Hi,

We intend to convert an RDFS/OWL ontology to a shape file and, from then on, work with SHACL.

So, we are very happy with the conversion functionality.

It appears that unions of datatype ranges are not converted. Thus,

x:someProperty

rdf:type owl:DatatypeProperty ;

rdfs:domain x:Domain ;

rdfs:range [

rdf:type owl:Class ;

owl:unionOf (

xsd:date

xsd:gYearMonth

xsd:gYear

) ;

] ;

.

Results in:

x:Domain-someProperty

rdf:type sh:PropertyShape ;

sh:path x:someProperty ;

.

With no range indicated. Unions that are the value of rdfs:domain are converted correctly. Best regards, -Jan

FYI it’s not hard to extend the OWL2SHACL capability to handle more complex cases.

See https://www.topquadrant.com/doc/7.2/user_guide/guidance_specific_to_asset_collection_type/working_with_ontologies/shacl_enablement.html

Cheers,

David

I have added two cases (owl:unionOf with length 2 and 3 in the attached update, which will also be part of TopBraid 7.3. Handling arbitrary length lists would require JavaScript but I hope the provided solution will keep you going.

Jan, I would appreciate if you could test this and let us know if it works.

Hi

can anyone in TQ shed any light on the copyright status of the owl2shacl rules - there is no metadata in the file and this is posted on a public access forum, so is there any impediment to utilising it in an open source project?

cheers

Hi Rob,

yes you can freely use that one, with no strings attached. We are always happy if ontologies get converted from OWL to SHACL :)

Do you have a specific metadata annotation in mind so that we can clarify this, i.e. what license would you suggest for such things?

Note this rule does NOT apply to all ontologies bundled with TopBraid.
