Re: S36 implementation details

Dear Frederik,

It's mostly a timing issue.
At the time SKOS was made OWL2 property chains were still a fresh notion. We were aware of their development but it seemed a bit premature to base the SKOS standard on them. Hence we didn't consider using them.
As a matter of fact the official OWL specification of SKOS is still an OWL1 one.

Best,

Antoine

It appears in this comment <https://github.com/AKSW/Xturtle/blob/develop/vocabularies/xturtle.skos/skos.ttl#L180> and in S36 <https://www.w3.org/TR/skos-reference/#collections> of the reference document, but I’m not able to find its implementation.

Which has me wondering if a transitive property in place of rdf:rest positioned inside an owl:propertyChainAxiom — like so: ex:member owl:propertyChainAxiom (ex:rest ref:first) would achieve the desired effect.
