Hello all,

    I wanted to support Andrew's comments here. We are of course aware of the good work achieved on interoperability by WfMC.  However, such an approach is aimed primarily at B2B interactions and their standards for interoperability were released around 9 years ago.  If the subject was closed, then the eScience community would have adopted this approach and we would indeed have no need for further debate (and indeed, perhaps we should consider adopting these standards ...).  However, this is generally not the case in eScience workflow and it would be very useful to have the community feedback on their experiences with WfMC or other.  There are a number of interesting workflow projects around in the community and recently there has been activity in the area of workflow sharing (e.g. myExperiment and others) for the scientific workflow community rather than business community.  Whether the WfMC B2B is relevant here it a matter for discussion.

    The aim of the questionnaire is is to get people motivated in discussing these issues, which we hope might lead to a research document that will include a review of relevant standards. We hope that many will take part in this discussion and we also hope that some might even contribute to the document :) Your help is appreciated.

cheers,

Ian

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.

Best wishes,
Jinjun

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:


http://bender.astro.cf.ac.uk/wfmrg/


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
