All,

I have done the updates to the document discussed in the last two phone calls, and in the EMS meeting in Japan.

At a high level this includes modifications to adopt text/issues from the ESI document and the HPC profile working document. Note that this is NOT a final document.

These changes revolve around:

1: Changing CreateActivityFromJSDL to

a) take additional optional arguments, specifically notification arguments and an “idempotent” argument lifted from ESI.

b) An extension to JSDL suggested in ESI to support libraries

2: Adding a resource information model section. Originally to be from 4.1 of the ESI document – but post discussion with Snelling, Stokes, et al a modified 4.1.

3: State model. This is one of the biggest jobs. At GGF in Japan the HPC profile group introduced a nice, simple, extensible state model that would allow supporting a variety of state machines while still allowing basic clients to understand what they were getting. After discussions with many people I have decided to adopt that simpler state model. CLEARLY THIS WILL NEED DISCUSSION BY INTERESTED PARTIES. I AM NOT TRYING TO PULL A FAST ONE.  I have taken the text verbatim from the HPC profile paper. Note that I do not yet have permission from their lawyers – so we may need to yank this and retype the same info. I hope not.

4: Refer to managedjob “type” of EPR, just as we refer to “WS-Name” “type” of EPR.

I have not even tried to modify the WSDL and renderings. Once we decide on the rest of the content we can do that. So don’t read past page 20!

I am not sure of the status of the weekly call this week.  I will synch with Darren and Steven and send mail tomorrow.

I’m also including some slides from the discussion of BES in the EMS session.
