unions in rdfs

[Bohms, H.M. (Michel)]

Is there some counterpart of “domain/ranges with owl unions” in RDFS?

(or are they lost?)

 

Thx Michel

As the RDFS spec says:

The RDF Schema class and property system is similar to the type systems of object-oriented programming languages such as Java. RDF Schema differs from many such systems in that instead of defining a class in terms of the properties its instances may have, RDF Schema describes properties in terms of the classes of resource to which they apply. This is the role of the domain and range mechanisms described in this specification. 

This specification does not attempt to enumerate all the possible forms of representing the meaning of RDF classes and properties. Instead, the RDF Schema strategy is to acknowledge that there are many techniques through which the meaning of classes and properties can be described. Richer vocabulary or 'ontology' languages such as OWL [OWL2-OVERVIEW], inference rule languages and other formalisms (for example temporal logics) will each contribute to our ability to capture meaningful generalizations about data in the Web.

See https://www.w3.org/TR/rdf-schema/

So, - No RDFS itself does support set theory operators for defining classes.

Cheers,

David

In RDFS, specifying two domains (or ranges) means an intersection.

There is no union option.

OK, thx Irene (and David)

 

So my single domains and ranges can stay but my xor domains/ranges go.

 

Ps

David, assume you meant in the end:

“So, - No RDFS itself does NOT support set theory operators for defining classes.”

 

(well, at least not union: intersection is the default)

Yep — NOT is indeed what I meant.
