Jan Molendijk PIDs in Europeana Webinar, 15 February 2013

Europeana and PIDs As an aggregator of aggregators, Europeana is hit hard by lack of PIDs Typically 3% of dead links –Temporary outages –Objects moved, URLs changed http 301 redirects not used very much Daily checks and feedback through

Our own Europeana IDs Hash based on dataset ID and object ID – D4D3B2808F4891C0205E7D41214C A5F108.html Heuristics to keep dataset ID constant Object ID comes from data provider, so is just as ‘persistent’ as the original Growing number of object IDs that are ‘official PIDs’

Advocacy Need for PIDs explained in handbooks and instructions for Data Providers We have to be agnostic as to which PID scheme is used Need for meta-resolver? –Not really: users of PIDs als give us good URIs

Europeana – How can we help Europeana is more than just ‘the office’ Network of >500 motivated individuals, 2200 Data Providers, Aggregators and projects So how can we help? –Should we perhaps assign PIDs and share with providers? –How can we improve advocacy?
