Hi Dave,

The method could produce a list of data type properties. Thanks again for your 
suggestion.
Is it possible to know the corresponding classes of the properties?

If you mean domain/range declarations then yes a DatatypeProperty is an OntProperty which in turn supports listRange() and listDomain().

Beware that if your ontology has complex domain/range expressions (e.g. boolean combinations) then all that listRange/listDomain will give you back is access to those class expressions.

You may find the OntAPI manual helpful:
