The Metadata Object Description Schema (MODS) Editorial Committee announced the posting of a draft MODS/RDF ontology. MODS, a descriptive metadata schema that is loosely based on MARC, is widely used to describe objects in libraries, archives, and museums. The new MODS/RDF ontology promises to usher MODS (and bibliographic data) into the realm of linked data. The MODS namespace has been under development for some time. The timing of the release of the MODS/RDF draft seems to be in response to the recent launch of BIBFRAME.org.
The MODS/RDF ontology homepage includes links to a primer, the MODS/RDF namespace document, and examples of MODS/RDF records. For those wanting to test drive the transformation of MODS/XML files to MODS/RDF, there is a stylesheet available as well.
The MODS Editorial Committee welcomes feedback on the draft ontology via the MODS listserv, where a number of MODS implementers have already commented on the draft.
MADS: Successful Linked Data Implementation
