Make resulting RDF graph valid (in respect to qSKOS) - View classes and concepts as different, but related ontologies.

[rue-a]

FromqSKOS GitHub Page:
"qSKOS(https://github.com/cmader/qSKOS) is a tool for finding quality issues in SKOS vocabularies. It can be used as command line tool or API. For release information please see the changelog."

A service to check a certain graph against the metrics of qSKOS is available at SKOS Play!

Current versions of exported graphs fail, with the issue being having disconnected clusters in the same SKOS Concept Scheme. These clusters are the harmonized concept and the harmonized classes, which are both part of the same concept scheme, but are not connected over SKOS properties (which is intended).

In my eyes, a reasonable way to fix this, would be to view the classes and concepts as two different, but related vocabularies, and accordingly provide two concept schemes.
