Removal of inverse properties

[jakubklimek]

Problem statement DCAT 3 has a policy on usage of inverse properties, where the inverse properties may be used only in addition to the primary ones. In DCAT-AP 3.0, this was reflected by removal of the inverse properties from the profile. GeoDCAT-AP 2.0.0 includes the following inverse properties:

• dct:isVersionOf, which was to be replaced with dcat:isVersionOf following the alignment with DCAT 3 and DCAT-AP 3.0, which is an inverse property
• foaf:isPrimaryTopicOf is used in several examples. This may be to improve readability compared to the usage of foaf:primaryTopic, but may also be confusing and encourage usage of just the inverse property.

Proposal Follow the approach of DCAT-AP 3.0 and remove inverse properties from GeoDCAT-AP. Specifically:

• deprecate dct:isVersionOf in favor of the new dcat:hasVersion (dct:hasVersion replacement) (#73)
• change examples to use the primary foaf:primaryTopic
