An appropriate inference from the presence of a resource in a facet list is that it is of type :Facet. The general approach to RDF is to treat it as an open world: if something is asserted to be black and also asserted to be white, a proper resolution is that it is both, not that one of the assertions is wrong. Likewise, because a resource is in the facet list, the proper resolution is that it is in fact a facet, not that it is misplaced or not typed correctly. > If yes, is it the right way to assign those properties :Facet as an > additional type? The above description is actually the way the Fresnel engine operates - you don't need to assert that something is a :Lens, just that it applies to a particular type or instance (or other valid lens selector). So the short answer is no, you don't need to do anything special regarding the :Facet type. -- Ryan Lee [EMAIL PROTECTED] MIT CSAIL Research Staff http://simile.mit.edu/ http://people.csail.mit.edu/ryanlee/ _______________________________________________ General mailing list [email protected] http://simile.mit.edu/mailman/listinfo/general
