## Integration Notes

### OCR Integration (Optional Future Enhancement)

If OCR detection is needed for this field:

1. Update `assets/js/ocr-field-mapper.js`:
   ```javascript
   'nature_of_solemnization': 'nature_of_solemnization'
   ```

2. OCR should detect keywords:
   - "Church", "Parish", "Cathedral" → Map to "Church"
   - "Civil", "Judge", "Mayor", "City Hall" → Map to "Civil"
   - "Mosque", "Temple", "Imam", "Rabbi" → Map to "Other Religious Sect"

## Support

For any issues or questions regarding these changes, please refer to:
- PHP error log: `logs/php_errors.log`
- Browser console for JavaScript errors
- Database query logs in MySQL

## Database Verification

**Command to verify column:**
```bash
cd c:/xampp/mysql/bin
./mysql.exe -u root -e "DESCRIBE iscan_db.certificate_of_marriage;" | grep nature
```

**Expected Output:**
```
nature_of_solemnization    enum('Church','Civil','Other Religious Sect')    YES        NULL
```
