Nary relations on the semantic web

New W3C Working draft: Defining N-ary Relations on the Semantic Web: Use With Individuals. "In Semantic Web languages, such as RDF and OWL, a property is a binary relation; that is, it links two individuals or an individual and a value. How do we represent relations among more than two individuals? How do we represent properties of a relation, such as our certainty about it, severity or strength of a relation, relevance of a relation, and so on? The document presents ontology patterns for representing n-ary relations and discusses what users must consider when choosing these patterns." Bernard Vatant has prepared a draft annex dealing with representation of n-ary relations in Topic Maps.
