Updated project location and description.
European projects K-Wf Grid and CoreGRID I established a Grid Workflow Forum as an open forum for information exchange and discussions about scientific and commercial approaches in the domain of Grid Workflows.
GRMS is a persistent GSI-enabled Web Service in GridLab project under GPL in Java using CoG (uses Pre-WS GT). Provides both command line and GridSphere Web portlet interface. Has its own workflow language (DAG/PetriNet).
Fiswidgets looks like nice Java GUI and simple to use workflow tool that may be in future integrated with Grid. Additional background (only abstracts available): overview from 2002 publication and from 2003 and some additional external FisWidgets.
The fiswidgets project is developing Java graphical user interfaces for a number of neuroimaging analysis packages (e.g. AIR, AFNI), and a graphical computing environment (analysis desktop) in which to link together individual graphical user interfaces as subcomponents in multi-step processing streams. The software consists of the current set of graphical user interfaces, the desktop and workbench computing environments, and, the Java toolkit (API) used to create graphical user interfaces.
(...) Fiswidgets development is funded jointly by the National Institute of Mental Health, National Institute of Neurological Disorders and Stroke, and National Cancer Institute, under the auspices of the Neuroinformatics/Human Brain Project, grant #RO1 MH62006, Usability and Interoperability of Neuroimaging Software.
