+# IATE 2016 — Inter-Active Terminology for Europe
+
+Tidy HuggingFace release of the **IATE** terminology export dump from **2016-04-25** (the snapshot in `iate.zip`). IATE is the official multilingual terminology database of the EU institutions and bodies — see <https://iate.europa.eu>, <https://iate.europa.eu/faq>, and <https://iate.europa.eu/download-iate>.
+
+This is the **2016 snapshot only**. IATE is continuously updated; for the latest dump pull from the official IATE download page.
+
+Mirror of the raw upstream zip: [`alvations/stash · iate/iate.zip`](https://huggingface.co/datasets/alvations/stash/tree/main/iate).
+
+## Configs
+
+| Config        | Rows       | Schema | Notes |
+| ------------- | ---------: | ------ | ----- |
+| `monolingual` | 6,148,883  | one row per `(term_id, lang)` entry | full multilingual TSV; spans all EU official languages (~24) |
+| `en-de`       |   546,974  | one row per aligned EN ↔ DE term pair | pre-aligned bilingual subset |
+| `en-fr`       |   730,779  | one row per aligned EN ↔ FR term pair | pre-aligned bilingual subset |
+| `en-fi`       |   226,688  | one row per aligned EN ↔ FI term pair | pre-aligned bilingual subset |
+| `en-cs`       |    13,524  | one row per aligned EN ↔ CS term pair | pre-aligned bilingual subset |
+
+The upstream zip also contained `iate_en-ru.csv` / `.json` but they were empty (header only) — skipped.
+
+## Usage
+
+```python
+from datasets import load_dataset
+
+# Full multilingual dump
+mono = load_dataset("alvations/iate-2016", "monolingual", split="train")
+print(mono[0])
+# {'term_id': 'IATE-14', 'lang': 'ro', 'term': 'Agenție de aprovizionare',
+#  'term_type': 'fullForm', 'reliability': 3}
+
+# Pre-aligned bilingual subsets (great as MT terminology gazetteers)
+en_de = load_dataset("alvations/iate-2016", "en-de", split="train")
+print(en_de[0])
+# {'term_id': 'IATE-84',
+#  'src_lang': 'en', 'src_term': 'competence of the Member States',
+#  'tgt_lang': 'de', 'tgt_term': 'Zuständigkeit der Mitgliedstaaten'}
+
+# Recover all language entries for a single term
+mono_df = mono.to_pandas()
+mono_df[mono_df["term_id"] == "IATE-84"]
+# 23 rows — one per EU official language
+```
+
+## Schemas
+
+### `monolingual`
+
+| Column        | Type   | Description |
+| ------------- | ------ | ----------- |
+| `term_id`     | string | IATE entry id, e.g. `"IATE-14"` |
+| `lang`        | string | ISO-639-1 code (`en`, `de`, `fr`, `bg`, `el`, …) |
+| `term`        | string | the term text in that language |
+| `term_type`   | string | upstream type label: most commonly `fullForm` (the canonical form); sometimes abbreviation / short-form variants |
+| `reliability` | int8   | reliability code, 1–5 (see "Reliability codes" below) |
+
+### `en-{de,fr,fi,cs}`
+
+| Column      | Type   | Description |
+| ----------- | ------ | ----------- |
+| `term_id`   | string | IATE entry id (same one shared across languages) |
+| `src_lang`  | string | always `"en"` |
+| `src_term`  | string | English term |
+| `tgt_lang`  | string | `"de"` / `"fr"` / `"fi"` / `"cs"` |
+| `tgt_term`  | string | target-language term |
+
+The 4 bilingual configs share one schema, so you can `concatenate_datasets([...])` them with a single column projection.
+
+## Reliability codes (IATE convention)
+
+| Code | Meaning |
+| ---: | ------- |
+| 1    | Not verified |
+| 2    | Minimum reliability |
+| 3    | Reliable (terminologist-checked) |
+| 4    | Very reliable |
+| 5    | Verified / institutional gold standard |
+
+Most rows in this snapshot carry code `3` (reliable).

+## Provenance
+
+- Upstream zip: `iate.zip` containing 12 files (1 monolingual TSV, 4 bilingual `.csv`/`.json` pairs for EN-DE/FR/FI/CS, plus empty EN-RU); 564 MB uncompressed, snapshot 2016-04-25.
+- Mirror: <https://huggingface.co/datasets/alvations/stash/tree/main/iate>
+- Conversion: stream-build via `zipfile` + pyarrow `ParquetWriter` (no on-disk extraction). The 321 MB master CSV is written in 200K-row batches.
+- Build script: `build.py` alongside this README.
