A "process engineering framework" from the Eclipse Foundation, based in part on a donation part of the Rational Unified Process by IBM. The project currently provides a software component for process engineering and a minimal methodology, OpenUP.
So far as I can tell, the part of RUP exposed includes the process framework, but not the RUP roles, work products, et cetera. Manifest products of the projects are the EPF Composer, which is an Eclipse Ide based tool for using the framework to create a process; and OpenUP (Wiki Word?) a very slim variant of the Unified Software Development Process, provided partly as a library for the composer. "Process libraries" for other methodologies are provided, including descriptions of Extreme Programming, Scrum Methodology, and soon OpenUP/Basic (Wiki Word?).
OpenUP and OpenUP/Basic are quite svelte considering the reference to RUP. OpenUP has 6 roles and 17 work products. OpenUP/Basic is under preparation but interests me more than OpenUP because the architect has explicit coding duties (see Architects Dont Code). Whoops - that must only be an old version of OpenUP/Basic. The current version has just the "Architect Handbook" work product.
