python: parse owl file in manchester syntax to owlready

Is it possible to parse an ontology given in manchester syntax such that it ends up as an owlready ontology-object.

This is what I found out so far:

• Owlready itself can only import "NTriples, RDF/XML or OWL/XML format" (ref1).

• Ontospy can (among other things) convert between these formats: ['xml', 'turtle', 'n3', 'nt', 'trix', 'rdfa'] (ref2).

• rdflib has a function rdflib.extras.infixowl.manchesterSyntax(...) but which seems not to be documented very well and seems not to be applicable to a whole file (or str with several statements).

Is there any othter project I am missing, or is there an easy way to combine (someOf) these projects to parse an owl file in manchester syntax to an owlready ontology?
