I have some basic questions: 1. How an ontology as compared to logical data model? We do have a logical data model now why we need an ontology? 2. I need to import a PowerDesigner (pdm file) Data model into topbraid. Any tips on how to do this? Appreciate any response on these Thanks --- On Thu, 9/29/11, Bohms, H.M.

(Michel) <[email protected]> Subject: [topbraid-users] two rule-issues: CWA & instance rules To: "[email protected]" <[email protected]> Date: Thursday, September 29, 2011, 8:29 AM In figuring out the best way to model etc. rules I run into 2 specific issues. 1. CWA <> OWA I know and understand the typical example involving card=1. CWA: 1 allowed; OWA: if more, they are inferred the same. But how does it work in owl2 (no spin) with 'value examples'. Like age > 0 and age fact of individual = -3. What is the OWA interpretation now? (something like "anything"=true beacuse inconsistent or what?) 2. using some own meta-models up to know for rule modelling we could even model rules on instance level. ie there is an instance wall_1 for which we know height>10m or which should have height>10m. How would that work in spin: do we always have to introduce extra classes to deal with such constraints? typical example "in-the-middle": front tires of a car: min 2.3bar pressure, back tires min 2.5 bar. In our meta-models: we attach 2x2 constraints to four tire instances (having/needing one Tire class only). Using owl directly it seems we can only introduce the class FrontTire RearTire or even FronLeftTire etc. and then instaniate all classes one time.Would be interested in your view. Thanks for any views on these two modelling/rule issues. Michel Dr. ir. H.M.
