Re: [WFM-RG] [ogsa-wg] Workflow Interoperability and Sharing Survey for WFM-RG

The questionnaire is not suggesting that the issues are new. But they have not been solved in eScience, which is why they are worth addressing again. As you will see from the background paragraph in the email, and on the web form, we are interested in solutions and approaches that may actually be adopted by existing workflow tools. We are also interested in feedback from the community as these people work with existing tools, and may not have input into such organizations as the WfMC. Adrian Toth gave a presentation at the WFM-RG session at OGF20 which usefully described the WfMC approach. This represents just one approach which gravitates towards particular technologies that are not particularly supported by existing tools in eScience. We therefore consider it is worth eliciting opinions that may open up other avenues of thought. We are also interested in generating discussion in this area, so it's obviously working. cheers, Andrew On 21 Feb 2008, at 11:14, Jinjun Chen wrote:

Workflow interoperability and sharing are not a new topic. They have already been there since 1993 when WfMC was established. I would like to suggest that we pay more attention to what have been done by WfMC.

Best wishes, Jinjun

I've been asked to circulate this on behalf of the WFM-RG. Please consider replying as this will hopefully feed into future OGSA as well as WFM-RG work.

Dear Researcher,

As part of the work of the OGF Workflow Management Research Group, we are gathering user scenarios and experiences on workflow interoperability and sharing, which we intend will lead into a research document. Andrew Harrison (group secretary) has created an on-line form to gather information for such a research group document, which can be found here:

We would appreciate your help in taking the time to answer these questions and provide us with your opinions on these topics. As a background:

There are a number of existing workflow tools and systems used by different projects in the eScience community. Many of these projects have a long history of activity and have, as a result, developed specialist knowledge in certain domains as well as particular capabilities that support the scenarios the project has been addressing. The relative maturity of these projects means that imposing standards which would disrupt their development or diminish the availability of their specialisms could be counter-productive. At OGF20 and OGF21, the Workflow Management Research Group (WFM-RG) focussed on gathering and disseminating workflow sharing and interoperability scenarios and requirements in an attempt to begin developing standards and mechanisms that allow diverse workflow systems to interoperate without undermining their individual strengths or development procedures. This document is a request for input into that process. It will not take long to complete. We would like to thank all those in advance who contribute.

All the best,

Ian and Ewa
