## Summary
This submission demonstrates semantic augmentation of the FDIC Summary of Deposits (SOD) dataset using:
- An RDF/OWL ontology aligned with FIBO and GeoNames
- SHACL validation rules for business quality checks
- A Streamlit-based transformation and validation app
- A recorded video walkthrough explaining the solution and demo

## Key Files
- `fdic_ontology_fixed.ttl`: Core ontology
- `fdic_shacl_constraints_optimized.ttl`: Data validation logic
- `fdic_transformer_app2.py`: CSV to RDF transformer with SHACL validator
- `video1218473765.mp4`: End-to-end explanation and demonstration

## Instructions
1. Run the Streamlit app using:
   ```bash
   streamlit run fdic_transformer_app2.py
   ```
2. Upload the FDIC CSV file when prompted
3. Transform to RDF and validate with SHACL
4. Download the outputs for further integration
