[XML-DEV Mailing List Archive Home] [By Thread] [By Date] [Recent Entries] [Reply To This Message] Re: SW-Mapping to OOP Model
 Hmm, IANAL but there's seems a bit of a gap between the declarative+operational semantics of most OO languages and straight declarative semantics around the RDF stack. Having said that, they do have pretty much the same theoretical (and historical) foundations - sets, then frames and all that. I do think there are a lot of relatively unexplored regions (and tuplespaces [1]) around here (on my rainy-day list is to play with some of the RDF/OWL inheritance logic(/DL subsumption, see [2]) in Smalltalk, replacing the standard mechanisms in places). But as you suggest, there's probably a lot of fun potential around automatic interaction in the Web environment. fyi, OWL-S [3] is about services, again it's essentially descriptive, with WSDL grounding. Cheers, Danny.
