HI Laurence and Andrew,
I really would suggest that we make what is effectively Basic Information
Service. We have experience of trying to publish using glue based XML as
metadata on the MS HPC-BP service and it ended up creating some performance
issues. After building a separate service we also realised that as Laurence
suggested this same service can be used for different types of resources.
