OWF started as a project at a single US Government agency, but developed into a collaborative project spanning multiple federal agencies. Overall project direction is managed by "The OWF Government Open Source Software Board"; i.e. what features should the core team work on next, what patches should get accepted, etc. Gov't agencies wishing to be represented on the board should check for more details. Membership on the board is currently limited to Government agencies that are using OWF and have demonstrated willingness to invest their own energy and resources into developing it as a shared resource of the community. At this time, the board is not considering membership for entities that are not US Government Agencies, but we would be willing to discuss proposals.



Contributions to the baseline project from outside the US Federal Government should be submitted as a pull request to the core project on GitHub. Before patches will be accepted by the core project, contributors have a signed Contributor License Agreement on file with the core team. If you or your company wish your copyright in your contribution to be annotated in the project documentation (such as this README), then your pull request should include that annotation.


Contributions from government agencies do not need to have a CLA on file, but do require verification that the government has unlimited rights to the contribution. An email to is sufficient, stating that the contribution was developed by an employee of the United States Government in the course of his or her duties. Alternatively, if the contribution was developed by a contractor, the email should provide the name of the Contractor, Contract number, and an assertion that the contract included the standard "Unlimited rights" clause specified by DFARS 252.227.7014 "Rights in noncommercial computer software and noncommercial computer software documentation".

Government agencies are encouraged to submit contributions as pull requests on GitHub. If your agency cannot use GitHub, contributions can be emailed as patches to


There is work underway to re-factor OWF to use OSGi on the back end, and eliminate the dependency on Ext JS for the front-end. As part of this work, Ozone Metrics will become a module in this new architecture. Multiple alphas have been released, and announced on ozoneplatform-announce. Although we initially intended a release for June 2013, we're revisiting our design to make sure it is fully scalable and enterprise-ready, both for OWF itself and for other capabilities built on top of the services of what we're calling ozoneplatform. Watch ozoneplatform-announce for further information as to specific timelines and availability of alphas.
