Re: Schema.org and protege

Please also keep in mind that the domain and range in Schema.org<http://Schema.org> have different interpretation than their counterparts in OWL. So if a property in Schema.org<http://Schema.org> have two or more domains we take their union; OWL will intersect them. The same applies to the range.

Robert

The "schemaorg.owl" file that Richard pointed out can be loaded into Protégé.

But note that all schema.org<http://schema.org> properties will be seen as object properties in Protégé. Schema.org<http://Schema.org> (RDF in general) doesn't distinguish between datatype properties and object properties. Schema.org<http://Schema.org> datatypes (e.g. Boolean, Number, Text, etc.) are just RDFs classes and, because all schema.org<http://schema.org> properties have Text and URL in their range implicitly by default, they all become object properties during the OWL conversion process.

Hi Thejas,

If you use https://schema.org/docs/schemaorg.owl  you will find the domain & range values that are understood by Protégé.

Checkout  https://schema.org/docs/developers.html#experiments for details.

Hi,
The range and domain properties of schema.org<http://schema.org> are not supported by protégé. You need to replace does with rdfs:domain and rdfs:range in the schema file you are trying to import. Although this would be probably enough for protégé to load the schema.org<http://schema.org> properly, you would still need to work on the property definitions to make distinction between datatype and object properties.

Alternatively, you can try the experimental owl mapping, https://schema.org/docs/datamodel.html.

I am not sure if this one is up to date.

Greetings
Umut

Hi,

I had a quick question on how to import the ontology from schema.org<http://schema.org> into protege. I am able to import the ontology, however, the object properties are not imported. I was hoping someone from this list could provide into how to import the ontology.

Thank you,
Thejas
