Dear all, I am comparing different approaches for modelling "attributes":
1. Simple/most direct as OWL datatype properties 2. As classes to allow for more meta-data like units 3. As named individuals according to QUDT2.0 (NASA/TQ). One of the criteria is the complexity of restrictions. As example I look at a card=1 restriction for a height attribute for a Bridge class. The first 2 are quite easy (the first is most simple/direct OWL, the second option needs some property chaining) but the third one I am unsure whether I can stay within OWL or that I have to move into SPIN/SHACL/.... territory. EXAMPLE Having from qudt2.0: qudt:hasQuantity, qudt:hasValue, qudt:Quantity, qudt:hasQuantityKind. And defined: :Bridge rdf:type owl:Class . :Height rdf:type qudt:QuantityKind . I am looking for an OWL (RDFS/RDF)-based restriction for the red part below (avoiding extra explicit subclasses): :Bridge rdf:type owl:Class ; rdfs:subClassOf [rdf:type owl:restriction ; "there exists one Quantity via qudt:hasQuantity, having qudt:hasQuantityKind=:Height . owl:hasValue doesn't seem to help because it's too restrictive (there can be other attributes). owl:someValuesFrom seems to work on the class-level only some special expression possible? ie some QCR (card=1) on qudt:hasQuantity where the Qualified-part is an intersection of qudt:Quantity AND owl:hasValue qudt:hasQuantity=Height? Thx a lot for your advice! Or suggestion for a more general forum to post such a question...(apologies upfront) Michel Böhms, TNO (NL) Dr. ir. H.M.
