Hi, I am wondering whether the OWL language enables us to define a class restriction using the boolean value. In the ABox we can say that :instance1 :property1 "true"^^xsd:boolean :instance2 :property1 "true"^^xsd:boolean :instance3 :property1 "false"^^xsd:boolean Is it possible to define the OWL class having all instances with :property1 assigned to the true value? We can use facets with strings, numbers etc. in OWL but it seems to me that we cannot use facets with boolean values as the OWL 2 Web Ontology Language Structural Specification says "No constraining facet is normative for this [boolean] datatype." [1] Is there some way to express such restrictions using boolean values in OWL? Thank you Regards, Ondrej [1] https://www.w3.org/TR/owl2-syntax/#Boolean_Values -- Ondřej Zamazal Department of Information and Knowledge Engineering University of Economics, Prague https://nb.vse.cz/~svabo/
