Welcome to this forum for discussion of ARKs (Archival Resource Keys) and more general identifier issues, including scheme-agnostic resolvers (e.g.,
n2t.net), identifier inflections to access different aspects of an object via one identifier, and supporting protocols, metadata, and standards. There is also a French-language ARKs discussion forum at
