# Code of Virginia

## Dataset Summary

This dataset contains **32,615 fully structured sections of the Code of Virginia**, organized into titles, chapters, and individual statute sections.  
Each entry contains the official section number, a short descriptive heading, **the full statute text in HTML**, and metadata linking to the canonical public URL.

This dataset is designed for:

- Legal text retrieval  
- RAG (Retrieval-Augmented Generation) applications  
- Classification, summarization, and legal NLP research  
- Building structured indexes and embeddings of statutory law

---

## Dataset Description

### Contents

Each row represents **one statute section**, including:

- Full section text (with HTML `<p>` tags, internal links, sidenotes)
- Hierarchical metadata: title → chapter → section
- Canonical source URLs from the **Virginia Legislative Information System**
- Consistent jurisdiction and identifier metadata

### Why this dataset?

The Code of Virginia is complex and deeply nested.  
This dataset normalizes all hierarchy levels and provides a machine-friendly JSONL dataset ideal for:

- Retrieval engines  
- Embedding pipelines  
- Legal QA systems  
- Agentic legal tools  
- Law-aware LLM finetuning  

### Languages

- English (legal statutory domain)

## Dataset Structure

### Example Instance

```json
{
  "section_id": "VA:1-1",
  "section_number": "1-1",
  "section_name": "Contents and designation of Code",
  "section_text": "<p>The laws embraced in this and the following titles, chapters, articles and sections of this act shall constitute, and be designated and cited as the \"Code of Virginia,\" hereinafter referred to as \"the Code\" or \"this Code.\"</p><p>Code 1919, § 1; R. P. 1948, § 1-1. </p><p class='sidenote'>The chapters of the acts of assembly referenced in the historical citation at the end of this section may not constitute a comprehensive list of such chapters and may exclude chapters whose provisions have expired.</p>",
  "section_source_url": "https://law.lis.virginia.gov/vacode/title1/chapter1/section1-1/",
  "chapter_id": "VA:Title-1-Chapter-1",

}
```

## Data Creation & Processing

### Source & Collection

All statutory text was collected from the **Virginia Legislative Information System (LIS)**, which publishes the official Code of Virginia.  
Collection used publicly available endpoints documented at:

**API Documentation:** https://law.lis.virginia.gov/developers/  
**Public Website:** https://law.lis.virginia.gov/

### Fetch Date

All data was fetched and processed in **October 2025**.  
This represents a snapshot of the Code of Virginia as it existed on that date.

### Processing Steps

1. **Programmatic extraction** of all Titles → Chapters → Sections using the LIS API and HTML pages.  
2. **Normalization of identifiers**, including:
   - `section_id` (internal unique key)
   - `title_id`, `chapter_id`
   - cleaned numeric fields (`section_number`, etc.)
3. **Preservation of HTML** inside `section_text`, including:
   - `<p>` tags  
   - sidenotes  
   - cross-reference hyperlinks  
   - historical citations  
4. **Canonical URL mapping**: each section includes its LIS URL for reference.  


### Licensing & Data Rights

The Code of Virginia is **public domain**, and the statutory text is publicly accessible.  
No copyrighted commentary, annotations, or proprietary publisher material is included.  
No personal information, case records, or PII appear in this dataset.

## Considerations for Use

### Limitations

- The dataset is a **snapshot of October 2025**; statutes may have changed since then.
- `section_text` is stored in **HTML format**.  
  Users may need to strip or parse tags for plain-text NLP tasks.
- Historical notes, repealed markings, and cross-references are included and may require preprocessing depending on use case.
- Some sections include internal hyperlinks to other LIS pages which may shift as the LIS site updates.

### Ethical & Responsible AI Considerations

- Models trained on statutes **cannot substitute for legal advice**.  
- Outputs may be incomplete, outdated, or misinterpreted by the model.  
- Any application built on this dataset should:
  - Provide disclaimers  
  - Include human review  
  - Avoid suggesting authoritative interpretations of law  

### Jurisdictional Scope

All text applies to the **Commonwealth of Virginia** only.  
Do not assume applicability to other jurisdictions without verification.

## How to Use

### Load the Dataset

```python
from datasets import load_dataset

ds = load_dataset("dcrodriguez/Code-of-Virginia") 
train = ds["train"]

train[0]
```
