How general is Owlready2?

Hi there

I have two general questions regarding the generality/applicability of Owlready2:
 
1- how limiting are the limitations to supported SPARQL constructs in Owlready2?
2- is Owlready2 meant specifically for biomedical ontologies and ultimately not really usable on any ontology?

I describe below the background to these questions.

Any feedback would be appreciated.

Thank you in advance.

Kind Regards,
Jos Lehmann



- Background -

I have been trying to get started with Owlready2 (v0.33), specifically from a dataiku python recipe.

Following the instructions on [1] and [2] I have managed to load & run very limited SPARQL-queries on the pizza ontology [3] as well as on an a private ontology loaded on dataiku.

I have not managed, though, to run what to me look like very simple queries, e.g. select all individuals of a given class in the ontology, I often get a "Lexing Error".

Before delving any deeper into Owlready2, I would to make sure that the Owl/Python interface is not limited wrt Owl 2 or SPARQL or other important Semantic Web standards
