OZONE Widget Framework


The OZONE Widget Framework (OWF) is a framework that allows data from different servers to communicate inside a browser window without sending information back to the respective servers. This unique capability allows the OWF web portal to offer decentralized data manipulation. It includes a secure, in-browser, pub-sub eventing system which allows widgets from different domains to share information. The combination of decentralized content and in-browser messaging makes OWF particularly suited for large distributed enterprises with legacy stovepipes that need to combine capability. Use it to quickly link applications and make composite tools.

Desktop Layout

Desktop Layout

This is a desktop layout. Users can move widgets to useful locations on the screen.

Tabbed Layout

Tabbed Layout

Tabbed layouts allow widgets to open on separate tabs.

Using the App Builder, users can design dashboards that incorporate multiple layouts. You see desktop and tabbed layout examples above. You can also incorporate accordion, portal and fit-pane layouts into each dashboard.

Technology components

For OWF Version 7.16.0, the front-end user interface uses JavaScript, and the back-end uses Grails. User preferences are stored in a relational database - anything supported by Hibernate. Authentication of users is a modular function provided by Spring Security.

Browser Support

Numbered releases are tested on IE7, IE9, Firefox 17 and Chrome 33.

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, contributions are reviewed by the core team, see Contributor Guidelines. 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
