OW2 is a global open-source software community which goal is the development of open-source distributed middleware, in the form of flexible and adaptable components. These components range from specific software frameworks and protocols to integrated platforms. OW2 developments follow a component-based approach.

The consortium is an independent non-profit organization open to companies, institutions and individuals.

OW2 mission is to develop open source code middleware and to foster a vibrant community and business ecosystem.

OW2 is committed to growing a community of open source code developers. The organization is dedicated to the creation of new technology: original code development is one of its fundamental characteristics. As the organization becomes part of the open source marketplace, it also stresses the quality and market usability of its software. It fosters a common technical architecture to be shared by its members and to facilitate the implementation of its technology by systems integrators and end-users.

The OW2 projects aim at facilitating the development, deployment and management of distributed applications with a focus on open source middleware and related development and management tools. In the open source software value chain, OW2 is positioned as an industry platform facilitating interaction between open source code Producers and open source code Consumers.
