XwkOnt¶
The Crosswalk of Foundational Ontologies
XwkOnt is an open reference project whose sole purpose is to build a concept-centric crosswalk across eight foundational (upper) ontologies.
XwkOnt is not another foundational ontology.
It documents, compares, and connects existing foundational ontologies.
