The four freedoms from Free Software Definition lay the foundation for sharing hardware through OHANDA. The adaptations below are made by just replacing the term "program" with the term(s) "device /& design". This may not be the most understandable way of describing freedoms of sharing open hardware, but it describes the degree of openness OHANDA stands for. By granting these four freedoms for all documentation attached to a product, the sharing is on sustainable basis.
The freedom to use the device for any purpose.
The freedom to study how the device works and change it to make it to do what you wish. Access to the complete design is precondition to this.
Redistribute the device and/or design (remanufacture).
The freedom to improve the device and/or design, and release your improvements (and modified versions in general) to the public, so that the whole community benefits. Access to the complete design is precondition to this.
