UMBEL Concept

UMBEL, short for Upper Mapping and Binding Exchange Layer, is a sub-set extraction of OpenCyc, providing the Cyc data in an RDF ontology based on SKOS, OWL and RDFS. Its purpose is to relate "Web content and data to a standard set of subject concepts [and] provide a fixed set of reference points in a global knowledge space. These subject concepts have defined relationships between them, and can act as binding or attachment points for any Web content or data."

UMBEL maintains its own Web site.
