Abstract:
A client accepts 20 an input query, rewrites 22 the query and forwards 24 the query to a database server, which returns 26 results which are then rewritten 28. The database includes classes arranged hierarchically as superclasses and subclasses, and/or properties also arranged hierarchically as superproperties and subproperties. In embodiments, the query is rewritten 22 to replace each instance of each class and each property in the input query with the transitive closure of the respective class or property. The client allows inferencing whether or not this is supported by the database server.
