Hello, I'm currently working on dynamic collection definition and try to express it in OWL format. I would like to specify a class for which all instances are defined in intention by a query. The only way I found is to put a property "query" which has a literal value and contained the query. As far as i know, this representation, by the mean of OWL restriction, is not possible (i may be wrong) . Example : The class of native places of 19th century romantic composers, as retrieved by the following SPARQL Query on dbpedia SELECT ?x WHERE { ?c dbpprop:birthPlace ?x. ?c a <http://dbpedia.org/class/yago/RomanticComposers>. ?c dbpprop:birth ?b. ?c dbpprop:death ?d. FILTER (?b > 1800) FILTER (?d <1900) } Is there a way to define in OWL, membership of a class with a query ? Thank you, Pierre-Yves.
