Standards for Open Source Software
Business Readiness Rating (BRR) is a proposed standard for rating open source software. This project is led by Carnegie Mellon West Center for Open Source Investigation, O’Reilly CodeZoo, SpikeSource, and Intel.
From the website:
The ultimate goal of BRR is to give companies a trusted, unbiased source for determining whether the open source software they are considering is mature enough to adopt. It will help adopters assess which open source software is best suited to their needs and enable them to share findings with the community. It promotes use and adoption of open source software and may assist developers in creating and delivering software geared to enterprise use.
