This page serves as an index for various design sketches, meeting minutes, and developer documentation pages produced as part of Gen3 Middleware (Gen3 Butler, SuperTask) development in S18 and F18.  Many of these were originally nested under the Data Butler Working Group page, but were not actually products of that working group.

None of these documents should serve as the final authoritative reference for any middleware components; all relevant content should eventually be migrated to LDM documents or at least technical notes.
