And we have almost perfectly replicated the long thread on the Semantic Web/Ontologies topics from last year. It must be important. So far, the most illuminating point is that RDDL is a simple way to enable the site owner to assert their own "meaning" for a signal in a relationship in which they dominate the first transaction/sentence. If meaning is first discoverable then negotiable, RDDL is good for that first transaction. It is the negotiation that follows which was of interest in the original posting I made. That is, negotiating out noise means identifying what is and isn't signal in a succesion of exhanges, a conversation you will, the point of which is to ultimately exchange value. This is too abstract, I guess. If I want services, I am not yet to the point of negotiation of the file types; I need to know if the site supports those services. I don't know if RDDL is too much or just enough for that. What if one isn't at the point of exchanging XML or any document? Isn't a web service discovery system contingent on first identifying the types of resources one might want to choose from? What one might want is the offering (RFI) before the specification (RFP) and definitely before the contract (BAFO). It seems to me that focusing on RDDL hijacked other possibilities such as UDDI when essentially, RDDL is not deployed in many sites and UDDI is picking up momentum. "Only people have meaning" so the saying goes. I'll grant that. Only people really need computers too. A tool is a tool. What must be discoverable is "does he mean what I mean and if not, how shall we talk if I need him to mean what I mean?" len -----Original Message----- From: Simon St.Laurent [mailto:simonstl@s...] God aside, I think it's the nature of the subjects being discussed this particular week. URIs and semantics are both contentious zones, where using words in particular ways can madden people quickly. If you want real fun, try re-reading the xml-uri@w... archives, uri@w..., or urn-ietf@n... archives. My answer to the whole mess is simple: there ain't any meaning, just labels and structures. Anything else is a bonus or a nightmare, depending.
