I am a committer on the Eclipse Process Framework (EPF) open source project. The code and content that makes up EPF was donated from the Rational Method Composer product and the Rational Unified Process. The open source version of RUP is called BUP, which stands for Basic Unified Process. Today you can download EPF Composer from the web site and begin authoring your own method content and publishing process configurations, or you can use the BUP method content and customize it for your own development project. There is also a published version of BUP available for download as well. EPF Composer and the published BUP web site are available from the EPF download page.
