Workflow Engine-based Approach
11Multi-Workflow Systems and Editors
• SHIWA based on gUSEsupporting ,e.g., Triana, Taverna, Kepler,
MOTEUR• Tavaxy based on Galaxy
supporting Galaxy and Taverna•MoSGrid based on gUSE
supporting Galaxy to gUSE, UNICORE in gUSE
Excellent solutions but can be extended…What happens if a
workflow changes?
⇒ Coarse-grained: users need access to the originworkflow
editor
⇒ Fine-grained: users needs to change the workflow in the origin
and in the targeted workflow editor

Workflow Editor-based Approach
16Multi-Workflow Systems and Editors
GeWWE (Generic Web-based Workflow Editor)Goal• One editor for
diverse workflow languages• Visual representation of workflows is
the same as in
the origin workflow editor• Easy integration of new workflow
languages
⇒ Same look-and-feel for editing diverse workflows⇒ One platform
for the whole life cycle of editing
workflows
