This technical report focuses on setting the basis for an open approach for evolution, maintenance and administration of OMM (Qualipso Open Source Maturity Model). We define a collaborative and distributed strategy and platform to support these perspectives. Such open collaborative platform is designed to support comments, discussion and evolution of the OMM. OMM is a CMMI-like model [4] for FLOSS (Free and open source software) that can be implemented in software organizations to enable FLOSS usage both in production and development of software products. The more OMM is used the more improve opportunities to the model will show up. Handling such improvements is essential to keep the model updated and alive.
