Tracy,
Yes, we discussed it and we think it should move forward. As you suggest in your email, we think Jonah and Peter would be good co-project leads. We would like to see this project contain the IDataSet packages, the data structures packages from ICE and the data structures from EAVP so that we start building a single data structures project for Science. (N.B. - the initial contribution for EAVP hasn't been added to the repo yet.)
The list of committers will need to include people from all three of those projects as well as any others that want to add to the initial contribution.
Although we like the idea of contributing to the Collections project, we felt that the scope of work for this project was different enough that it warranted its own project.
One possible future direction that we discussed which interests Greg and I quite a bit is figuring out how we can make these data structures architecturally aware so that for very large data sets the work can be processed on multiple cores or a GPU.
I forget what we thought the name should be.
Greg and Torkild, what did I miss from our discussion? Matt please chime in too since you weren't at the meeting.
