+# Cross-Border Legal Core (EU PIL Subset)
+
+A curated subset of **EU private international law provisions** used as the retrieval corpus for the [Cross-Border Legal RAG](https://huggingface.co/spaces/SehaanCuda/crossborder-legal-rag) system.
+
+> **Educational use only — Not legal advice.**
+
+---
+
+## What is in this dataset?
+
+Selected mandatory provisions from three foundational EU regulations governing choice-of-law and jurisdiction in cross-border civil and commercial matters:
+
+| Instrument | CELEX | Provisions Included |
+|---|---|---|
+| **Rome I** — Reg. (EC) No 593/2008 | 32008R0593 | Arts. 4, 6, 8 (sub-articles split) |
+| **Rome II** — Reg. (EC) No 864/2007 | 32007R0864 | Art. 4 (sub-articles split) |
+| **Brussels Ia** — Reg. (EU) No 1215/2012 | 32012R1215 | Art. 7(1), 7(2) |
+
+Each record corresponds to one meaningful sub-article chunk, optimised for dense retrieval (~150–250 tokens per chunk).
+
+---
+
+## Fields
+
+| Field | Type | Description |
+|---|---|---|
+| `id` | string | Unique chunk identifier (e.g. `rome_i_art_6_1`) |
+| `instrument` | string | Short name of the legal instrument (e.g. `Rome I`) |
+| `jurisdiction` | string | Governing jurisdiction (always `EU` for this subset) |
+| `article` | string | Article reference (e.g. `Art. 6(1)`) |
+| `title` | string | Human-readable title of the provision |
+| `text` | string | Verbatim statutory text of the provision |
+| `url` | string | Permalink to the source EUR-Lex HTML page |
+| `topics` | list[str] | Thematic tags (e.g. `["consumer protection", "choice of law"]`) |
+| `date` | string | Date of the regulation (ISO 8601) |
+| `celex` | string | Official EUR-Lex CELEX identifier |

+
+## Intended Use
+
+- Educational legal research
+- Retrieval-Augmented Generation (RAG) experiments in the legal domain
+- Benchmarking embedding models on EU statutory text
+
+---
+
+## Limitations
+
+- **Partial coverage**: Only the specific sub-articles most relevant to cross-border PIL scenarios are included.
+- **EU focus**: Does not cover national laws, case law, or non-EU jurisdictions.
+- **Static snapshot**: Regulation amendments enacted after the scrape date are not reflected.
+- **Not legal advice**: This dataset must not be used as the sole basis for legal decisions.
