enriquelopI put all 8,642 Spanish laws in Git – every reform is a commit
I built a pipeline that converts all Spanish state legislation into version-controlled Markdown. Each law is a file, each reform is a real git commit with the historical date. 8,642 laws, 27,866 commits.
The idea: legislation is just patches on patches on patches. Git already solves this. Instead of reading "strike paragraph 3 and replace with...", you get an actual diff.
The repo is the product. Browse any law, git log to see its full reform history, git diff to see exactly what changed.
Built the pipeline in ~4 hours with Claude Code. Source is BOE (Spain's official gazette) consolidated legislation API.
Exploring whether there's a business here — structured legislation API for legaltech/compliance, or just a useful open dataset. Curious what HN would build with this data.
Oooh Can you elaborate a bit how the gazette is publishing them? Like what format did you have to parse. And how many documents were there in total? I tried doing the same for German laws 1-2 years ago but LLMs weren't smart enough yet. And the costs would've been at least a couple of thousand €.
Ed: Nevermind, I missed the "BOE (Spain's official gazette) consolidated legislation API" part. Sending jealous greetings from Germany. We just have a bunch of PDFs in Germany. And the private entity that has been publishing them for decades even claims copyright on them!
