Hello all,

The Samvera MODS and RDF Descriptive Metadata Subgroup is pleased to announce that the initial draft of the MODS to RDF Mapping Guidelines [title?] is now available for review and comment:

[TK link to draft for comment]

This application profile provides recommendations for mapping MODS XML metadata for digital objects to RDF Linked Data classes and properties using a range of widely-adopted RDF namespaces.

The result of a 30-month collaborative process involving participants from more than a dozen academic and public libraries, this document includes a comprehensive mapping of MODS elements to RDF using real-world metadata use cases and hundreds of examples. A straightforward "direct" mapping (which does not require creating or maintaining local objects for concepts such as subjects, people, events, or places) and a more thorough "minted object" mapping are provided for most MODS elements.

In order to fully represent the scope of descriptive metadata for digital objects, the mappings include properties from vocabularies that have been extensively used in other Linked Data datasets, such as, Dublin Core, BIBFRAME, BIBO, RDA, FOAF, EDM, and LC Linked Data Service datasets, among others. Rather than pursuing a straight XML-to-RDF approach using the MODS RDF Ontology v.1 or proposing (yet another) new formal ontology, the re-use of these vocabularies provides greater value to records in a Linked Data context, and helps fill in the representational gaps found in many schemas.

Although this work was conducted under the umbrella of the Samvera digital repository framework, the mapping is system-agnostic and intended to be applicable in a wide range of contexts.

All comments and feedback are welcome. Comments can be added directly to the Google Doc or [TK some other means of feedback; somebody's personal email address?].

Thanks for your consideration!
