There has been a lot of discussion in the community concerning the
relationship between Web Services and the Grid. The Web Services Grid
Application Framework (WS-GAF) is a proposal on how Grid applications could
be built using existing Web Services specifications.
This work is the result of the collaboration between
the North-East Regional e-Science Centre
(NEReSC) and Arjuna Technologies.
There is a mailing list available for
discussions related to WS-GAF.
The initial message to the mailing list can
be found here.
The "work-in-progress" site contains
links to tools and services that are currently under development.
