I would like to learn more about XDNA Foundation. It is stated that its non-commercial. I tried to find something else, but it is quite hard.. Is there any other information about it?
Details present in the OP and the website of XDNA project.
You should spend your time to visit these places and discover yourself for what you wanted.
I would say that it is better to first read Whitepaper where are all the specifications and where I can get details about all aspects of XDNA project
