If you'd like to see the XML Schema that I came up with for the recommendation, it is at http://software.teragrid.org/pacman/ctss4/glue2/glue2-1.0.0-r1/teragrid_glue_2.0_r01.xsd

Its structure is a little different from the XML Schemas from the working group. The main differences are:

* It is a flat structure with associations represented as references to the IDs of the associated entities.

* Many of the classes are included as top-level elements.

The main reason that I choose this approach was to make it easier to compose information from multiple sources. For example, I have one sensor that gathers information about jobs/activities and another that gathers information about nodes/execution environments. Plus other sensors on this system and other systems. I wanted to be able to run the sensors independently and then compose their results because the information the sensors gather changes at different time scales and the sensors can be on different systems. I felt that the composition would be easier if I avoided representing associations as sub-elements.

I also wanted the information provided by a sensor to be a valid document, so I have many classes as top-level elements. The XML Schemas from the working group only had Domains as a top-level element.

I'm not sure if folks will like or dislike these differences, but I thought I'd share them.

Hi Weijian,

I'm responsible for the XSD mapping together with Balazs. I had no time
in the last period to work on it.
The planned release date was 10 April
(http://forge.ogf.org/sf/wiki/do/viewPage/projects.glue-wg/wiki/ListOfImplementors)

In May, we will be able to release it.

Cheers, Sergio

I found a GLUE2 XML schema at
http://schemas.ogf.org/glue/2008/05/spec_2.0_d42_r01, but it is not
very consistent with GLUE spec v. 2.0.  Is there an updated one
consistent with GLUE 2 conceptual model? Thanks!

Cheers,

Weijian
