Explicitly stating the metadata author-agent using the Relation field sounds sane to me, though I'd suggest in this light that metadata authorship is important enough for validating metadata that it should have a field of its own, perhaps DC.MetadataAgent. Whether this actually contains information, or merely points to other information, is a point for debate. For decent quality verification of metadata authorship, the record for a particular metadata author-agent would contain links to all the metadata that this author-agent created. That, or we should have a standard means for recording digital signatures for authored metadata. So the DC.MetadataAgent could contain, say, the link to the author's record and a signature based on the rest of the metadata. I can tell you right now, it's less trouble to implement verification with signatures than cross-links. Using the DC.Relation of IsMetadataAuthorOf/HasMetadataAuthor is going to blow out your data storage. "Is MetadataAuthorOf" is one of those relations that can be explored by finding everything that a particular person is listed as being "HasMetadataAuthor". Unless you only write 500 metadata resources in your life, using two-way linkage is going to be very expensive, in terms of initial storage and continual updates when the location of a resource changes. You're going to need a fast RDBMS just to manage your "IsMetadataAuthorOf" table. If it's possible to keep a global directory of authors, then digital signatures on metadata would be a more sensible option, IMHO (because it means less work for the programmers, which means higher quality software).
