myGrid State of the Nation




  • extensions need to be rich enough to support replay/rerun/partial rerun.
  • should be able to take in grey-box provenance from external tools.
  • needs to capture user actions and decisions.


  • Using wfdesc to describe the workflows within components.
    • Using RightField (Note Kristina's observations).
  • Validation
    • Interface
    • Runtime (Input/output formats, etc)
  • Components are:
    • Independent
    • Encapsulated
    • Self-contained
    • Coherent
    • SP compliant


  • Should bleed between all tools.
    • So an annotation on a workflow in myExp should be attached to the workflow, not stuck in myExp.
