By providing access to relevant, open source engineering software tools, using input provided by both Appropedia contributors and the wider OSAT engineering community. We aim to both provide information on existing tools and identify areas in which new tools would be of use so as to encourage the development of such tools.

For tools that are available, our goal is to provide reviews regarding the usefulness of each tool for particular applications, guides on how to most effectively use the tools for various types of efforts related to space system development, and descriptions of how the tools can be used together. Where needs exist to either create new tools or enhance existing tools, we will aim to gather input regarding what functionality is desired and (when possible) point towards relevant commercial tools that could serve as models.

While the focus of this project is on tools that are relevant to sustainable development applications there is significant overlap with many other engineering disciplines, as such a significant number of the tools we describe will be relevant outside of the appropriate technology arena.

Please help this project and the sustainable development engineering community as a whole by expanding the material available here.

Software Licenses

For the purposes of this project, we are interested in identifying software tools that are free and open source in the sense that the software's source code is provided and the software license allows you to use, modify, and freely redistribute the software without paying royalties or other fees. Software included here should meet the Open Source Definition of the Open Source Iniative (OSI) and the Free Software Definition of the Free Software Foundation (FSF) (where free means freedom).

OSI maintains a list of software they have approved here. FSF has a listing of software free and non-free software licenses here. The FSF listing also specifies whether the license is compatible with the GNU General Public License (GPL), a leading open source license.

Engineers who have great experiences can gain online life experience degree which will allow them to help other engineers through open source engineering software.
