When defining an Ontology using OWL, is there a way to say that a class

  • should always be an Anonymous Node
    (no rdf:about=”…”) e.g. <my:FamousQuote/>
  • is abstract and any Instance of this class should
    always use a subClass

(edited here:)

  • that a DataTypeProperty should match a regular expression ?

Thanks

    OWL (in general) is about entailments given a set of RDF, not about validation (especially with regards to structure).

    • There is no way in OWL 1.1 to know if a node is anonymous or not. OWL 2 does not seem to support this either (via a owl:Restriction, for example).
    • For the abstract class requirement, this post on the Protege mailing list has some ideas on how to do this.
    • OWL 1.1 DatatypeProperties do not support “validation” of a given statement’s object. OWL 2 has datatype facets (including xsd:pattern) which you could potentially use.

    Update: You may be able to use SPIN to query the graph structure and contents in order to infer new triples.
