  - Assign AI-0508a to Donal Fellows

* Action Items Review

**  AI-0508a: 
    - The action to contact Taverna has no owner
    - One immediate question, following from the OGF20 discussion, is
      whether contacting projects for end-user use cases is the right
      approach
      - They might have actual use cases; it is worth asking
    - Taverna is based in Manchester and Donal is the person
      closest 
    - Donal agreed to contact them, but cannot do so until the week
      after next
      - This is not a problem since the next workflow call is in three
        weeks time
      - Eventually ask them to do a introductory presentation (see
        discussion further down)
    - Assigned action to Donal
    - Andreas will send reminder to Donal after 1 week

* Recap of discussion from the last F2F and followup

  - Consensus at the last F2F was for a community practice document,
    before making any decisions on technical work.
  - Who will contribute? 
    - No volunteers at this time. 
    - Some people indicated that they would be interested in the
      output; but not to work on producing it
  - Which language? Unclear
  - Does it include tools in addition to languages? 
    - Yes, if we are dealing with end user requirements.
  - Donal mentioned that his current project has a relevant survey
    report (a project deliverable) but unfortunately it cannot be
    released yet
  - It was suggested that the goal should be to do workflow with the
    services currently available/defined (BES, etc)

  - What tools are people using?

    - Windows Workflow  was mentioned. Also Platform, Kepler, ...

  AI-0614a: Steven Newhouse will check whether Windows Workflow can
           also be used with CCS / BES style services

  - Andrew volunteered to contact the Kepler project and arrange for a
    30 minutes presentation on a future call; with a focus on the use
    cases they are addressing.
    - Agreed to postpone this until the group can work out in more
      detail what the presentations should focus on
    - Andrew will send an email with the url of their website [done]

** Agreed on the following approach

    - Prepare a questionnaire and ask projects to fill it in
    - Select which projects to invite to give presentations based on
      the questionnaire replies
    - Provide an outline or key points that the presentations should
      address
    - Send invitations to projects once we decide what the
      presentations should focus on

** Suggested presentation points (initial draft)

    - How web services fit in
    - How security  is handled
    - What use cases are addressed
    - What standard tooling and standards are being using

    AI-0614b: Andreas will put the initial presentation points on the
             wiki

** Suggested questionnaire points (initial draft)

   - User base: grid or not
   - Technologies used: web services, or ..
   - Standard tools and standards are they basing their work on
   - If using a standard why did you choose it?
   - if chose to build your own; why?
   - User's key requirements; key decision making
   - number of deployments/ and how many users they have
   - What is their future release plan, i.e., where are they planning
     to be after one year (there were some reservations with adding
     this in)

    AI-0614c: Andreas will put the initial questionnaire points on the
             wiki

** Initial candidate list for presentations

    - Taverna
    - Kepler
    - Triana
    - OMII-bpel
    - Microsoft
    - Platform
    - Condor
    - Unicore
    - ...

 AI-0614d: Steve McGough will compile the list and put it on the wiki

  In addition to sending emails to specific projects it was agreed to
  send emails to the OGSA-WG list and to other related lists. One
  other list mentioned was the Workflow Management RG. Even though
  their current focus might be different. There are a number of
  communities represented there.

** Other input

   There was an ad-hoc BOF on workflow at the Berlin GGF. It might be
   worth reviewing the material from there, if available.

   AI-0614e: Steve McGough will look for the workflow material from
             the Berlin GGF


* Next workflow call -- July 5th
