Running

Quick Start

1. Setup Environment variables

Important: Change default passwords in .env for security.

# Copy the environment template
cp env.template .env

# Edit .env with your configuration (make sure to change passwords!)
nano .env  # or use your preferred editor

2. Start Services

Recommended: Use the wrapper script (includes Ollama setup + pgAdmin config):

chmod +x start_services.sh
./start_services.sh

3. Access Services

Once started, services are accessible at:

• API Token Manager (Django): http://localhost:8000/
  • Once you register JWT user you need to activate it using token manager. You can also assign permission.
• Query Service (FastAPI): http://localhost:8010/
  • Now supports ingestion than just querying.
• ML Service (FastAPI): http://localhost:8007/
  • Integrates StructSense
• Oxigraph SPARQL: http://localhost:7878/ (password protected) graph database
• pgAdmin: http://localhost:5051/
