+# LegalQuAD — RTEB open subset, unified schema
+
+A normalised copy of the dataset behind the `mteb` task **`LegalQuAD`**, one of the 17 open tasks in the
+[RTEB(beta)](https://huggingface.co/blog/rteb) retrieval benchmark. Same queries, documents and relevance
+judgements as the benchmark evaluates — reshaped into one strict schema shared by all 17.
+
+|  |  |
+|---|---|
+| Source | [`mteb/LegalQuAD`](https://huggingface.co/datasets/mteb/LegalQuAD/tree/37aa6cfb01d48960b0f8e3f17d6e3d99bf1ebc3e) @ `37aa6cfb01d4` (the revision pinned in `mteb`) |
+| Domain · languages | legal · deu |
+| Queries / documents / qrels | 200 / 200 / 200 |
+| Qrels per query | min 1 · mean 1.0 · max 1 |
+| Score values | 1 ×200 |
+| Layout | `queries` · `corpus` · `qrels`, split `test` |
+| License | `cc-by-4.0` |
+
+## Schema
+
+| config | columns | rules |
+|---|---|---|
+| `queries` | `id: string`, `text: string` | ids unique and non-empty; every query has ≥ 1 qrel |
+| `corpus` | `id: string`, `title: string`, `text: string` | `title` is always present (`""` when the source has none) |
+| `qrels` | `query-id: string`, `corpus-id: string`, `score: int32` | referential integrity to both tables; no duplicate pairs; no floats |
+
+Files are Parquet, sorted by id, zstd-compressed, sharded at 500 MB. Every rule above is enforced by a validator
+before publishing; `provenance.json` records the source file hashes, what changed, and the output file hashes.
+
+## What changed from the source
+
+- cast `qrels.score` double -> int32
+- removed NUL bytes from text (prose dataset)
+- renamed `_id` → `id`
+- renamed source splits (`queries`←`queries/queries`, `corpus`←`corpus/corpus`, `qrels`←`default/test`) to `test`
+
+## Load it
+
+```python
+from datasets import load_dataset
+queries = load_dataset("Hyukkyu/rteb-LegalQuAD", "queries", split="test")
+corpus  = load_dataset("Hyukkyu/rteb-LegalQuAD", "corpus", split="test")
+qrels   = load_dataset("Hyukkyu/rteb-LegalQuAD", "qrels", split="test")
+```
