RE: [wsdm] AI: Definitions of some hard terms

wsdm message

1. You said [· An Endpoint Reference (EPR) is a reference that allows the client to communicate with a WS‑Resource.]

That is not very true, since an EPR is a reference that allows a client to comminicate with a Web service endpoint.

EPRs could also be used to reference a WS-Resource, in that case there is a WS-Resource Reference which is an EPR.

2. Should the Identity be described by all its mathematical characteristics. (information used to disambiguate... conforms to the following formulae...). Otherwise having the definition is worse than not having one.

3. sameness by identity is NOT equal to the sameness by reference. This has nothing to do with the EPR referring to something.

4. I suggest that "value having a role of identity" is not used, and "identifier" is used insted.

5. I think [· A manageable resource reference is used to allow a client to communicate with an entity: it expresses a communication endpoint to an entity.] is misleading and I suggest the following instead. [A manageable resource reference allows a client to access the manageable resource.]

6. What is the difference between the name and just another identifier of the resource, in your terms? Is it just the term of validity of the information?

Subject: [wsdm] AI: Definitions of some hard terms

Hi,
I've been promising this for a while, I think that we struggle with terms sometimes... and I think that having clear understanding of some common terms: Identity, Name, Label, Reference would help us in some of our conversations.

I'd like to propose the following as definitiions to be used in WSDM:
(See attached file: IdentityNameAddressDefinitions.doc)

Load up the arrows.
