OW2's key values are: Openness, Trust, Fairness, Transparency and Independence.

OW2 aims at leveraging open source to foster collaborative innovation and create value by sharing expertise, experience, and opportunities. The community is positioned in the open source value chain as a platform aimed at connecting producers of code and that code's respective users.

Open source projects are collaborative by nature; OW2 offers projects and contributors a neutral environment where they can work together independently of private interests.


OW2 is dedicated to developing open source code infrastructure and to fostering a vibrant community and business ecosystem.

OW2 offers three kind of services :

1) Technical infrastructure:

OW2 provides developers with state-of-the-art technical infrastructure, offering project hosting and providing a number of services to facilitate the collaborative work (versioning, bug tracking, licenses, etc.).

2) Community Services:

OW2 offers a platform dedicated to connecting members with each other and with the international open source ecosystem at large.

3) Marketing Services:

OW2 develops brand awareness and promotes its code base, offering high levels of visibility for its projects and members with many industrial conferences and tradeshows.

OW2 provides in addition information dissemination and community building services to R&D collaborative projects funded by European or French research programs.

The activities[edit]

The Code Base: OW2 hosts some 100 open source Projects spanning enterprise solutions and components, application frameworks, engineering tools, and libraries.

The Initiatives: Several of these projects are combined into market-driven Initiatives which facilitate their implementations into business solutions by systems integrators, OEMs, and end-users.

List of OW2 initiatives launched from OW2 creation:

  • Open Source in Big Cities
  • Accessibility
  • Security
  • Future internet
  • Cloud Computing
  • Big Data
  • Business Intelligence
  • SOA
  • e-government


OW2con is the OW2 Consortium's annual community conference. OW2con aims to bring the OW2 community, project managers, decision-makers, technology experts, and more together for two days of keynote addresses, round table discussions, and speaker presentations about the open source world and environment.

Traditionally held in Paris, the goal of OW2con is to expand OW2's influence and reach in the open source world by creating a stronger community, increasing visibility, and educating the public about the possibilities and future of open source software.
