All, I have read the document Moreno provided very carefully and have a large number of comments that I will share when we discuss the document morning/afternoon. First, thank you Moreno for putting "on paper". My high level comments are: 1) I that I feel it is important to clearly separate requirements from mechanism in the first discussion. There many ways to solve a problem. 2) That minimalism in composable porttypes leads to cleaner design. In particular, it might make sense to define a simple ActivityEndpoint porttype that provides information for example on uri's to access the execution directory for staging, etc. To quote another European "Perfection is achieved, not when there is nothing more to add, but when there is nothing left to take away." Antoine de Saint-Exupery 3) The differences from the current BES are pretty minor, e.g., vectorization of create and change state. As an aside, our experience with the current BES specification is that passing back the list of activities "contained" by a BES resource is awkward at best, and a performance inhibitor at worst. A direct call to get the instances makes much more sense. They way we have done this -- that does not require any new specification is via the use of the RNS porttype to "list" activities. Andrew Ps. Moreno, it might be useful if you used a screen sharing software such as glance while going through the document.
