Data, modeling, and software developed by government employees are considered public domain. Therefore, these tools are free, open, and available to all. To accomplish this goal, CDRH and the Office of Science and Engineering Laboratories (OSEL) advocate that developers publish and maintain these tools in web-accessible repositories. To promote the visibility and transparency of computational research, developers are also encouraged to release early and often in accordance with open source software development philosophy. This approach creates a tight feedback loop between software developers and testers/users, expediting the development of higher quality software.
The following computational research projects contain tools available through external software repositories:
