The OpenSolaris Community Advisory Board (CAB) was composed of 5 members -- 2 from Sun, 2 from the OpenSolaris pilot community, and 1 from the open source community. The CAB was created to develop an OpenSolaris Charter and Governance and to drive consensus within the community.
With the approval of the OpenSolaris Charter, the CAB actually became the first OpenSolaris Governing Board (OGB) until the March 2007 elections.
