4) OGSA workflow discussion (Andrew, 30 min)
Minutes from Nov. 30th call
> - Mark runs the group through the slides "Workflow thoughts"
> provided by Andrew, Steve and Mark
> - OGSA could either pick a specific Workflow language, and
> alienate everybody else
> - Alternatively, OGSA could pick none and create a new one,
> and also alienate everybody else
> - Orchestration and workflow must be separated
> - OGF is best served with simplicity
> - The proposal is as follows
> -- stay away from language and API specification
> -- Tightly scope WFDL (Workflow Definition Language)
> -- Ensure reasonable mappings from existing systems into WFDL
> -- Toos support
> -- Reuse as much existing as possible
> - WFDL is XML based and describes directed graphs
> - Nodes are WFDL, ord JSDL
> - Nodes have labelled input and output
> - Mark walks the group along a sample WFDL instance document
> - Jay: This example is a dataflow graph, not a workflow graph
> -- Mark: Example 2 demonstrates other kinds of dependencies than
> data dependencies
> - Jay: Dependencies should be expressed as resources produced and
> resources consumed
> - The group discusses Jays suggestion
> - Jay points out that the Workflow effort should be very carefully
> evaluated against the current other efforts related to JSDL
> - Chris: Defining (yet another) WF language is probably a bad idea
> -- This would, among others, add delay
> -- Andrew: As pointed out on the slides earlier, picking a
> particular WF language or creating one is a matter of "choose your poison".
> -- Fabio: We probably should focus first on listing the requirements the
> languuage should meet
> -- Jay: I believe it is possible to combine this workflow effort with current
> efforts for JSDL and Information modelling
> - The group discusses possible further steps from here on
> - Andrew: After this first initial investigation, does OGSA think that the WF
> issue is important enough to set forth a design team now, or postpone for
> the moment
> - Andrew proposes to set up a separate phone connference with a specific WF agenda
> -- Jav and Michel support the idea
> - The group discusses the appointment for the next WF call
> - Jay proposes to use OGSA's Gridforge wiki to collect people's requirements,
> dependencies, favourite existing WF solutions, etc. together to get an overview
> on what's necessary and what's not.
> -- The group reaches rough consensus to picck up this idea
