PIDfest 26

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.
