Integration includes:
* Copied source files to raw/uk/{employment,ip,tax}/
* Added rows to manifests/download_manifest.csv with SHA-256 hashes
* Updated logs/download_log.csv with ingestion timestamps
* Ingested documents into Chroma vector database (5 docs -> 28 vectors)
* Updated ROADMAP.md with UK completion statistics

|
||||
# if-legal-corpus
|
||||
|
||||
Self-hosted legal document corpus for contract analysis and freelancer rights research. Contains international legislation, case law, and industry standards indexed in ChromaDB for semantic search.
|
||||
|
||||
## Quick Start
|
||||
|
||||
### Setup
|
||||
|
||||
```bash
|
||||
# Clone repository (already done)
|
||||
cd /home/setup/if-legal-corpus
|
||||
|
||||
# Create virtual environment
|
||||
python3 -m venv .venv
|
||||
source .venv/bin/activate
|
||||
|
||||
# Install dependencies
|
||||
pip install -r requirements.txt
|
||||
```
|
||||
|
||||
### Running Downloads
|
||||
|
||||
To download and process documents from the inventory:
|
||||
|
||||
```bash
|
||||
# Download all documents from LEGAL_CORPUS_IMPORT_LIST.md
|
||||
python scripts/download_all.py
|
||||
|
||||
# This will:
|
||||
# 1. Read LEGAL_CORPUS_IMPORT_LIST.md
|
||||
# 2. Download each document to raw/ subdirectories
|
||||
# 3. Log downloads to logs/download_log.csv
|
||||
# 4. Record manifest entries in manifests/download_manifest.csv
|
||||
```
|
||||
|
||||
### Running Chroma Ingestion
|
||||
|
||||
To index downloaded documents into ChromaDB for semantic search:
|
||||
|
||||
```bash
|
||||
# Ingest documents into Chroma vector database
|
||||
python scripts/ingest_chromadb.py \
|
||||
--manifest manifests/download_manifest.csv \
|
||||
--db-dir indexes/chromadb
|
||||
|
||||
# This will:
|
||||
# 1. Read all documents with status=success from manifest
|
||||
# 2. Extract text (supports .md, .pdf, .html, .json, .xml)
|
||||
# 3. Chunk text (1500 chars per chunk, 200 char overlap)
|
||||
# 4. Generate embeddings (using Chroma's default embedding)
|
||||
# 5. Store vectors with metadata in indexes/chromadb/
|
||||
```
|
||||

## Important Notes
|
||||
|
||||
### Chroma Database Size
|
||||
The ChromaDB indexes are large and should not be committed to git:
|
||||
- Add `indexes/chromadb/` to `.gitignore`
|
||||
- Regenerate vectors locally using `scripts/ingest_chromadb.py`
|
||||
|
||||
### Virtual Environment
|
||||
The `.venv/` directory is excluded from git. Install dependencies locally after cloning.
|
||||
|
||||
### Document Formats Supported
|
||||
- Markdown (`.md`)
|
||||
- PDF (`.pdf`)
|
||||
- HTML (`.html`)
|
||||
- XML (`.xml`)
|
||||
- JSON (`.json`)
|
||||
- Plain text
|
||||
|
||||
### Chunking Strategy
|
||||
- Default chunk size: 1,500 characters
|
||||
- Overlap: 200 characters
|
||||
- Configurable in `scripts/ingest_chromadb.py` via `chunk_text()` function
|
||||
|
||||

## Unable to download — reasons and workarounds
|
||||
- Items without direct URLs (for example, some case law rows) will be marked `no_direct_link` in the manifest. Extend the downloader to use CourtListener or other APIs by citation to automate these where possible.
|
||||
- HTTP 403 Forbidden errors on several domain (ftc.gov, legifrance.gouv.fr, sagaftra.org) indicate bot detection or access restrictions. Consider implementing delay-based retry with user-agent rotation.
|
||||
- Connection timeouts on house.gov and fairwork.gov.au indicate network/firewall issues. These should be retried during off-peak hours or from alternative IP ranges.
