Because often within one "file" or contribution, or vocabulary, a set of related ConceptSchemes is described, we needed some grouping of Conceptschemes into groups. Especially when a repository starts to contain lots of vocabularies some subgrouping of ConceptSchemes is needed (:for retrieval. Of course a partially satisfying solution for us would be to say that a ConceptScheme is a "document" and therefore we could make the ConceptSchemes accessible through SKOS annotation using skos:subject of some SKOS hierarchy of ConceptSchemes. ). A specific SKOS standard solution could be useful. But Jakobs proposal seems to suggest that the group of ConceptSchemes is yet another ConceptScheme (iso-3166), itself containing no skos:Concepts, i.e. not exists X: X skos:inScheme iso-3166.
