I am going to create a version of the IFRS Fundamental Accounting Concept Relations metadata on GitHub to check out how that works. This will include the reporting styles, mapping rules, impute rules, and consistency checks.
If you are not familiar with GitHub, create an account (which is free) and work throught this tutorial. That will get you started.
Here is my initial repository: fac-ifrs (master)
I have someone helping me get started. I am going to keep the same technical syntax in this version. The files will simply be pulled from this GitHub location and people will be able to contribute, branch, etc. using the GitHub functionallity.
There are great videos on how to use GitHub.
Another alternative to GitHub is BitBucket. The good thing is that there are alternatives. Now, I have to figure how which is better, GitHub or BitBucket.
