I have attached (below) an XML/RDF schema that Eric prepared for those
proposed MARC Relator terms (the original is still at
http://dublincore.org/2000/03/13-marcrel). In accordance with our
decision to move out of the directory tree of the DCMI registry all
XML/RDF schema files that have not been approved by the Usage Board,
this would presumably be moved elsewhere -- or we would decide that the
DC namespace URIs, which will probably end up starting with
http://purl.org/dc, resolve to something other than this directory
tree.
The model we are discussing implies that LC would make such a schema
available for us to point to and would maintain it over time. What
kind of statement would we as UB be making about those terms -- for
example, would we acknowledge the terms individually or as a whole
namespace? Could LC add terms or otherwise maintain that list without
seeking approval for every change, and would added terms automatically
be considered "recommended by DCMI UB"? Would LC need to acknowledge
the same sort of namespace policy we are discussing for DCMI (eg,
deprecating terms is okay, but they should never be removed; adding
terms is okay; changing definitions is okay within limits...)?
