There aren't. An ORCID ID is a unique opaque identifier for a person. The way it would be used in DSpace is to uniquely identify authors, contributors, etc. of an item. So the ID itself is metadata about the item (showing its relationship to a person), the same way that dc.contributor.author is, but it's a different type with different syntax and semantics. The ORCID organization holds *other* metadata which identifies an ORCID ID with a person, and DSpace's use of the ID would be a reference to external metadata about that person. The ID itself, when stored in DSpace, would not be "about" the person; it's an opaque token that someone could use to retrieve (from ORCID) information about the person, or simply to select a subset of holdings associated with a specific but unnamed person. It describes the item. (There has got to be a better way to say this. I did say I'm not really a metadata person.) > > I doubt, as you do, that DC has any place for ORCID IDs, which are > > unique identifiers with URL syntax. > > In that case, I'd suggest to add a new metadatafield dc.identifier.orcid. But I don't think DCMI defines such a type. So it shouldn't be shoved into the DC namespace. Doing that would lumber a DSpace instance with metadata which gives the appearance of being standardized but is globally uninterpretable. Conforming implementations of DC specifications should consider this type invalid and ignore it or flag an error. -- Mark H.
