Hi;

I totally agree.  You make a very important point.

That said, the simplest common case to define may be an array of
available resources.  Specifying richer policy restrictions can quickly
lead down the slippery slope to very complicated, very
difficult-to-provide designs and hence must be done with great care.

Marvin.

One thing Donal mentioned which I would like to emphasize:

The discovery ought to be "what types of job are acceptable" and not
what resources are there.  Or rather, the latter is part of some
administrative interface which is misleading for job-submitting users
and middleware.

This may sound pedantic, but it will be crucial for interop. The
discovery has to capture realistic operating policy, and not just give
enticing catalogues of resources which can never be combined in a
single request!
