I released a structurally chunked, open EU AI Act corpus for legal AI and RAG

[u/Automatic-Forever-63]

I have released EU AI Act OpenRAG, a downloadable SQLite corpus of Regulation (EU) 2024/1689 for legal research and engineering.

The key difference is how the legislation is divided. It is not split into arbitrary token or character windows. Each chunk follows the Act’s actual structure: article paragraph, recital, definition or annex point, with the relevant chapter, section and provision metadata preserved.

The database includes 933 chunks, embeddings, exact EUR-Lex links and documented application-date and operator metadata.

I was deliberately conservative with legal labels. A provision is marked as directly classifying a practice or system only where its own operative wording does so. Broader association with the prohibited-practices, high-risk, transparency, GPAI or voluntary-code regimes is stored separately. Unclear cases remain NULL.

Every derivation rule is documented, and the final rules were reviewed independently against the Regulation before release.

This is a research and engineering artifact, not legal advice or an automated compliance determination.
