The General Services Administration develops digital solutions for internal operations and to help agencies meet the needs of the people and businesses they serve. This requires flexibility in how we code, with a focus on lowering costs for the American people, while improving their interactions with the U.S. Government.
GSA's official Open Source Policy specifies internal guidance to move GSA to an "open first" posture. The narrative here compliments the policy and provides rationale for doing so.
The default position of GSA when developing new projects is to:
- Use Free and Open Source Software (FOSS), which is software that does not charge users a purchase or licensing fee for modifying or redistributing the source code, in our projects and contribute back to the open source community.
- Develop our work in the open when possible with default leaning towards "open first".
- Publish source code publicly whether it was created or modified by GSA, either by in-house by government staff or contractors.
- Utilize contracts and contract language to capture and publish custom code.
Using FOSS allows for product customization, advances interoperability between tools, and improves the overall quality of the final product. Other benefits include:
-
Flexible usage. The benefits of using FOSS compels GSA to meet user needs by modifying existing or creating new FOSS. FOSS is particularly suitable for rapid prototyping and experimentation. The testing process generates minimal costs, and the process encourages the identification and elimination of defects not recognized by the original development team.
-
Community involvement. Publicly available source code enables continuous and broad peer review. Whether simply publishing the completed code or opening the development process, the practice of expanding the review and testing process to a wider audience—beyond the development team—ensures increased software reliability and security. Developing in the open also allows for other opinions to help adjust the direction of a product to maximize its usefulness to the community it serves.
-
Cost-savings. The ability to modify FOSS enables GSA to respond rapidly to changing missions and markets. Support and maintenance of open source code—as opposed to more burdensome usages of proprietary software—provides a real cost advantage where multiple copies of software are required, or when the user base grows. The total cost of ownership is shared with a community, rather than solely GSA.
-
Reusability. The code we create belongs to the public as a part of the public domain. The code we work on was paid for by the American people, but the end-product is not the only way they should be able to interact with their government. By coding in FOSS, we help populate a larger commons that cities, states, businesses, and individuals can participate in. This creates real economic value by lowering the burden of replicating similar work or by allowing the private sector to build off of and create new businesses around code developed at GSA.
Active involvement from the open source community is integral to the success of open source code. GSA will be an active contributor to FOSS projects that it or its clients utilize.
Code written entirely by GSA staff, where possible, will be dedicated to the public domain. In addition, any contracts GSA enters into, where others will develop software on GSA's behalf, will ensure that most results are dedicated to the public domain.
GSA encourages contributions to its open source projects, whether it be code, commentary, bug reports, feature requests, or overall strategic direction.
Forks or clones of our code repositories are free to be re-distributed. This means code created by GSA can be integrated into work that is under a more restrictive license, even those that are not considered open source licenses.
This changes when our code repositories include code that was not created by GSA and carries an open license. Code previously released under an open source license and then modified by GSA or its contractors is considered a ["joint work"] 4 and must be released under terms permitted by the original open source license.
The public can use our code as the basis of wholly proprietary and commercial systems. GSA would appreciate that users of our code disclose its lineage, but GSA maintains no legal right to require disclosure. Notifications that our work is used in a new system are always greatly appreciated.
As previously mentioned, most work generated at GSA falls within the U.S. public domain.
For our international colleagues, GSA also permanently waives all copyright and related rights worldwide to code created by GSA or its contractors.
Our default LICENSE file for projects acknowledges that our work is in the US public domain, and uses CC0 to waive copyright internationally.
Our default CONTRIBUTING file informs contributors that their contributions will be licensed under the same terms.
However, certain projects will require the usage of licensed open source software not created by GSA. Some open source licenses make source code available under different terms and conditions. These terms and conditions specify how the code may be used, modified, or shared. When users modify GSA code, they should review and understand the terms of the open source license in question.
Each project may need to modify or extend the above LICENSE and CONTRIBUTING files as needed for its own circumstances.
There is a misconception that FOSS that is distributed to the public should not be integrated or modified for use in sensitive systems. On the contrary, FOSS is often preferred for use in sensitive systems, due in part to its increased auditability. In other words, security in FOSS must be designed never to rely on obscurity in how the code works.
In addition, while open source licenses permit the user to modify FOSS for internal use without obligating them to distribute source code to the public, when the user chooses to distribute the modified FOSS outside the user's organization, then the code is subject to whatever license it carries.
The only conditions where code shall not be developed and released in the open are:
-
The U.S. Government does not have the rights to reproduce and release the item.
-
The public release of the item is restricted by other law or regulation, such as the Export Administration Regulations or the International Traffic in Arms Regulation.
These decisions will be made as needed by the GSA, which will lead an interdisciplinary team to review the conditions under which code will not be made available publicly.
If an existing solution cannot be found in the open source community, GSA may consider other options, including creating an open source solution itself. Ultimately, the software that best meets the needs and mission of GSA should be used.
OMB M-16-21 - A White House policy pertaining to federal source code, published by the White House Office of Management and Budget. M-16-21 directs all agencies to publish some custom developed code as open source code, to update acquisition requirements to capture code developed by vendors for GSA, and to inventory all open- and closed-source code.
The GSA CTO's Digital Service Division, author of this page/repo, would like to thank the 18F, Consumer Financial Protection Bureau, Department of Defense, and Office of Management and Budget for their work in blazing the path for the use of FOSS in the Federal Government.
