11. Session 2 • Some observations from previous events • Discussion issues

12. Some observations

13. High lights • Interoperability between different scientific workflows • Semantic integration • Human in the loop interaction • Provenance • Cooperative working

14. My experience • Virtual Laboratory for e-Science • Horizontal: Six application domains • Vertical: Expertise at different levels: application, workflow developer, Grid etc. • Motivation: cooperation, knowledge sharing and transferring, and innovative e-Science • We realize: workflow is a core service to glue things • Approach • Quick: • Long term: • Lessons

15. Lessons • Usability of workflow systems, • Developers: Good architecture and engineering • Scientists: Evolving requirements in order to do creative work after using a system • Lesson: how to bridge the gap • Interoperability between systems • Developers: extending existing developments to meet new integration requirements, • Scientists: share/reuse components/workflows between domains and systems • Lesson: a better engineering approach • What did you lean?

16. Free discussion

17. Coming event • WSES 08 (Workflow systems in e-Science)in IEEE CCGrid, France. • Submission deadline 16/Dec/2007 • http://staff.science.uva.nl/~zhiming/workshop/wses/
