UMBEL – Reference Concept Ontology and Vocabulary 1.0 has been released!
From the website:
This is the official Web site for the UMBEL Vocabulary and Reference Concept Ontology (namespace: umbel). UMBEL is the Upper Mapping and Binding Exchange Layer, designed to help content interoperate on the Web.
UMBEL provides two valuable functions:
- First, it is a vocabulary for the construction of concept-based domain ontologies, designed to act as references for the linking and mapping of external content, and
- Second, it is its own broad, general reference structure of 28,000 concepts, which provides a scaffolding to orient other datasets and domain vocabularies.
The mappings in Annex F: Mapping with UMBL are with owl:sameAs and umbel:isLike.
I would prefer more specific reasons for mapping. Particular given the varying use of owl:sameAs. Could mean just about anything.
Still, this is a valuable data set, although I would use it for mappings with more specific reasoning disclosed as part of the mapping.
PS: It has a really cool logo!
