1 – Is this a syntactic or a semantic restriction?

Simple entailment RDF doesn't express e.g. cardinalities,  so I was imaging a profile to have syntactic restrictions c.f. SHACL.

The target domain does not have semantics. We have to consider whether higher-level semantics imply anything about the target domain.

LPGs do have a semantic interpretation (definition 2 and 3 in [1]), which is captured consistently by the RDF encoding with the either the syntactic or the semantic restrictions.
