Hi Holger, Thx a lot! Non-meta response still very much appreciated :) but in future I will post generic questions to the other list, Michel

From: topbraid-users@googlegroups.com [mailto:topbraid-users@googlegroups.com] On Behalf Of Holger Knublauch Sent: dinsdag 27 mei 2014 0:56 To: topbraid-users@googlegroups.com Subject: Re: [topbraid-users] discriminating for context Hi Michel, just a meta-response: for general modeling advice that is unrelated to TopBraid, you may want to post your question to http://answers.semanticweb.com/ where you should also get a wider range of viewpoints. HTH Holger On 5/27/2014 0:34, Bohms, H.M. (Michel) wrote: Dear all, I'd like your advice on a specific modelling pattern. In our taxonomies we use as much as possible "discriminators" that are datatype properties that get a class-level value (hasValue) relevant for all individuals. Sometimes however, we want to discriminate according to something like "application area" that refers to a (another) class in the ontology. We cannot do a similar thing as with datatype property discriminators (like a discriminating object property) because we don't want to discriminate wrt values/refs of classes but more on the classes itself (its more a meta object property in fact). So for now we define an datatype property "applicationArea" and put the relevant class names as enumeration items. Clearly this feels a bit double and asking for inconsistencies (keeping relevant classes and related enumeration items in sync). We would welcome ideas on THE way to do this in OWL (would it involve for instance reification?). I want to conclude with a simple example. A. Class Engine (next to Class Car, Plane, Ship,...) B. DatatypeProperty aplicationArea, datatype [Car, Plane, Ship,....] C. Class CarEngine SubClassOf Engine aplicationArea hasValue Car but maybe better done something like: A. Class Engine, Car, Plane, Ship B. ObjectProperty applicationArea (with range: owl:Class) (we don't like this because we want to model properties as datatypeproperties...) C. Class CarEngine SubClasOf Engine applicationArea "hasValue" Car or better....??? Thx a lot, Michel and Lieke Dr. ir. H.M.
