Legalaxy

Legal concept knowledge graph — hierarchical WordNet for law. Data lives in Google Sheets, frontend on GitHub Pages, no server.

Setup

1. Google Sheet

Open the sheet and create three tabs named exactly: Nodes, Edges, Log

Paste these headers into row 1 of each tab:

Nodes:

id	label	layer	parent_id	definition	citation	authority_level	jurisdiction	temporal_valid_from	temporal_valid_to	notes

Edges:

id	from_id	to_id	relationship_type	citation	jurisdiction	strength	temporal_valid_from	temporal_valid_to	notes

Log:

timestamp	action	node_or_edge	id	user_note

2. Apps Script

1. In the Sheet, go to Extensions > Apps Script
2. Delete any existing code and paste the contents of Code.gs
3. Click Deploy > New deployment
4. Type: Web app
5. Execute as: Me
6. Who has access: Anyone
7. Click Deploy, authorize when prompted, copy the deployment URL

3. Frontend

In index.html, replace line:

const APPS_SCRIPT_URL = 'YOUR_APPS_SCRIPT_URL';

with your deployment URL.

Commit index.html to the root of the nicholasdhaliwal/legalaxy GitHub repo. GitHub Pages will serve it at nicholasdhaliwal.github.io/legalaxy.

4. Seed data

Install node-fetch if needed:

npm install node-fetch

Run the seed script:

node seed.js YOUR_APPS_SCRIPT_URL

This populates 60 nodes (1 root, 7 domain, 52 subdomain) and their edges. Takes about 2-3 minutes due to Apps Script rate limits.

5. Visit the app
