Dear colleagues, Whether you choose a flat structure or a hierarchy, the important fact is that you query the system using the Foreign Keys instead of the structure itself, so we ensure compatibility between the different data systems implemented.

We were in the same position as you are on TeraGrid, which is why we defined our own schema. If you'd like to use the TeraGrid schema, I'd be happy to answer any questions you have about it. Also feel free to take it and modify it as you like.
Of course, the TeraGrid GLUE 2 XML Schema isn't a standard and I can't say how similar it will be to an official OGF GLUE 2 XML Schema. In fact, one warning I'd give about the TeraGrid schema is that we chose a flat hierarchy of XML elements in that schema (e.g. ComputeActivity is a sibling of ComputeShare instead of a child of ComputeShare). The last discussions I remember seeing on the GLUE working group list seemed to have more people favoring a deeper hierarchy...

Hi,
Grimoires, the OMII-UK service discovery implementation, currently supports GLUE 1.3, but we wish to update this to support an XML schema rendering of GLUE2. Given that there isn't currently an up-to-date XML schema for GLUE2 from the WG, we were wondering how best to proceed. We're aware that there is an XML schema developed by TeraGrid - would this be an appropriate way forward until one is developed within the WG?
Any advice gratefully received!
Best Regards,
Steve Crouch
