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
