Hi all, FWIW, I have mixed feelings on this issue. 4 years ago I thought it would be just great to have exactly the same interface and end-point for job submission/management, for information query, and for file management. We even do have the same interface for job and file management: job is largely characterized by a set of files, after all. And information persistency may well be realized as a set of files, too - why not. But then I killed a job by accident, being sure I deleted a file. So now I think a clear separation is a good think to do.

Therefore if any such interface is defined in a future version of BES it should be encapsulated in its own optional port type. Steven

Laurence, First, as you can tell I am not a GLUE2 expert - nor am I keeping up with JSDL 2.0. :-) That said, as to your comment > One of the problems with getting the information from BES is that this > is then a service specific mechanism and other services such as the SRM, > etc. will have a different method. Information system interoperation is > indeed problem which we must solve but we need to deal with things in > manageable chunks. I agree completely. During the BES discussion we came to an impasse over this: some arguing that that we could use WS-RF resource properties ... and then have a single mechanism for all types of resources. Others, including but not limited to Microsoft, would have nothing to do with WS-RF. In the end to get consensus the WG decided on a separate function - very ugly. We in Genesis II support both the WS-RF mechanism and the OGSA-BES mechanism. The same thing by the way happened over notification, except in the end the WG basically punted. I personally think that the BES endpoint should provide a mechanism to get the information, but that the spec should be mute on how that information is aggregated or used.

Moreno, Once we figure out what we need I can start the process to get a new draft of BES out. Besides the state model - where we seem to have reached a consensus, and the "vector" operations, there is also the issue of moving towards GLUE2 as the attribute schema which has been discussed several times. We will need to be specific as to what part of GLUE2, and how to get the info from endpoints (we could keep the current mechanism). Finally, there is JSDL. It would be good if we could synchronize the transition to GLUE2 with the JSDL group. I am cc'ing the JSDL group as they may be able to better answer the question of JSDL and GLUE2 congruence (if there are any such plans.)
