The [http://www.gnu.org/philosophy/free-sw.html Free Software Definition] describes the four software freedoms:

* The '''freedom to run''' the program as you wish, for any purpose.
* The '''freedom to study''' how the program works, and change it so it does your computing as you wish. Access to the source code is a precondition for this.
* The '''freedom to redistribute copies''' so you can help others.
* The '''freedom to distribute copies of your modified versions''' to others. By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

Replimat seeks to extend the paradigm of [https://en.wikipedia.org/wiki/Free_and_open-source_software Free, Libre, and Open Source Software] into [https://en.wikipedia.org/wiki/Open-source_hardware Open Hardware] and the [https://en.wikipedia.org/wiki/Open-design_movement open design movement] by applying the four software freedoms to physical goods and processes.  Re-contextualized around physical goods, the freedoms become:

* The '''freedom to use'''. Run or otherwise execute the software, product, or process.
* The '''freedom to inspect''' or view how the object functions in the preferred format for making changes. This stems from the freedom to study how the program works, and change it to make it do what you wish. Access to the source code such as CAD files, text documents, spreadsheets, calculations, instructions, etc. is a necessary prerequisite for making substantive changes.
* The '''freedom to modify'''. This is a big point: making improvements or adaptation is a key to distributing value.
* Economic freedom. The '''freedom to sell'''. Freedom distribute copies of your modified versions to others. By doing this you can give the whole community a chance to benefit from your changes. Access to the source code is a precondition for this.

The four essential freedoms enable the fundamental creative processes: '''copying''', '''transformation''', and '''combination''' as outlined in Everything is a Remix:
