knora-admin ontology: project description cardinality

[lrosenth]

@subotic @benjamingeer
The old salsah now supports multiple project descriptions (for different languages). Therefore the
cardinality in knora-admin.ttl for the project descriptions should be changed to either

                          [ rdf:type owl:Restriction ;
                            owl:onProperty :projectDescription ;
                            owl:minCardinality "0"^^xsd:nonNegativeInteger
                          ] ,

or

                          [ rdf:type owl:Restriction ;
                            owl:onProperty :projectDescription ;
                            owl:minCardinality "1"^^xsd:nonNegativeInteger
                          ] ,

I would prefer the latter variant where we force to have at least one project description.
Who will change this – are there any objections?

Seems fine to me. In that case I guess it should also have a language tag.

It already does :-) It is a Seq[StringLiteralV2]. We would only need to change knora-admin.ttl and check that the payload for creating a project must at least contain one project description.

I just tried it out locally. Seems to be fine by just changing the cardinality in knora-admin.ttl... Thanks a lot!!
