational component of modern research infrastructure, enabling the consistent identification of researchers, publications, datasets, software, institutions, and other research artifacts. Within the framework of the FAIR (Findable, Accessible, Interoperable, Reusable) principles, PIDs play a critical role in ensuring that research outputs remain discoverable, interoperable, and machine-actionable. Global PID systems such as ORCID, Crossref, DataCite, and the Research Organization Registry support trustworthy scholarly communication by linking research information across digital environments. For developing nations, adopting PID frameworks offers a strategic pathway to enhance research visibility, strengthen data interoperability, and integrate national research outputs into global knowledge networks in AI-driven scientific landscape.

PIDs connect everything together, which requires significant collaboration across all research sectors and stakeholders. Ultimately, local resources and policies are required for a collaborative response to PIDs, which typically takes place at the regional or national levels - even though PIDs are essentially international endeavors. Without these national approaches, PIDs remain difficult to implement and scattershot in their adoption. As countries continue to develop and implement National PID Strategies at varying speeds and with varying levels of sophistication and community buy-in, this session offers a timely opportunity to reassess the global landscape and reflect on collective progress. There are many drivers of PID adoption and implementation globally - from the integration of PIDs into funder systems to the availability of resources in a given language, as just a couple of endless possible examples. Each national strategy approaches drivers differently, depending on their context and resources - how does your region approach PIDs?

Funders can drive change in the research sector by establishing funding requirements that influence institutions and individuals. Current practices in Australian mean that the metadata available about research practice is often limited, may not be available at all, and may be of a low quality or missing key information. In this presentation you will find out about a range of initiatives led by the Australian Research Council to both use PIDs and to encourage the uptake of PIDs by the Australian research sector in alignment with Australia’s National PID Strategy.

Self Addressing Identifiers (SAIDs) provide a decentralized, content based method for verifying the integrity of structured data and metadata. By hashing an object’s content and embedding the result back into the object, SAIDs allow anyone to independently confirm authenticity without relying on a central authority. This session introduces the principles behind SAIDs, explains how they complement traditional identifiers like DOIs, and highlights their advantages for workflows requiring immediate, verifiable integrity checks. Real world adoption at Agri Food Data Canada (ADC) demonstrates how SAIDs can be embedded into schema writing tools, enabling each schema version to carry its own built in proof of integrity. The session also covers the newly registered urn:said namespace at IANA, which supports interoperability across systems. Participants will learn how to generate SAIDs, integrate them into infrastructures, and apply them to enhance trustworthy, standards based metadata practices.

Whether you produce, maintain, analyze, or integrate DataCite DOI metadata, you have probably experienced challenges with keeping it up to date, navigating gaps and inconsistencies in metadata properties and practices, or curating metadata for specific applications. While DataCite DOIs enable connectivity and interoperability, enhancing data quality and efficiencies across systems and workflows, the metadata associated with them still requires ongoing maintenance that can only be performed by original creators or in isolated applications.

A collaboration between DataCite and COMET is advancing innovative technical and community-based approaches to improving PID metadata for everyone and at scale, currently focused on DataCite DOIs but broadly applicable across the ecosystem.

If you’ve ever wished for a better way to improve DataCite metadata or PID metadata in general, this session will present a concrete path forward, showing examples of metadata enrichment processes and tools developed through the collaboration.

Do you want to understand how interoperable metadata and PIDs can increase impact of research infrastructures and help researchers find the right services for their needs? In this presentation you will discover how Finnish organisations have developed and how they utilise interoperable metadata to describe their research infrastructures and services for research.

You will hear about our approach to define and categorise research infrastructures and services, and how we link them to each other and other research activities to build a view of the national landscape. You will learn how PIDs help to keep service information up-to-date, consistent and accessible through machine readable APIs and user friendly interfaces. You also get examples of use cases which support findability, accessibility and impact of research infrastructures and services.

Do you sometimes feel like PID adoption should be easier than it actually is? You are not alone. In this session you will hear a first-hand account of what it really takes to embed persistent identifiers across a large, heterogeneous research infrastructure – Germany's National Research Data Infrastructure (NFDI), spanning dozens of institutions and disciplines.

PIDs are widely recognised as a key enabler for FAIR RDM. But between that recognition and actual adoption lies a significant implementation gap: administrative hurdles, domain-specific vocabularies, fragmented technical systems, and a mismatch between emerging topic hype and foundational groundwork. Not all efforts succeed, and not all stakeholders are receptive – though occasionally an intervention makes an unexpected difference.

After this session, you will recognise the most common barriers to PID adoption in complex multi-stakeholder environments, have a realistic picture of implementation timelines, and understand why frustration tolerance is a genuine project competency.

