For working together, a common base is needed. Standards are defined, but often, they are not for free.
The thought of "open source software" is a good thing, giving a quick exchange to people with the same goal.
This page is intended for people who want to define a working base to collaborate with others, without consortiums, patents or other barriers.
If you have a good definition for working together, for example electrical interface definitions so that students from different universities can exchange their work, you are invited to place it here.
