Hi Giancarlo, Bernard Vatant and myself have developed the EUROVOC schema in attachment for the EU/OPOCE. The schema and the documentation are copyright of the EU as mentioned in the owl and html file. This schema models a thesaurus (EUROVOC) which has a top-level structure of domains/micro-thesauri further specialized in a concept hierarchy. All micro-thesauri and the complete thesaurus are modeled as skos:ConceptScheme. The domains that are regrouping micro-thesauri were modeled as a complementary class with dedicated properties between Domain and Micro-thesaurus. The concepts are modeled as skos:Concept. These concept belong to the EUROVOC thesaurus and to at least one micro-thesaurus. The html file gives an explanation. The owl file is owl-2. it imports the skos and skos-xl from the web. Extension classes and properties have additional comments in the owl. feel free to ask explanations when needed. Hope this helps.