The Helmholtz Metadata Collaboration is developing a harmonized FAIR metadata space across the Helmholtz data ecosystem. A key element is the broad implementation of Persistent Identifiers (PIDs) such as ROR, ORCID, IGSN, PIDINST, DataCite DOI, and Crossref DOI to reduce metadata redundancy, improve interoperability, and support machine-actionability. However, PID adoption alone is insufficient. FAIR implementation also requires clear workflows for capturing PID metadata, defined responsibilities for PID registration and maintenance, and suitable tools and services integrated into the research data ecosystem. This presentation introduces the building blocks of our Road-to-FAIR strategy, including the overall vision and priority tasks for improving interoperability and reusability. In particular, we will reconsider traditional repository-centered approaches and demonstrate how a broader range of actors in research can contribute to PID-based research data management across Helmholtz Earth and Environment centres.

For more than a decade, the ePIC (Persistent Identifier Consortium for eResearch) initiative has been delivering a robust PID infrastructure across the globe. In that time, it has expanded both in terms of members and the suite of standardised services offered.

Come see if ePIC has something to offer you as a user, project collaborator, service provider, or perhaps even as consortium member!

Is your PID strategy getting lost in fragmented systems, inconsistent metadata, and unclear responsibilities? If this sounds familiar, then see how the project PID Network Germany tackles these hurdles with its national PID roadmap. In this presentation, you will learn how structural, technical, and governance-related barriers can be systematically addressed.
You will gain insights into a nationwide survey of research and cultural institutions, thematic workshops, PID provider interviews, pilot implementations of metadata guidelines, and the development of a national PID Monitor. Together, these qualitative and quantitative approaches revealed key obstacles in interoperability, automation, metadata quality, and sustainable governance and served as the basis for developing the PID roadmap.
You will gain evidence-based insights into how community engagement, monitoring, and practical testing create a comprehensive picture of the national PID landscape. You will also learn about persisting challenges and concrete starting points for coordinated and sustainable national PID implementation.

In this presentation, you will be introduced to the concept of Persistent Identifier (PID) graph and how PIDs can provide a reliable means of presenting, analysing, and understanding research activity. Relationships between PIDs like ORCID, DOI, ROR etc offer important information about researchers, their works and their collaborations. Understanding how these identifiers connect and relate to one another, you will gain a clearer view of collaboration patterns as reflected by scholarly publications. Using a publicly available script, the presentation will also demonstrate how data derived from institutional publication records can be used to collect and visualise collaboration data. Through animated visualisations you will be able to see how researchers collaborate across national and international borders.

Do you want to ensure that persistent identifiers are not just assigned, but actually used across the research lifecycle?
In this session, you will see how automated Key Resource Tables embed RRIDs directly into preprints and how these identifiers propagate into platforms like Europe PMC and evolve in journal articles.
You will discover how RRIDs are detected, suggested, and structured at the preprint stage, and how they change - or persist - between preprints and published versions. This reveals how early PID integration influences downstream data quality, discoverability, and reuse.

Amid debates about the credibility of academia - sparked by scandals involving fake conferences – we proposed creating an infrastructure to improve transparency around academic events. The aim was to establish a registry that records conferences, workshops, and similar formats using structured metadata and assigns DOIs, enabling clear identification, citation, linking, and long-term discoverability. The ConfIDent project launched in 2020 during the COVID-19 pandemic, when widespread cancellations, postponements, and rapid transitions to online meetings exposed weaknesses in existing event documentation. While these developments highlighted the need for reliable records that preserve event information as details change over time, early implementation revealed limitations in the chosen technical platform, including usability challenges, limited interoperability, and reliance on manual data entry, which slowed adoption. Drawing on these challenging lessons, but ongoing community support, we are now preparing a redesigned infrastructure to relaunch the registry sustainably.

How can you keep track of scientific prizes in a consistent and reusable way? In this session, you will discover the Open Registry for Awards and Prizes (ORAP) and how it helps you structure award information with persistent identifiers.

You will get an overview of the ORAP metadata schema and the use of identifiers such as ORAP-PRIZE-ID, Wikidata and future ROR IDs. You will also learn how awards are collected, reported and curated through a growing community effort.

A short live demo shows you how you can use or contribute to the registry.

Messy, inconsistent metadata is one of the biggest blockers to data interoperability— and it usually happens because metadata is an afterthought, often added long after the data was created. In this session, you'll see how PID4NFDI, TS4NFDI, and the RSpace research data management platform establish a practical interoperability layer that puts interoperable metadata right at the point of data creation. Using embedded terminology widgets and cross-schema mappings, researchers can capture DataCite-aligned metadata without ever leaving their lab notebook. The result: cleaner data, less manual clean-up, a reusable model that can extend to other tools and services, and ultimately data and PIDs with metadata that can easily be transformed into other formats.

