The SKOS Core Guide includes reference to rules: http://www.w3.org/TR/swbp-skos-core-guide/#secaboutrules [[ Inference rules are part of SKOS Core. Inference rules are described in prose, and where appropriate are expressed using the Jena 2 rule syntax [Jena Inference], or as RDF statements using the OWL vocabulary [OWL]. Inference rules appear in boxes such as: An example rule. (?x ex:p ?y) -> (?x ex:q ?y) prefix ex: <http://www.example.com/eg#> ]] I can see what's going on here, but it makes me a little uncomfortable. If the SKOS recommendation is to make use of additional infrastructure, shouldn't this be couched in terms of a standards (e.g. RIF when it appears) rather than referring to some particular implementation (Jena rules)? Is there going to be some notion of comformance? For example, does this mean that I *cannot* provide a SKOS implementation without having some RDF repository that implements the rules -- and in that vein, what are the precise intended semantics of these rules?
