OW2 consortium / Page 2


OW2 is an independent non-profit organization dedicated to the development and promotion of open source in the domains of middleware, generic business applications and cloud computing platforms. Orange is a founding and strategic member of OW2.

Thus, Orange is involved in the governance and the management of the OW2 consortium; Orange is the leader of the Open Source Accessibility initiative (OSAi) supported by OW2; Orange drives or contributes to several Open source projects hosted by OW2.

OW2, as a non-profit organisation, exists because of its Members . OW2’s budget comes mainly from the membership fees, and also from subsidies of collaborative projects  for which OW2 is a member (mainly in charge of dissemination).