During a large author affiliation data coding project of academic publications in Flanders, it was discovered that one third of the mentioned organizations were not included in the global reference database, the Research Organization Registry (ROR). The coding could only be completed by adding new organizations to a local copy of ROR. This tool evolved into a new instrument: the Flemish Organization Registry, creating additional unique identification codes for all organizations involved in research in Flanders and enabling the connection of publication, project and government databases on an organizational level. This presentation zooms in on this project, demonstrating how to extend a global (organization) database with a local dimension.

SURF has been providing IT support to research and academia since 1971 and has been providing PIDs since 2012. Over the last 14 years we have expanded our services across many domains, set up PID consortiums, helped draft national and international policy, helped develop PID selection and service validation tools, developed new PID services and are even hosting this conference! Let our services team take you through SURF’s journey and present what went well, what you might want to imitate, and what you definitely shouldn’t do! We want to inspire you about what an organisation can do and the impact you can have as well as pass on our wisdom to save you some time and a lot of frustration (while maybe sharing a couple of laughs)!

Persistent Identifiers (PIDs) are critical infrastructure for open science, yet their adoption across Africa remains uneven. In this presentation you will discover the challenges to PID adoption in Ghanaian Higher Education Institutions (HEI), offering insights for keeping knowledge connected. Drawing on interviews, policy analysis, and institutional case studies, we identify interoperability gaps, limited awareness, cost constraints, and fragmented governance/policies as key barriers. Legacy systems and inconsistent metadata practices further impede integration with global PID ecosystems. Despite these constraints, library-led initiatives, and researcher champions demonstrate scalable pathways forward. We propose actionable recommendations: coordinated policy frameworks, sustainable funding models, capacity building, and regional collaboration to align with initiatives like ORCID, ROR, and Crossref. By strengthening PID infrastructure, Ghanaian institutions can enhance research visibility, trust, and, advancing open science across Africa. This study highlights implications for PIDfest stakeholders seeking inclusive, interoperable knowledge systems that transcend institutional and continental boundaries for impact.

From its origins as the International Geo Sample Number over two decades ago, IGSN has evolved into a widely recognised persistent identifier for physical objects. Now known as the International Generic Sample Number, it assigns unique, persistent identifiers to physical samples across disciplines—from geoscience to archaeology and materials science. Managed by IGSN e.V. and strengthened through a strategic partnership with DataCite, IGSN has grown rapidly, surpassing 14.8 million registered samples by February 2026.

Today, IGSN is evolving to meet modern research needs. It will integrate into the global PID Graph, linking with identifiers like ORCID and ROR to enhance data connectivity and machine readability. At the same time, efforts to align IGSN with international standards and ontologies are improving interoperability across disciplines. Together, these advances position IGSN as a vital backbone for FAIR, connected, and future-ready scientific data ecosystems worldwide.

Using an existing, established PID system, a library consortium and government bodies are working together to create open data that can be attributed and which is linked and future-proof.
Two organisation from different disciplines have joined forces to enhance messy metadata into clean, reliable and connected data. Rather than dealing with variations like abbreviations, renamings, or typos, a single persistent identifier links datasets across data portals and over time. Replacing free text with GND URIs transforms open governmental metadata into real Linked Open Data — machine-actionable, traceable, and interoperable.
This high-level view is all about how different fields can work together to break down walls between people's ways of thinking. This is a real-life example of what works, what breaks systems, and the common pitfalls of public-sector cooperations.

If you replace all add-ons, sensors and modules on an EM microscope, is it still the same microscope? In this short talk, find out how we approach identification and traceability of scientific research equipment with FAST.

FAST is a web application for facility access and management, used by the EXCITE2 network to provide access to European research infrastructure, with a database of facilities, equipment and metadata identified using standard approaches like ORCID and PID.

This presents both an opportunity and a challenge: linking data publications back to the equipment used to produce them is only reliable if you can account for how that instrument has changed over time.

With FAST, we place equipment in time using an audit trail and date markers, pinpointing instrument attributes at any given moment. We'll discuss current progress, open questions, and what we hope to learn at PIDfest.

What are the benefits of using ISNI? How can this PID serve as a bridge identifier across sectors? And how can the use of ISNIs be extended at the national level? In this session, you will hear about the outcomes of our ISNI projects (2022–2025) and the results of the broad implementation of ISNI (International Standard Name Identifier) within the cultural sector and copyright management organisations in Finland. You will also see how the National Library of Finland (NLF) has led the coordination of ISNI projects and helped establish common practices among organisations. You will then discover how ISNI has been adopted in practice, including its integration into systems used by CMOs, museums and archives. The implementation has improved contributor’s data quality, interoperability and the consistency of metadata across organisations. In addition, you will hear about the NLF’s long-term vision for building a national ISNI ecosystem.

