> 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?

> 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

> 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.
