Hi Anton, I'm (un)officially in charge of the topic. Right now I have identified the following topics/tasks, feel free to ask for more details on any one of them: 1) Use the ontology to create a fact model to write rules with : I'm perfecting the tool even now, in a few days the alpha version will be available for testing. It's meant to be pretty flexible, support many persistency techniques, provide convenience methods and will be integrated with the recent "traiting" (dynamic typing) technique. It makes some (reasonable) assumptions on the ontology, and would need use cases and consolidations. 1b) Once the fact model is there, we'd have to instantiate the individuals in the ontology as facts 1c) We have a side project to make this compatible with guvnor, to edit "semantically constrained" rules. 2) Use the definitions in the ontology to create classification rules. Would be "rule-style", in close world assumptions. My feeling is that it would create an execution framework for a SPIN-like language (or, if you prefer, a DRL version of the SPIN framework). I haven't started it yet, but could be done in a relatively few days 3) Use the definitions in the ontology to create a rule-based, object-oriented semantic reasoner. A proof of concept for a fuzzy semantic reasoner exists, but that definitely is on the TODO list. Help, as always, is appreciated :) This would be a necessary complement to the fact model, to ensure it's kept consistent with the ontology. Hi Davide Thanks, the work youre doing sounds really exciting and promising! I would very much like to follow your progress, and, if I can, help out. What is the best way to follow the progress of this project? Kind regards, Anton _______________________________________________ rules-users mailing list rules-users(a)lists.jboss.org https://lists.jboss.org/mailman/listinfo/rules-users