The Inter-university Consortium for Political and Social Research (ICPSR) is a membership-based organization that holds over 20,000 social science research data collections. To demonstrate the value of consortium membership, ICPSR must show member institutions evidence that their faculty and students are using, sharing, and publishing with data held at ICPSR. This presentation will highlight two projects at ICPSR that employ Research Organization Registry (ROR) IDs to draw connections between ICPSR data, the individuals that collect and use it, and their affiliation with ICPSR member organizations. One project aims to enhance metadata on principal investigators (PIs) of ICPSR data collections with ROR IDs. The other uses open bibliographic data to connect citations in ICPSR’s Bibliography of Data-related Literature to ICPSR member institutions. Both projects enable ICPSR to share information with members about how their faculty and students are using ICPSR data and platforms.

PIDs are increasingly important for repository workflows. Primary challenges for PID integration into open-source repository platforms include the ability to coordinate many moving pieces globally and identifying who might be responsible for moving any given development forward. In this session, you will learn how PIDs can be used in repository platforms, and a case study example for how PID advocacy work is moving forward for DSpace, an open source, community-driven repository software used by thousands of organizations across the globe.

Persistent Identifiers (PIDs) play a vital role in enhancing research security by enabling transparent, accurate, and interoperable tracking of research activities, affiliations, funding, and outputs. This presentation will explore how PIDs—such as ORCID iDs for researchers, ROR IDs for institutions, DOIs for publications and datasets, and grant identifiers—can help uncover risks related to undisclosed foreign affiliations, collaborations, and misattributed funding. PIDs support automated data validation, improving the integrity of researcher profiles, and facilitating cross-system compliance checks. PIDs are becoming essential tools for institutions and funding agencies to uphold the security and trustworthiness of the research ecosystem. In this session, we will explain the different persistent identifiers used in research, how they are used, and the level of adoption of PIDs worldwide. We will focus on the impact they have on research security workflows.

Connecting digital objects across the data repository landscape is critical for ensuring that open data are discovered and reused. Global adoption of common PIDs across repositories facilitates broad cross-repository discoverability, enables impact assessment and researcher credit, and supports compliance monitoring by funders and institutions. The NIH Generalist Repository Ecosystem Initiative brings seven generalist repositories together - working in a “coopetition” model - with a key objective to connect digital objects by enhancing dataset metadata quality, completeness, and consistency. Over the past 4 years GREI repositories have developed and implemented a common metadata recommendation that relies heavily on PIDs including DataCite DOIs, ORCID, and ROR. This presentation will showcase examples of GREI repository PID implementation, use cases, and repository best practices, as well as the impact of PID-based collaborations with DataCite, ROR, and NLM, and the value of common PIDs for author, affiliation, and funding metadata in better connecting data repositories.

If you’ve ever struggled to keep track of physical samples or to link them clearly to your research data, you’re not alone. Physical samples - whether geological cores, environmental specimens, or engineered materials - are essential to many research projects, yet they are often difficult to document, trace, and connect to the digital information that gives them meaning.
The International Generic Sample Number (IGSN) helps solve this by giving each physical sample a unique, persistent identifier that makes it easier to register, cite, and follow throughout its lifecycle.
In this session you will learn how 4TU.ResearchData is implementing IGSN as a new service within its research data infrastructure. You will learn why this service is being introduced, how it is being built, and how it will help you manage, share, and cite physical samples more effectively - strengthening the connection between your physical and digital research outputs.

Are your researchers expecting DOIs from your institutional research repository while it still relies on Handles?

This session offers a practical account of implementing automated DOI registration in TSpace, the University of Toronto’s institutional repository. You will learn how the University of Toronto Libraries is responding to the growing expectation that repository outputs participate fully in the global persistent identifier infrastructure.

Research articles still lack a common way to keep a stable identifier while also supporting precise citation of specific versions. Too often, platforms either overwrite an article so the reference remains stable or mint a new PID for every update, even when that adds cost, citation ambiguity, and metadata overhead. In this session you will see how the revised NISO Journal Article Versions (JAV) recommendations introduce semantic versioning as a clearer alternative to article overwrites or to minting yet another PID. You will learn how semantic versioning can identify the exact version used, when it can work better than assigning another PID, and where a new PID still makes sense. You will also see how this approach affects citations, publisher policies, preprint workflows, and the display of an article's version history.

From metadata to memes, governance to global collaboration, Suze’s closing keynote will celebrate the people, conversations, and connections that keep knowledge connected.
