John Chodacki
John Chodacki is Director of the University of California Curation Center (UC3) at California Digital Library (CDL). As UC3 Director, John works across the UC campuses and the broader community to ensure that CDL’s digital curation services meet the emerging needs of the scholarly community – including digital preservation, persistent identifiers, data management, and data publishing. Prior to CDL, John oversaw product development activities at publishing organizations such as O’Reilly Media, Safari Books Online, and PLOS. He has served on the board and/or steering committees of DataCite, Crossref, FORCE11, ROR (Research Organization Registry), COUNTER, Collaborative Knowledge (Coko) Foundation, Open Citations, Metadata 20/20, Make Data Count (MDC), Collaborative Metadata Enrichment (COMET), RDA-US, and The Carpentries.
Sessions
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.
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.
