# ITU-T source mirror

This dataset mirrors the ITU Telecommunication Standardization Sector (ITU-T) Recommendations. Every source is kept twice: `original/` is the Recommendation as ITU-T released it (PDF), and `marked/` is that same document converted to Markdown for search and retrieval, one `raw.md` per document with any figures extracted beside it. The two trees share identical paths, so a file in `original/` has a parsed twin at the matching path under `marked/`; both are grouped by ITU-T Recommendation series, the single-letter folders A through Z. `manifest.jsonl` carries one row per file (path, SHA-256, parse status), and `STATUS.md` reports how much of the corpus has been parsed.
