Multiple inheritance not parsed to JSON

[danielapoliveira]

I converted the EFO ontology from OWL to JSON using obographs but I came across an issue when dealing with the representation of multiple inheritance in this ontology. For example, the class http://www.ebi.ac.uk/efo/EFO_0005117 has its parents represented as:

<owl:Class rdf:about="http://www.ebi.ac.uk/efo/EFO_0005117">
        <rdfs:subClassOf>
            <owl:Class>
                <owl:intersectionOf rdf:parseType="Collection">
                    <rdf:Description rdf:about="http://www.ebi.ac.uk/efo/EFO_0001444"/>
                    <owl:Restriction>
                        <owl:onProperty rdf:resource="http://purl.obolibrary.org/obo/IAO_0000136"/>
                        <owl:someValuesFrom rdf:resource="http://purl.obolibrary.org/obo/GO_0006954"/>
                    </owl:Restriction>
                    <owl:Restriction>
                        <owl:onProperty rdf:resource="http://purl.obolibrary.org/obo/IAO_0000136"/>
                        <owl:someValuesFrom rdf:resource="http://www.ebi.ac.uk/efo/EFO_0003786"/>
                    </owl:Restriction>
                </owl:intersectionOf>
            </owl:Class>
        </rdfs:subClassOf>
...

However, in the JSON file that obographs produces I can't find reference to these edges anywhere. Is the type of inheritance represented in some way that I'm not finding or is it not being parsed?

Thanks. Currently not all of OWL is supported.

Regardless of the export format I would recommend either relaxing to a logically equivalent form that is easier to use.

E.g.

C SubClassOf (G and R1 some Y1 and ... Rn some Yn)
<=>
C SubClassOf G
C SubClassOf R1 some Y1
...
C SubClassOf Rn some Yn

(I would also recommend separating the axioms this way in the edit version of the ontology but that's personal preference)

Thank you for the tip. I will look into finding a workaround then.
