rdfs:comment "The openWEMI ontology provides a high-level framework for vocabularies related to creations, from abstract notions of a work to tangible items. The classes and properties defined by openWEMI are intentionally broad and unrestricted, allowing for implementing vocabularies to better describe their specific target creations through subclasses, subproperties and other alignments. openWEMI builds on the work done in the library community (FRBR) but with many fewer constraints, thus improving reuse for metadata communities."@en .
