Clarifications:

We noticed at GGF5 that there was some confusion over the scope of the WG. It seemed that it would be helpful for us to make some clarifications to our scope. Following discussions (at meetings and on the list) since then, we have come up with some (hopefully helpful) statements:

• We are not working on a co-scheduler or super-scheduler, although the protocol could be used (as an enabling technology) by a co-scheduler.
• For now, GRAAP-WG will consider the reservation of timeslots on computational resources as the key use of the protocol. We hope, in time, that the protocol can be used for other resources, such as networks, but from a discussion at GGF6 we realised that there are complex issues regarding network reservation. Although we will try and be as general as possible, we cannot take all possible uses for the protocol into account.
• The group is not currently working on a Resource Description Language, and will not be for the near future. Our protocol will need to communicate in some RDL (or perhaps several), but we will wait and see if a suitable RDL emerges from the community. In the meantime, we may well produce some requirements for a suitable RDL.
