As I recall, the reason for UDDI and other discovery processes is to provide a facade of what is public knowledge so that one can then begin a negotiation to get more private knowledge, therefore, establish a relationship. Typical contracting works like that and I won't get into details here. Pragmatics takes up that aspect of communication. Ontologies are a way to get that done but there is no free semantic lunch. Standard ontologies are one answer, but you'll find the debate about the uppermost ontology to be fatiguing. When you look into business intelligence systems (eg, applications of OLAP cubes vs massive indexing over distributed resources), you will find the ontology challenge yet again. What I am still sorting out is if there is a clean separation of the pragmatic and the semantic layer. I sort of doubt it but I'm still learning. On the other hand, except for methods, it can be hard to tell the difference between a document and an object even if you can tell the difference between an object and data. That means document is overloaded and ambiguous, so it is a classic term that exists in superposition until measured. The point of pragmatics, I guess, is a formal means to establish a protocol of measures, aka, "right rock; wrong rock". len
