  |   | 
  |   | (i) the "physical" name, which is the EPR and needed to address the service. This name may be obtained from the Registry or from elsewhere. But the Registry is the preferred approach.
  |   | 
  |   | (ii) the "logical" name, which is a convenient short-hand, like "Kurt's Travel Agency". Obviously in order to interact with a service you need a real address, so if all you've got is a logical name you need some way of mapping one to the other. That's where the Registry comes in again. The Registry maintains a tuple space of <logical name, physical name>.

  |   | We could set the logical name as the URI. As you say, something like: epr:jbossesb:version:1.0:logicalname:KurtsTravelAgency
  | 
  | Every Service and ServiceBinding can have a name. This name is used when querying for a service. The physical and logic names you refer to are more 'addresses' to me. But I agree with what you say.

  | OK so I guess we now have:
  | -ServiceBinding.name = "Kurt's Travel Angency"
  | -ServiceBinding.URI = "epr:jbossesb:version:1.0:logicalname:KurtsTravelAgency"
  | I'm going to see how we should be using the 'tModel' to store the EPR. I think it will be something like this:
  | -ServiceBinding.Concept = the EPR-XML
  | -ServiceBinding.Classification = "jbossesb-aware"
  | but let me look into this a little.
  | 
  | I pretty sure we gain searchability from classifying things. So the way we organize things may help us when searching for a Service.

This is all in a state of flux now that WS-A has become a standard and UDDI evolves. However, what we do for the initial release doesn't necessarily have to be the way we continue to do things. So I think if we can agree on a "good enough" approach for the 4.0 release, we can revisit this later.
