# Metadata Extraction

## Workflow
1. Identify supported artifact types and target metadata fields.
2. Extract metadata with deterministic tools and preserve original artifacts.
3. Normalize timestamps, encodings, and identifiers to a common schema.
4. Validate quality (missing fields, malformed values, duplicates).
5. Store enriched outputs with provenance and extraction method details.
