OW2 Intellectual Property Policy Primer

Unknown macro: work-in-progress.
A primer on OW2 IP management for project leaders.
Please check out the official OW2 IPR Policy for detailed informations.


IP Management

Intellectual Property management is a process used to handle IP issues.


Project must take care of their dependencies, in order to remain license compatible.
Each dependency of a project has its own license, project members have to make sure that they use the dependencies (linking, distribution, ...) within the bounds of the license.

For example, a LGPL3 project cannot depends on a GPL3 library (GPL3 is viral and requires 'client' to be GPL too).
Another example: a LGPL project has the right to depends on an ASL2 library.

Code Ownership

Project also have to manage code property, ensuring that its codebase remains clean from copyrighted, patented contributions.

If OW2 does not own the code, the contributor may keep its copyright, so contributions may be copyrighted, but it could be perfectly normal.
  • The code you commit in the project belongs to you (Author)
  • Copyright

OW2 Propositions

The OW2 Consortium do not own any copyright or claim code ownership on project's contributions.
OW2 only provides the infrastructure that hosts the code.

By default, the OW2 IP Rights Policy applies on contributions.

Per-Project Policy

  • Each project is responsible to handle IP cleanness in its own way
  • OW2 only provides guidance


All committers of a project should (must ?) have signed the OW2 Membership Agreement.

Contributor License Agreement

Source Headers

All project's source file (non-generated) must have a license header at the top.
The license header depends on the license selected by the project.


Software Grant Agreement

A Software Grant Agreement (SGA) may be required when a full working code base (like a sub-project, or a significant component) is willing to be contributed to a project.
