For unsupported videos we recommend converting them to mp4 using the open source application HandBrake, available for Windows, Linux and MacOS platforms at Choose the default "Fast 1080p30" preset, then in the Video tab choose "Constant Framerate". If you cannot or do not want to install software on your computer, you can use a web-based converter such as Cloud Convert. To create image stacks we recommend the Online Converter website.

This page is an educational resource for government employees and government contractors to understand the policies and legal issues relating to the use of open source software (OSS) in the United States Department of Defense (DoD). The information on this page does not constitute legal advice and any legal questions relating to specific situations should be referred to legal counsel. References to specific products or organizations are for information only, and do not constitute an endorsement of the product/company.


Careful legal review is required to determine if a given license is really an open source software license. The following organizations examine licenses; licenses should pass at least the first two industry review processes, and preferably all of them, else they have a greatly heightened risk of not being an open source software license:


In practice, nearly all open source software is released under one of a very few licenses that are known to meet this definition. These licenses include the MIT license, revised BSD license (and its 2-clause variant), the Apache 2.0 license, the GNU Lesser General Public License (LGPL) versions 2.1 or 3, and the GNU General Public License (GPL) versions 2 or 3. Using a standard license simplifies collaboration and eliminates many legal analysis costs.


It is important to understand that open source software is commercial software, because there are many laws, regulations, policies, and so on regarding commercial software. Failing to understand that open source software is commercial software would result in failing to follow the laws, regulations, policies, and so on regarding commercial software.


An agency that failed to consider open source software, and instead only considered proprietary software, would fail to comply with these laws, because it would unjustifiably exclude a significant part of the commercial market. This is particularly the case where future modifications by the U.S. government may be necessary, since OSS by definition permits modification.


In the DoD, the GIG Technical Guidance Federation is a useful resource for identifying recommended standards (which tend to be open standards). The GTG-F is a collection of web-based applications supporting the continuing evolution of the Department of Defense (DoD) Information Technology Standards. The DDR&E, Advanced Capabilities Modular Open Systems Approach web page also provides some useful background.


Many DoD capabilities are accessible via web browsers using open standards such as TCP/IP, HTTP, and HTML; in such cases, it is relatively easy to use or switch to open source software implementations (since the platforms used to implement the client or server become less relevant). As noted by the OSJTF definition for open systems, be sure to test such systems with more than one web browser (e.g., Google Chrome, Microsoft Edge and Firefox), to reduce the risk of vendor lock-in.


Software licenses, including those for open source software, are typically based on copyright law. Under U.S. copyright law, users must have permission (i.e. a license) from the copyright holder(s) before they can obtain a copy of software to run on their system(s). Authors of a creative work, or their employer, normally receive the copyright once the work is in a fixed form (e.g., written/typed). Others can obtain permission to use a copyrighted work by obtaining a license from the copyright holder. Typically, obtaining rights granted by the license can only be obtained when the requestor agrees to certain conditions. For example, users of proprietary software must typically pay for a license to use a copy or copies. Open source software licenses grant more rights than proprietary software licenses, but they are still conditional licenses that require the user to obey certain terms.


Computer and electronic hardware that is designed in the same fashion as open source software (OSS) is sometimes termed open source hardware. The term has primarily been used to reflect the free release of information about the hardware design, such as schematics, bill of materials and PCB layout data, or its representation in a hardware description language (HDL), often with the use of open source software to drive the hardware.


Intellipedia is implemented using MediaWiki, the open source software developed to implement Wikipedia. This Open Source Software FAQ was originally developed on Intellipedia, using a variety of web browsers including Mozilla Firefox. Thus, even this FAQ was developed using open source software.


Be sure to consider total cost of ownership (TCO), not just initial download costs. Even if OSS has no cost to download, there is still a cost for OSS due to installation, support, and so on (whether done in-house or through external organizations). Be sure to consider such costs over a period of time (typically the lifetime of the system including its upgrades), and use the same period when evaluating alternatives; otherwise, one-time costs (such as costs to transition from an existing proprietary system) can lead to erroneous conclusions. Include upgrade/maintenance costs, including indirect costs (such as hardware replacement if necessary to run updated software), in the TCO. By definition, open source software provides more rights to users than proprietary software (at least in terms of use, modification, and distribution). That said, other factors may be more important for a given circumstance.


Clearly, classified software cannot be released back to the public as open source software. However, often software can be split into various components, some of which are classified and some of which are not, and it is to these unclassified portions that this text addresses.


Government employees may also modify existing open source software. If some portion of the software is protected by copyright, then the combined software work can be released under a copyright license. (See next question.)


If the contractor was required to transfer copyright to the government for works produced under contract (e.g., because the FAR 52.227-17 or DFARS 252.227-7020 clauses apply to it), then the government can release the software as open source software, because the government owns the copyright. The NASA FAR Supplement (NFS) 1852.227-14 gives NASA the right, under typical conditions, to demand that a contractor assert copyright and then assign the copyright to the government, which would again give the government the right to release the software as open source software.


If the intent of a contract is to develop software to be released as open source software, it is best to expressly include release as OSS as part of the contract. This makes the expectations clear to all parties, which may be especially important as personnel change.


OTD is an approach to software/system development in which developers (in multiple organizations) collaboratively develop and maintain software or a system in a decentralized fashion. OTD depends on open standards and interfaces, open source software and designs, collaborative and distributed online tools, and technological agility.


To be honest, it literally feels like open source software is an anomaly in this tech-dominated world. The thought that a community of developers are so comfortable working on a single piece of software for years without money is absolutely mindblowing.


On the contrary, everything is flexible with open-source software. Anybody can modify it according to their specific needs. A great example of this is Drupal; it has been adopted by universities, cities, towns, and even the White House.


A community of experts is behind the constant development of open-source software. They give utmost importance to freedom and want the software to become efficient enough to be utilized by anyone with access.


PHP stands for hypertext pre-processor. It is a scripting language used mainly for web development. The plus point is that it can be embedded into HTML. It is said to be the best open-source software example.


Brave is a privacy-focused open-source browser developed by Brave Software. The feature that differentiates it from other browsers is that in the default settings Brave Browser automatically blocks online ads and website trackers.


Ruby on Rails is the most popular open source software and is built with the Ruby programming language. It is a tool that gives web developers a framework to give structure to the code that they write.


FileZilla is an open-source File Transfer Protocol application. It is a professional tool primarily used for sending files. It is among the many professional open source software examples primarily used for sending files.


Marketcetera is an algorithmic trading platform and gives the user complete control over the trading platform. It uses ACTIV Financial data steam services for data feed and uses the open-source library QuickFix. This software is specifically made for traders, financial firms.


This software is free, open-source and as such, its development is only possible because it is funded by different organizations. Among these, members of EDRLab, private or public grants and small recurring donations from happy users (individuals or companies).


Thorium Reader is based on the set of open-source chrome-less modules, a toolkit named Readium Desktop. Thorium Reader and Readium Desktop both rely on Electron.js, node.js and typescript, which are efficient cross-platform technologies. Thorium is also using React components based on HTML 5/CSS 3.


Your software is assembled as well as created. It includes more than open source and proprietary code. To build software users can trust, you must address the security of everything that goes into it.
