my experience
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

    • Long term:
  • Lessons
lessons
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?
