Confirm DFG subject taxonomy ontology is the correct choice
The thematic classification of resources in the KH via dcat:theme should follow the DFG subject areas classification. We want to reuse this in a semantic context, preferrably by reusing an existing rdf vocabulary/ ontology and not create by ourselves.
It seems like right now only 2 ontologies exist for semantically enabling the DFG subject areas:
None of them seem to be in wide use and both are lacking resolvable PURLs. Currently the 2. option is used, because it seems that the git repo is more update and being maintained. However, this needs to be confirmed.
