work on standardising on OpenRDF URI rather than OWLAPI IRI in APIs
where practical, to avoid casting/conversions

more migration to using URI instead of IRI, still broken build right now

broken progress difficulty is in OWLOntologyID and IRI.create with nulls

start standardising on IRI instead

remove accidental include

work on getting caching working correctly again

check caching for inferred ontology separate to the main ontology

extract an internal method to reuse it

fix test that was relying on an outdated schema management graph
structure

current schema management graph is synchronised with the manifest
format, and requires that the versions all have rdf:type owl:Ontology
and the base ontology have both owl:versionIRI and omv:currentVersion
