[glue-wg] XML schema for GLUE 2.0

[JP Navarro]

Hi Balazs,

As others have described, there are several design, implementation, and
support advantages to a decomposed/flattened approach.  With unique IDs
and links between the entities, it should be fairly straightforward to
compose information into a large agreed/standard rendered document.

There are also discovery performance and functionality advantages and
disadvantages to both approaches.

It seems to me like this implementation approach doesn't contradict the
GLUE2 specification since it describes the same entities, attributes,
and relationships, although I think you're right that it may lead us to
modify the current rendering specification to include a decomposed  
one. An
interesting questions is whether we have to have a single XML rendering
in support of interoperability or if we can support several renderings?
We're already willing to accommodate XML, LDAP, and SQL renderings, so
why not accommodate multiple XML renderings too?

Regards,

JP
