No, I agree for now EPR is what we should be going after, I just brought this up as an analogy.

  | 
  | (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>.

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.
