Hi Adrian, 

Thanks for the slides. This discussion may be off topic for this WG. However,
since these slides were presented at an OGSA WG meeting -- just some comments. 
There are a number of workflow engines out there in the scientific domain -- 
very few of these actually support the BPEL standard. Not sure why this is. 

I certainly agree with your comments that something that could be used to define 
abstract workflows would be useful -- that could map into these existing workflow 
description schemes. Would certainly be useful to evaluate whether XPDL can map into
the representation schemes used by existing workflow engines -- such as Triana, Taverna, 
Kepler, Pegasus etc.  Certainly an interesting discussion to pursue. 
  

regards
Omer

Hi Adrian,

Could I have a copy of this by any chance?
      

Yes, I gave them to Hiro and Andreas, and they uploaded to the OGSA-WG 
site, that is avaible at this link:

Best regards,
Adrian

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.
 
          

I agree with you.
I held a presentation on the OGF'20 in Manchester, that is introduced 
the worklow interoperability levels and technics that had already 
defined in the WfMC documents...

    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
