Hi Dan,
we are developing the Grid Programming Environment (GPE) as an Open Source project (http://gpe4gtk.sourceforge.net). Our goal is to provide graphical user interfaces and programming tools for Grid end users and developers, independent of the underlying Grid Middleware. Therefore we have defined a programming API and a set of so-called "atomic services" that manage jobs, files and (virtual) machines on a Grid system. Currently we have implementations of the atomic services for GT4 and for UNICORE6.
A major problem that we have to struggle with is the difference in the WSRF/WSN specification versions since UNICORE is using the final versions. So right now we have to provide two different API implementations and client distributions. Synchronizing the WSRF/ WSN specs between GT4 and UNICORE would allow us to use the same clients for both server-side implementations, which is actually what we assumed would happen some day.
The second issue is, that we would like to switch to a modern SOAP framework, like Axis2, XFire or Jax-WS. Last time I looked at the Axis2-based Muse, the implementation looked quite similar to GT4, although security is missing of course. So migrating from GT4-core to Muse seems to require the least modifications, but I may be wrong there....
And finally there's the WS-RT family of management standards coming up, that let's people assume the implementation will change again some day.
As a summary, we'd be happy if GT4 only upgrades the WSRF/WSN specs for now. But we need a concrete roadmap that allows us to plan our GPE development for GT. One option could be to implement GT5 on top of Muse and then in the long term move towards WS-RT together with the Muse project, or?

Hi Committers,
The CDIGS team is currently evaluating whether we need to update the Java WS Core and C WS Core at this time to conform to the final version of the WSRF specifications. Depending on the implementation model, this could increase both the support and implementation complexity of the toolkit. We would like to have some email discussion on this topic to understand what your requirements are and determine the best course to pursue.
Joe, Rachana, Charles, and Ravi have been diligently working to put together the attached document. Please help us understand if the benefits of upgrading are worth the increased support/ implementation complexity and lack of backward compatability for our user community.
I would also like to propose a concall meeting on Monday May 14 at 11:00am CT to discuss this further.
Thank you,
Dan
