Stanley; What you are describing is the RDFS inference for rdfs:subClassOf. For example, Composer's Instances View shows all rdfs:subClassOf inferences by default. You can turn this inference off by un-selecting "Show indirect instances" in the context menu for the Instances View.
A common misconception is the rdfs:subClassOf inferencing is defined when the rdfs:subClassOf property is created. RDFS works differently than OO paradigms in that class membership is computed by inferencing, not pre-defined at compile time. This allows the definition of class membership to be modified depending on run-time characteristics. rdfs:Class/owl:Class are more accurately thought of as containers for set membership than instances in the OO sense. Ensemble is a Web-based thin client interface. All data processing occurs on the server back-end, TopBraid Live. Ensemble invokes back- end processing though SPARQLMotion scripts and this is where you can set up data processing such as OWL inferencing. Take a quick look at http://www.topquadrant.com/products/TBS_FAQ.html#TBE4 for a start. We will augment this with a detailed example of how to perform OWL inference by the end of the day. If you are using TBL Personal Server (TBC-ME running on localhost: 8083), then you can open you model and run inferences on it. Ensemble will read the file (via the file's base URI) from memory and display all asserted and inferred triples. -- Scott On May 16, 9:20 am, Stanley <[email protected]> wrote: > I have a question about Instance > > In Ontology, Classes may be organized into a superclass-subclass > hierarchy, which is also known as taxonomy.
