Roadmap (All authors)
=====================
After determining work assignments, development begins by creating a
prototype. Developers will endeavor to build an API for the prototype be
that can be carried forward into production. Early work should include
the authentication system, and framework for the web interface. Back end
functionality will be divided up into REST API accessible portions, and
a separate, server-only functional (or class) API. Database schema will
develop at this time as well.
All development needs to be test driven, with some way to determine if
the code is behaving properly. This is especially important for the
authentication module, and all data-processing pipelines.
A tight timeline for the prototype is 2 months. During prototyping we
try out ideas, and discover any discrepancies in the functional plan. At
the end of the prototype phase we allow a week or two where we evaluate
which parts of the APIs to retain, and which to rewrite.
Real project development will proceed based on priority of end user
needs, with some input from developers about fundamental functionality
for the API foundations.
Milestones (All authors)
========================
Need something firm for the July meeting (Tom, Rachael, based on CPP
proposal)
