[rules-dev] Building a (semantic) application

Question, Are there any examples / tutorials to build, for example, some application using a Semantic backend. Are there specific frameworks or patterns. Maybe I'm ignorant on how to achieve this because of my background with MVC applications with an ORM and traditional 'out of the box' frameworks. Think it should be relevant the fact of using a semantic backend instead a relational one in the way one develop the application. For example, I think, there should be some kind of "Semantic MVC". I see lots and lots of features for semantic backends and interoperability. And some usage scenarios, but few implementation "roadmaps" to take advantage of all that features. Maybe I should think about one scenario where, my application semantics, my business domain for that application semantics, and that application data are making worth use of all those semantics. I'm posting my question on a couple of list, including one about rules, just because I think patterns developed out of rules community could help me clarify my view, and maybe have similar goals in respect to those of RDF. Shall someone share with me this existential questions, please let me know This file is all I could get more or less clear regarding this subject by now: http://cognescent.googlecode.com/files/architecturalDraft.pdf Regards, Sebastián. http://www.cognescent.com
