3Xmap Studio is a visual editor for R2RML and RML mappings. It is built with Streamlit and uses Morph-KGC to create the knowledge graph.

• Supports relational databases and CSV files (more formats to come).
• Guide mapping development through pre-loaded ontologies.
• Create RML views over relational databases with SQL.
• Export the RML mapping and create the knowledge graph.
• Explore your mapping.
• Save the session for later.

You can run 3Xmap Studio by cloning this repository and executing:

pip install -r requirements.txt
python -m streamlit run 0_3xmap-studio.py

We recommend to use virtual environments to install 3Xmap Studio.
