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