Hi, If we want to do some action cleaning I can mention that regarding the following one > ACTION: Antoine and Ed to add content to Primer about irreflexivity > [recorded in http://www.w3.org/2008/05/06-swd-minutes.html#action06] The section 2.3.1 of the Primer [1] will be added with the following proposal: > In a similar way, SKOS does not assume that hierarchical relations are > irreflexive by default. In most thesaurus design guidelines, it is > indeed prohibited to specify that a concept is broader than itself. > However, in specific cases beyond classical thesauri, some reflexive > skos:broader statements may occur. Consider the conversion of an > existing RDFS/OWL ontology into a SKOS concept scheme: in such a case, > it is legitimate that every rdfs:subClassOf statement will be > re-interpreted as a skos:broader one. However, rdfs:subClassOf is a > reflexive property, which means that for every class C, the statement > C rdfs:subClassOf C is true [OWL]! In this case every concept would > therefore have itself among its broader concepts. Cheers, Antoine [1] http://www.w3.org/TR/skos-primer/#sechierarchy
