# Configuration Wizard & Generator - Complete Enhancement Summary

## 🎉 All Improvements Complete!

We've transformed the configuration wizard and generator into a professional, production-ready solution that produces comprehensive, self-documenting configurations.

---

## Summary of All Changes

### 1. ✅ Fixed Generator Matching Logic (4 bugs fixed)
- **Variable collision in object properties** - Was using wrong URI
- **Overly long IRI templates** - Reduced from 6 columns to 1
- **Columns mapped to wrong class** - FK columns now excluded
- **FK IDs in object mappings** - Now properly filtered out

### 2. ✅ Improved IRI Templates
- **Before:** `mortgage_loan:{LoanID}_mortgage_loan:{BorrowerID}...`
- **After:** `{base_iri}mortgage_loan/{LoanID}`
- Uses `{base_iri}` placeholder for runtime substitution
- Clean format with forward slashes
- Object templates use correct FK IDs

### 3. ✅ Cleaned Up Namespaces
- **Before:** 30+ namespaces (brick, csvw, dc, dcat, etc.)
- **After:** 3-6 essential namespaces only
- Filters out W3C standards and third-party schemas
- Keeps only domain-specific namespaces

### 4. ✅ Added Object Property Datatypes
- **Before:** Missing `datatype` and `required` in object properties
- **After:** Complete metadata including datatypes and required flags
- Matches manual configuration style 100%

### 5. ✅ Created Custom YAML Formatter
- Professional formatting with box-drawing headers
- Section comments (# Column mappings, # Linked objects, etc.)
- Clean indentation with blank lines
- Automatic transform functions (to_decimal, to_date, to_integer)
- Proper quoting for IRI templates

### 6. ✅ Wizard Automatic Generation
- **Before:** Two-step process (wizard → generate command)
- **After:** One-step complete generation
- Wizard automatically runs generator
- Merges all wizard settings (validation, logging, options)
- Produces complete, ready-to-use configuration

### 7. ✅ Added Template Sections (NEW!)
- Commented validation configuration template
- Commented ontology imports template  
- Advanced features examples (multi-valued, conditional, transforms, etc.)
- Complete processing options reference
- Usage examples for common commands
- Self-documenting and educational

## Output Quality Comparison

### Manual Configuration (mortgage_mapping.yaml)
```yaml
namespaces:
  ex: https://example.com/mortgage#
  xsd: http://www.w3.org/2001/XMLSchema#
  rdfs: http://www.w3.org/2000/01/rdf-schema#

defaults:
  base_iri: https://data.example.com/

sheets:
  - name: loans
    source: ../data/loans.csv
    
    # Main resource configuration
    row_resource:
      class: ex:MortgageLoan
      iri_template: "{base_iri}loan/{LoanID}"
    
    # Column mappings (data properties)
    columns:
      LoanID:
        as: ex:loanNumber
        datatype: xsd:string
        required: true
      
      Principal:
        as: ex:principalAmount
        datatype: xsd:decimal
        transform: to_decimal
        required: true
```

# ✓ Detects foreign key relationships
# ✓ Adds datatypes and transforms
# ✓ Includes validation settings
# ✓ Adds template sections for unused features
# ✓ Saves formatted, self-documenting file

# Step 2: Review the generated file
# Open my_mapping.yaml and verify mappings
