When a software application such as a spreadsheet is programmed under the umbrella of a project, the donor retains intellectual property (IP) rights. Hence, I decided that I was going to program the spreadsheet on my own free time in order to retain the IP rights himself. Once I had the first version ready, I relinquished it as a commons under a Creative Commons - Attribution, Non Commercial & Share-alike license.
In its present version, Prodegee is the result of those initial 200 hours of pro-bono programming, plus an extra 800 hours contributed through donor-funded projects. By making it Creative Commons with the clause Share Alike before any donor started funding its further development, I made sure that Prodegee remained freely available for anyone to use.
A commons is a cultural and natural resource accessible to all members of a society.
Creative Commons is a type of copyright licence that allows the owner of the IP to relinquish some of their inherent rights and reserve others.
The non-commercial clause prevents others from selling Prodegee. In this way I wants to guarantee that everyone can download the latest version for free, with funding going only towards the financing of time to add required features and improvements.
The share-alike clause means that any project willing to contribute with funding to improve Prodegee cannot change the fact that the spreadsheet is a commons. In this way, projects inherit the improvements funded by other projects, without having to finance each time a spreadsheet programmed from scratch.
