[gin-info] Site UniqueID

[Laurence Field]

We have shown that for the "grid-on-a-map" use case we MUST have the 
following attributes

UniqueID:
Latitude: 
Longitude:
Location:

SHOULD have the following attributes.

Name:
Description: 
Email:
Web:

and CAN have optional tagging attributes.

On question that remains is what should be the format of the UniqueID. 
This is important as when we have interoperating grids, the rules to 
chose this UniqueID in the different grid might not be the same and 
hence this could case a clash.  This is a similar problem to the VO 
naming issue which came up in the gin-auth group.  In the past a 
suggestion was made that this should be the domain name of the site.   
What are peoples views on this? Do they think that this is a good idea 
or can anyone suggest a better alternative?
