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

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.

Dear All,
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,
