Charter:

Scope & Objectives

The new PCDM-based Hydra architecture — the Hydra::PCDM / Hydra::Works / CurationConcerns / Sufia stack (AKA “The Gobstopper”) —  is now a year old, and needs to be evaluated in order to reach its next level of maturity. The scope of each gem and the distribution of features across this set of gems and their dependencies is a frequent topic of discussion among developers and stakeholders, and concerns around whether our stack has become too granular to maintain have also emerged: does our stack strike the right balance between architectural concerns and maintenance and other concerns, and if not, how ought it to change?

Questions about what the APIs and interfaces between the gems should be have also surfaced. This is a logical follow-on topic as we consider the scope and maturity of each gem, but should also help us to establish some best practices and reference patterns for developers of new or existing Hydra applications (e.g. Avalon, HydraDAM) who wish to build new applications upon or migrate existing applications to CurationConcerns or Sufia.

This group should be comprised of a balance of no more than ten architects, developers, and concerned managers/strategists who are using or aspire to use this application stack, who share and have opinions about these matters, and who can commit to the following deliverables and timeframe.

Deliverables & Timeframe

Deliverables will include:

These documents will be delivered via the Hydra wiki.

While the timeframe will ultimately depend on the members, drafts of the deliverables should be available for presentation at Hydra Connect 2016 (first week of October).

The group's sunset date is currently scheduled for November 1st, 2016.
