I've contributed to this project, and for me this seemed solved. I think almost everything is open now: Their website: https://github.com/openmensa/openmensa Their library: https://github.com/mswart/pyopenmensa The parser they use are decentralized. The software to build such a parser server is their pyopenmensa library. Their protocoll is also well documented: http://doc.openmensa.org/
An example of some of the available parsers: https://github.com/mswart/openmensa-parsers
