Hello all,

The Samvera MODS and RDF Descriptive Metadata Subgroup is pleased to announce that our MODS to RDF Mapping Recommendations (v.1.0) are now available:

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 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.

Rather than pursuing a straight XML-to-RDF approach using a single vocabulary or proposing (yet another) new formal ontology, the mappings include properties from a plethora of existing vocabularies that are already extensively used, in order to provide greater value to records in a Linked Data context.

A straightforward "direct" mapping (which does not require creating local objects for concepts such as subjects, people, or places) and a more thorough "minted object" mapping are provided.

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.

The group would also like to express gratitude for all feedback received from the community; many suggestions submitted during the previous review phase have been incorporated into the recommendations.
