Dear Neil, Geoff, Steve, Andre, Chris, I would like to invite you guys to re-ignite the discussion and standardisation efforts around parameter sweep definitions with JSDL. There hasn't been much activity since months, and from comments I received I think there is enough interest and effort now to get this done. As a starting point, please find attached the latest draft from June last year (*ahem*...). I am sure there are loads of things that need clarification and additional word-smithing, probably even some more features (or change of existing ones) - no pun intended ;). Please let's continue the discussion on the JSDL Mailing List (cc- ed); you may have to subscribe to the Mailing List before you can post to it. To do so, please visit http://www.ogf.org/mailman/ listinfo/jsdl-wg . You may also want to join the JSDL WG at OGF's Gridforge site: http://forge.ogf.org/sf/projects/jsdl-wg . Cheers, Michel
