This repo has recently undergone a major reorganization, to make it easier for you to understand and contribute to. The previous version, which contains a lot of dormant unmigrated stuff, is here.
What I'd like to see is legal contracts written up in a kind of code similar to computer code; something that can be checked for validity, evaluated, perhaps even unit tested. We could perhaps generate natural language descriptions of the code in varying complexity (maybe even generate legalese, which could be useful if you're using the code to create custom contracts), or it could be accurately visualized in some way. My fear is that in writing such code to deal with real-world issues, you'd also need a model of the real world, and that would be incredibly hard to define.

L4 is the strongest domain-specific language for writing such code. It builds on 70 years of academic work in computational law.
