Donal, On a similar note, what is the current status of JSDL? Roughly when can we expect the final release to be ready? Sorry, I've not been following closely the mailing list. Thanks. ----------------------------------------- Melvin Koh Chee Kian Grid Research Engineer Asia Pacific Science & Technology Center Sun Microsystems Inc.

I was browsing around for GGF13 when I chanced upon JSDL archived discussions on JSDL. You appear to be answering some of the questions so I thought I could write to you for my perhaps overly-simplistic question:
What is JSDL? Is it some kind of Job Service Description Language? The team appears to be designing a kind of resource description XSD schema.
JSDL stands for Job Submission Description Language, and it's purpose is to describe simple job descriptions. By simple, I mean a single invocation of some program (or a webservice or an SQL lookup or whateverelse you want to do with extensibility), with possibly some files staged in beforehand and staged out afterwards.
We are aware that it is an incomplete solution to the general problem of job and workflow running on the grid. This because we envisage other languages that mix into JSDL or wrap around JSDL to provide these extended sets of functionality; we're trying to keep the focus of JSDL itself small so that we can achieve a defined task in as short a time as possible. This is covered in the specification (see Figure 2) though it needs some more explanatory text.
Could you give some pointers on JSDL, latest alpha/beta/full versions of XSDs available, or any info to me please?
The documents at https://forge.gridforum.org/projects/jsdl-wg/docman/ are a out of date, but not very far out of date. There are aspects of the document though that may change before we do a final release. To understand these, you'll probably need to attend the teleconference. Contact details for that are sent out on the JSDL mailing list (which this message is cc'ed to) and can be looked up in the archive of the mailing list on the JSDL website. http://www-unix.gridforum.org/mail_archive/jsdl-wg/threads.html
