I know that everything I say here will have a OWL, SPIN or whatever
equivalent that will do the job and there has been many examples in this
list before.
Personally I would prefer a language that (re)defines basic constraints
like domain, range & cardinality and does some basic calculations on
objects (e.g. patterns, string functions, language tags)
This means that the basic level of understanding would be RDF and allowed
values in subjects / predicates / objects, what is a class / property and
the meaning of rdfs domain & range.

Beyond that, I would prefer to provide SPARQL expression snippets e.g. (p1
> p2). So SPARQL querying would be an additional requirement for more
advanced rules
