**Questions:**
- Data file path
- Format (auto-detected from extension)
- Show column preview?

**Smart Features:**
- Auto-detects format (CSV, Excel, JSON, XML)
- Analyzes data structure
- Shows column types and sample values
- Counts rows and null values

**Supported Formats:**
- `.csv` - CSV files
- `.tsv` - Tab-separated files
- `.xlsx` - Excel workbooks
- `.json` - JSON documents
- `.xml` - XML documents

### Step 2: Ontology

**What it does:** Configures your target ontology

**Questions:**
- Do you have an ontology file?
- Ontology file path
- Does it import other ontologies?
- Import file paths (optional)

**Smart Features:**
- Validates ontology file exists
- Supports multiple imports
- Can suggest templates for new ontologies

### Step 3: Target Class

**What it does:** Defines the main entity in your data

**Questions:**
- Target class URI (the main concept)
- IRI template (how to generate identifiers)

**Smart Features:**
- Suggests ID columns from your data
- Shows example IRI template
- Validates URI format

**Example Templates:**
```
Simple:        http://example.com/Person/{id}
With prefix:   http://myorg.com/employees/{employee_id}
Composite:     http://example.com/Loan/{year}/{loan_number}
```

### Step 4: Processing Options

**What it does:** Optimizes for your use case

**Questions:**
- Processing priority (1-4)

**Priority Options:**

#### 1. Speed Priority
- **Use case:** Quick results, small to medium files
- **Settings:** Disables semantic matching, no streaming
- **Best for:** Development, testing, files < 100K rows
- **Speed:** Fastest (2-5x faster)
- **Quality:** Good (70-80% success rate)

#### 2. Memory Priority
- **Use case:** Large files that don't fit in memory
- **Settings:** Enables streaming, chunk processing
- **Best for:** Files > 1M rows, limited RAM
- **Speed:** Moderate
- **Quality:** Good (75-85% success rate)
- **Memory:** Constant (handles any file size)

#### 3. Quality Priority
- **Use case:** Best possible matching
- **Settings:** All matchers enabled, continuous learning
- **Best for:** Production mappings, complex data
- **Speed:** Slower (but thorough)
- **Quality:** Excellent (90-95% success rate)

#### 4. Balanced (Recommended)
- **Use case:** Most common scenarios
- **Settings:** Semantic matching ON, streaming OFF
- **Best for:** Most use cases
- **Speed:** Good
- **Quality:** Very Good (85-95% success rate)

### Step 5: Output Format

**What it does:** Configures RDF output

**Questions:**
- Output RDF format
- Output file path
- Enable SHACL validation? (optional)

**Format Options:**
- `turtle` - Turtle format (recommended, human-readable)
- `nt` - N-Triples (simple, line-oriented)
- `jsonld` - JSON-LD (for web APIs)
- `rdfxml` - RDF/XML (for legacy systems)

### Step 6: Advanced Options (Optional)

**What it does:** Fine-tunes matching behavior

**Questions:**
- Customize matching thresholds?
  - Semantic matching threshold (0.0-1.0)
  - Fuzzy matching threshold (0.0-1.0)
- Enable semantic matching?
- Enable graph reasoning?
- Enable mapping history?
- Enable detailed logging?

**When to use:**
- You understand confidence thresholds
- You need specific feature combinations
- You want detailed logs for debugging

## Tips & Best Practices

### For Beginners

1. **Start with Balanced Priority**
   - Good balance of speed and quality
   - Works for most use cases

2. **Use Data Preview**
   - Understand your data structure
   - Identify ID columns
   - Check for null values

3. **Accept Smart Defaults**
   - Wizard suggests good values
   - Can refine later if needed

### For Advanced Users

1. **Quality Priority for Production**
   - Enable all matchers
   - Use graph reasoning
   - Enable learning system

2. **Memory Priority for Big Data**
   - Files > 1M rows
   - Limited RAM available
   - Need constant memory usage

3. **Customize Thresholds**
   - Lower for more matches (but less confident)
   - Higher for fewer, high-quality matches

### For Performance

1. **Speed Priority**
   - Development/testing
   - Iterating on configuration
   - Small to medium files

2. **Disable Expensive Features**
   - Turn off semantic matching
   - Disable graph reasoning
   - Use exact/fuzzy only

## Integration with Workflow

### Complete Workflow

```bash
# 1. Create configuration
rdfmap init --output config.yaml

# 2. Generate mapping
rdfmap generate \
  --config config.yaml \
  --alignment-report alignment.json

# 3. Review alignment report
cat alignment.json

# 4. Convert data
rdfmap convert \
  --mapping config.yaml \
  --validate

# 5. Check validation report
cat validation_report.json
```

### Iterative Refinement

```bash
# Try quick version first
rdfmap init  # Choose Speed priority
rdfmap generate --config mapping_config.yaml

# Review results, then go for quality
rdfmap init  # Choose Quality priority
rdfmap generate --config mapping_config_v2.yaml
```

## Troubleshooting

### "File not found" Error

**Problem:** Wizard can't find your data or ontology file

**Solution:**
- Use absolute paths: `/full/path/to/file.csv`
- Or relative to current directory: `./data/file.csv`
- Check file spelling and extension

### Data Analysis Fails

**Problem:** Wizard can't analyze your data file

**Solution:**
- Check file format is supported
- Ensure file isn't corrupted
- For Excel: file must be `.xlsx` (not `.xls`)
- For JSON: must be valid JSON format

### "Configuration cancelled" Message

**Problem:** You pressed Ctrl+C during setup

**Solution:**
- Restart wizard: `rdfmap init`
- Answer all questions to completion
- Or press Ctrl+C to intentionally cancel

### Estimates Seem Wrong

**Problem:** Match rate or time estimates don't match actual results

**Solution:**
- Estimates are approximate
- Based on configuration and data preview
- Actual results depend on:
  - Data complexity
  - Ontology structure
  - System performance

## Comparison: Manual vs Wizard

### Manual Configuration (Before)

```yaml
# You had to know all these settings and write them manually
data_source: data.csv
format: csv
ontology: onto.ttl
target_class: http://example.com/Thing
iri_template: http://example.com/Thing/{id}
use_semantic: true
semantic_threshold: 0.6
use_graph_reasoning: true
graph_reasoning_threshold: 0.6
use_history: true
use_structural: true
structural_threshold: 0.5
use_datatype: true
datatype_threshold: 0.7
streaming: false
output_format: turtle
output: output.ttl
enable_logging: true
log_file: mapping.log
```

# Use the generated config
print(f"Generated config with {len(config)} settings")
print(f"Data source: {config['data_source']}")
print(f"Priority: {config['priority']}")
```

### With Custom Logic

```python
from rdfmap.cli.wizard import ConfigurationWizard

wizard = ConfigurationWizard()

# Configure each step programmatically
wizard.config['data_source'] = 'data.csv'
wizard.config['format'] = 'csv'
