RDFog

A point cloud visualizer for RDF data with distributed storage.

Quick Start

1. Clone and install:

   git clone https://github.com/yourusername/RDFog.git
   cd RDFog
   python -m venv .venv
   source .venv/bin/activate
   pip install -r requirements.txt

2. Start distributed RDF servers:

   sudo docker-compose up -d

3. Run the visualizer:

   python3 main.py

What It Does

• Starts two Fuseki RDF servers with sample data
• Queries data from both servers using federated SPARQL
• Visualizes the combined RDF graph as a point cloud

Endpoints

• Server 1: http://localhost:3030
• Server 2: http://localhost:3031

Troubleshooting

• No data? Check: sudo docker logs fuseki1
• Permission error? Make sure: chmod +x entrypoint.sh
• Restart fresh: sudo docker-compose down -v && sudo docker-compose up --build -d
