Rainer Schmidt: --------------- I had a look at the short version of the SAGA spec. and send you some comments: I think the first tier covers all (and even more) of the general aspects of our use cases. Especially the file and job interfaces could be (partially) mapped well against our middleware. We require basic remote file handling, job submission, monitoring, and state inquiry. I'm not yet sure if I got Session and Context right but I think it would be feasible to integrate with our API and very helpful. I also like the idea of having an asynchronous API and the task interface. Of course, we would need to extend the API for accessing our VGE middleware specific services for e.g. service discovery, QoS negotiation or resource reservation. Hope this helps a litte!
