Hi, I'd like to do some more on the BES spec. However, I have a few questions that I want to raise first: * The extensible state model: this seems a great idea. However, I feel concerned that there are difficulties lurking there that we haven't discovered yet. Is there any prior work here that we can refer to in order to make ourselves (and others) feel more confident in the approach? * Information model: I certainly think we need an information model. On the other hand, I wonder if we might want to think about pulling the details out as a "profile." What we have is just what we need for our current HPC use cases; on the other hand, if one is modeling say a Java container, they might be less appropriate. Thoughts? * Management operations: we currently have a couple of operations ("start/stop accepting requests") that are really container management rather than job operations. Could we separate those out in a distinct port-type? * I know there was discussion about how to handle single-job vs. multi-job operations in a consistent manner, but I don't know how that was reconciled. Ian.
