9 years ago In BIBFRAME we seem to be headed in this direction (unofficially – please do not cite this elsewhere, for now).
Using classification as an example:
bf:Work bf:classfication http://id.loc.gov/authorities/classification/ML1015.K23.
<http://id.loc.gov/authorities/classification/ML1015.K23> a bf:Classification ;
a LccClass ;
rdf:value “ML1015.K23” ;
bf:assigner <http://id.loc.gov/vocabulary/organizations/dlc>.I think we should consider this for identifiers too.
Modsrdf:Resource modsrdf:identifier http://example.com/idenifiers/issn/1234567890.
<http://example.com/idenifiers/issn/1234567890> a modsrdf:Identifier;
a modsrdf:Issn;
rdf:value “1234567890” ;
bf:assigner <http://example.com/identifier/organizations/xyz>.

(http://www.loc.gov/standards/mods/modsrdf/primer.html#propertyTerm) Example: ModsResource12356 identifier:isbn ‘0-937383-18-X’ If the vocabulary for the identifier type is not known, it is treated in a manner similar to classification, as described in Type and Value Bound Together. " Here is an example that includes both: http://www.loc.gov/standards/mods/modsrdf/examples/0002.rdf
BIBFRAME created a number of subproperties: http://bibframe.org/vocab/identifier.html I remember there was a lot of discussion about this on the BIBFRAME list back in July.
One question about the MODS RDF example above. It treats an lccn differently than an OCLC identifier -- which makes me wonder how exactly is "known vocabulary" defined? Those listed on id.locgov?
Also, should we continue with the current approach going forward?
