There is this really beautiful algorithm implemented behind really oldschool JS that I have seen used a couple times: WebGME. https://github.com/webgme/webgme https://github.com/webgme/webgme It is a Model-Based-Systems-Engineering tool, as far as I can tell, and it lets you create "metamodels" (SysML diagrams / rules essentially) and then collaboratively author some model graph, giving you a "commit" for every action, a version history, a git-like branching and merging model, and more. The collaborative aspect is pretty strong in their own UI, I've tried to build my own and couldn't get it as easily, but I guess my question is: has anyone ever used this tool as well?
