## 🚀 Quick Start

### Use It (No Changes Required)
```bash
rdfmap generate \
  --ontology ontology.ttl \
  --data data.csv \
  --output mapping.yaml
```

Everything is enabled by default: semantic matching, type validation, AND learning from history!

### Custom Pipeline
```python
from rdfmap.generator.matchers import create_custom_pipeline
from rdfmap.generator.matchers.exact_matchers import ExactPrefLabelMatcher
from rdfmap.generator.matchers.semantic_matcher import SemanticSimilarityMatcher
from rdfmap.generator.matchers.datatype_matcher import DataTypeInferenceMatcher
from rdfmap.generator.matchers.history_matcher import HistoryAwareMatcher

pipeline = create_custom_pipeline([
    ExactPrefLabelMatcher(),
    HistoryAwareMatcher(threshold=0.65),  # NEW!
    SemanticSimilarityMatcher(threshold=0.7),
    DataTypeInferenceMatcher(threshold=0.75)
])

generator = MappingGenerator(..., matcher_pipeline=pipeline)
```

## 📚 Documentation

- `docs/PHASE_1_COMPLETE.md` - Semantic matching
- `docs/PHASE_2_COMPLETE.md` - Matcher architecture
- `docs/PHASE_3_COMPLETE.md` - Complete Phase 3 summary ← NEW!
- `docs/DATATYPE_MATCHER.md` - Type inference guide
- `docs/COMPREHENSIVE_ANALYSIS_AND_ROADMAP.md` - Full plan

## 🎓 Key Concepts

### Semantic Matching (Phase 1)
- Uses BERT embeddings
- Understands `customer_id` ≈ `clientIdentifier`
- Expands acronyms: `ssn` → `socialSecurityNumber`
- Threshold: 0.6 (adjustable)

### Matcher Pipeline (Phase 2)
- Plugin architecture
- 10 built-in matchers
- Composable and extensible
- Easy to test

### Data Type Inference (Phase 3a)
- Validates type compatibility
- Prevents wrong mappings (integer ≠ string)
- Reads OWL datatype restrictions
- Boosts confidence when types align

### Mapping History (Phase 3b) ← NEW!
- Stores all mapping decisions in SQLite
- Learns from past successes
- Boosts confidence for proven patterns
- Gets smarter with every use!

## 🔧 Troubleshooting

### Slow first run?
The semantic model downloads ~80MB on first use (10-15 seconds).

### Want to disable features?
```python
# Disable semantic matching
pipeline = create_fast_pipeline()

# Disable data type matching
pipeline = create_default_pipeline(use_datatype=False)

# Disable history learning ← NEW!
pipeline = create_default_pipeline(use_history=False)

# Only exact matches
pipeline = create_exact_only_pipeline()
```

### Where is the history database? ← NEW!
```
~/.rdfmap/mapping_history.db
```

You can export it, share it, or delete it:
```python
from rdfmap.generator.mapping_history import MappingHistory

history = MappingHistory()
history.export_to_json("backup.json")  # Backup
history.clear_history()  # Reset (careful!)
```
