NEPOMUK Contact Ontology (nco)
NEPOMUK Contact Ontology describes contact information, common in many places on the desktop. It evolved from the VCARD specification (RFC 2426) and has been inspired by the Vcard Ontology by Renato Ianella. The scope of NCO is much broader though. This document gives an overview of the classes, properties and intended use cases of the NCO ontology.
