[ogsa-wg] Scoping for Job Creation and Management

[Ian Foster]

David:

As you know JSDL pretty well (certainly better than I, sorry to say), can 
you comment on whether the GT4 GRAM JDL (described at 
http://www-unix.globus.org/toolkit/docs/development/3.9.4/execution/wsgram/schemas/mjs_job_description.html) 
can be rendered in JSDL?

If the answer is yes, then I'd say first of all "good" and second "well 
that means we have work to do in terms of defining a standard vocabulary."

One more thought regarding your earlier email concerning scoping: you 
proposed that we take delegation off the table. However, one reason for 
delegating credentials is so that the job manager host can initiate staging 
commands.

Ian.
