Hello Balazs et al, I apologize for the long silence on this list. We'll try to finalize the XML Schema rendering by the end of the year. As far as I remember the arguments pro/con the two versions of the schema were: 1. Sergio/Balazs: hierarchical version pro: better readability, easier to query based on branch selection, exploits hierarchical nature of XML in natural way con: aggregating info from different info providers needs more care 2. TeraGrid/Warren: flat version pro: easier to aggregate bits of XML from different info provider con: less readable, does not exploit hierarch nature of XML in theory there is no reason for not having both; the important is that all the classes/attributes and relationships are represented; nevertheless, having one version improves chances for data exchange without further processing. At this point in time, probably it is better to go ahead with both and collect the experience. Based on this, adopters will make their on choice.

Dear All,
The completion of the glue2 specification in terms of updating (re- defining?) the renderings is still a pending issue. We have released the model but not yet the renderings.
I am happy to see that few groups started to work in this direction.
Let me point you to our wiki page where the different attempts are collected:
http://forge.gridforum.org/sf/wiki/do/viewPage/projects.glue-wg/wiki/GLUE2XM...
(linked from main glue wiki under Realizations to Concrete Data models)
Within nordugrid we have also worked a bit on the xml schema, more or less updated it to match the final specification. You can find the nordugrid version of the glue 2 xml schema here:
http://svn.nordugrid.org/trac/nordugrid/browser/arc1/trunk/doc/tech_doc/info...
and here is an example xml document based on that schema describing nordugrid resources:

Before the summer i started a discussion with Sergio about the xml rendering update, we wanted to start/speed up the rendering work a bit. Unfortunately, lots of other thing slowed down the idea.
All in all, I agree with Stephen that it has to be a community effort. I guess it is time to schedule for phone calls related to the xml rendering.
bye, Balazs Konya
