Artifact artf6087 : Consider use of terms "entity" & "identity"
Tracker: OGSA Architecture
Title: Consider use of terms "entity" & "identity"
Description:
In public comments for the OGSA Glossary v1.6, Allen Luniewski made the following comment regarding entity and identity.
  On the OGSA telecon of November 19, 2007 we decided that this should be submitted as a tracker to be considered as an 
update in the next revision of the Architecture document, and that the Glossary definitions should then be updated to 
reflect any changes made.

Allen's comments:

Entity/Identity.  An entity is defined as "Any nameable thing."  This implies that to be an entity in the OGSA 
environment the thing must have a name.  Since the definition of "name" is very general (especially the "address" 
component of it), it is hard to say that this is wrong.  but it certainly is a bit misleading.  When one looks at the 
definition of identity ("An attribute, such as a name, that allows one entity to be distinguished from all others.".  
This seems to reinforce the point by implying that an entity only needs to have an identity and that the identity might 
be something other than a name.

** Additional comment from Allen in e-mail to Jem 11/29/2007: My off the cuff solution would be to change the definition
 of entity to read "Any uniquely identifiable thing." The idea is that an entity is a thing that can be denoted in some 
manner that gets one precisely to that thing.

** Additional comment from Donal Fellows 12/6/200, also commenting on the Glossary 1.6: Entity - should mention that 
entities may have state.
