NTriples parsing error (or unrecognized file format) for DiseaseOntology

[adriata]

Hi,

I have problem with loading ontology from 'https://raw.githubusercontent.com/DiseaseOntology/HumanDiseaseOntology/master/src/ontology/doid.owl', I get error:
OwlReadyOntologyParsingError: NTriples parsing error (or unrecognized file format) in https://raw.githubusercontent.com/DiseaseOntology/HumanDiseaseOntology/master/src/ontology/ext.owl.

If I use Jupyter notebook with owlready2==0.21 I get error after first run and after second run it works fine.
I have this problem only with this onology.
Do you have any suggestions what can be done to get more robust solution?

Hi,

The problem is that the DOID ontology imports another ontology (IRI = //raw.githubusercontent.com/DiseaseOntology/HumanDiseaseOntology/master/src/ontology/ext.owl ). This imported ontology is in the OWL functional format, which is not supported by Owlready.

A solution is to download this ontology, to convert it to RDF/XML or NTriple, and to save it on disk in a local cache. Then, you can either load it before DOID, or add the local cache directory to onto_path.
