I think a single 90 minute session as well. Do you want me to schedule it?

Fwd: RE: [ogsa-bes-wg] Proposed changes to Spec.
by Ian Foster 09 Dec '05

09 Dec '05

Hi, I wanted to follow up on my email below. There wasn't any response to the concern I raised concerning the proposed operations, and I think it is an important issue that should be discussed. I realize that the BES management might reply that I need to join the phone calls, but that isn't easy for me, and I think that we should be able to discuss issues on the email list also. Regards, Ian. >>Darren: >> >>I would like to argue against your proposed operations on the grounds of >>fragility and scalability. Your operation definitions require that a >>client keep track of the set of activities to be monitored and >>controlled. That's a big burden to place on the client. >> >>I suggest (as we have also suggested in earlier communications to BES-WG) >>that we should instead allow the user to specify a set of activities that >>are to be monitored or controlled in terms of their properties, not >>names.

Meeting notes from Dec. 8th
by Darren Pulsipher 08 Dec '05

08 Dec '05

Attendees Darren (Maybe) William (Attending) Andrew (Attending) Steve N (Attending) Mark (Attending) Michel Agenda - WS-Name and/or EPR issue resolved. - We need to make sure the document has just EPRs and only mention the WS-Name as a return value from createActivity. All other parameters need to be EPRs. - The EPR that is returned does not have specified port types we have decided to push this until later. - We need to add to the spec "The createActivityFromJSDL MUST return a EPR (which is an endpoint reference) MAYBE a WS-NAME." - Meta-Data/Attributes on the container service - There is an abstract idea about information and operations. Example of ByteIO was brought up. We just say that there are pieces of information (Meta-Data) that the renderings should supply operations to get the information. We need to introduce this better in the document. We need to have a section under the service container called attributes that will have this information. Use UML nomenclature. - UK meeting next week (BES and SAGA interop) - Venue - William Penny hall - imperial college. Wireless is available - Monday - Starting 0900 - BES - Saga - Afternoon early evening -Tuesday - Starting 0900 - Naming - ByteIO -Wednesday - ??? - Section 5 needs to be cleaned up - Subscribing to events. We added a general statement about subscribing events. Add attribute to state whether or not it can handle events. We need to look at all SHOULDs and put an attribute in the container specifying whether or not it can handle the SHOULD. - Mark and William are working on the rendering and schemas. This will be discussed at the face to face.
