I held this presentation in the WFM-RG section also. I hope, that I gave
ideas to Ian and Ewa to create the Grid workflows interoperability
standards.
Now I'm not focusing on workflows, beacuse my point of view is, that the
workflows are the top of the "Grid pyramid", and the standards of the
"bases" (basic services, date and job handling) are not fully finished
at this moment. So I'm focusing on brokering methods (how can we
implement the OGSA-CSS standards, not only for jobs), information
modelling and quota handling.
Best regards,
Adrian
