RE: Implications and Issues in Converting UML to RDF/OWL When Constructing HL7 RIM Ontology

Hi Dan,   I think this is a good start. As others have suggested, we need to drill down further to understand our requirements and evaluate the need for representing RIM in OWL.. Some suggestions of deepening the use case are as follows: "An RDF system has been put in place to navigat

Hi Vipul, Excellent comments...It seems to me that an ontology that doesn't have a testable use case can never be judged useful or not useful for any kind of predictable search strategy. Here is the use case I would like to explore: "An RDF system has been put in place to navigate to healthcare res

I agree with Helen. In general, we need to be very careful about translating from the UML to the OWL meta-model. It is quite likely that there are multiple alternatives in OWL for representing the same UML construct and we would probably need best practices for the same.   Towards this

Thanks Helen, I have some questions on your notes below that I'm afraid will display my ignorance and naivete in RDF. In addition, I don't have access to Protege and some of my questions may be well-answered there. As you discussed classCodes and inheritance below, I didn't catch how moodCode was i
