PID, identifier


This requires a resolving service’s URL to be added to the persistent identifier. (e.g. https://doi.org/10.18452/1503 or https://nbn-resol-ving.org/urn:nbn:de:kobv:11-100239432). As for the metadata export, see also Criterion 6 – Indexing and Inter-faces, section 2.6, Minimum Requirement M.6-6. The persistent identifier is made available in human-readable and machine-readable form on the website, and in machine-readable form via OAI (Dublin Core element identifier).
