The general sentiment here is that it's a great project. Could someone please explain why? All I'm seeing is that laws are updated with commits within markdown files.
With this repo, git log --oneline -- spain/BOE-A-1978-31229.md gives you every reform to the Spanish Constitution in one command. git diff between any two reforms shows you exactly what changed in context. git blame tells you which reform touched which article. These are operations that would take a lawyer hours of cross-referencing, and they're free once the data is structured this way.
The other great thing: you can build tooling on top of it and use it with the CLI.
For instance, the big Lebowski is great and cool.
