Hi, I also found* some interesting resource[1,2] re. property reification. > The following N3 rule would allow you to infer the shortcut property > from the longer form: > > { > ?cc > cco:agent ?s ; > cco:characteristic ?p ; > cco:topic ?o . > } > => { ?s ?p ?o . } . > So the abstraction of this rule looks then like this (see [3]): { ?p a :ReifiedProperty ; :reificationClass ?rc ; :subjectProperty ?sp ; :objectProperty ?op . ?r a ?rc ; ?sp ?s ; ?op ?o . } => { ?s ?p ?o } . However, then we need to make N3 rules** as a common available Semantic Web technology, or we have to introduce the terms of the Property Reification Vocabulary somehow as annotations terms for ontologies. Cheers, Bob *I'm every time surprised, when I found a quite good resource, which treat my issues, after a while (!). Sometimes (often) it is like to look for a needle in a haystack (which has a quite bad performance :\). I think that can't be the truth, or? (especially, if one "only" like to apply some technology, rather reinventing the things) **can I deliver N3 rules as part of my ontology definition?
