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

    • Quick:

    • 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?
