Extraction Service

General-purpose extraction infrastructure for research-grade structured data extraction with full traceability.

Core Principle

Every extraction must be fully documented and traceable.

When extracting structured data from documents, each field links to source documentation. Complete audit trails for:

• metatopic-v3 topic extraction
• Document metadata extraction
• Variable extraction with codebook documentation
• Any domain requiring provenance

Why This Matters

LLM extractions without provenance are unreliable. This service provides:

• Schema registry for extraction targets
• Source documentation linking
• Version tracking
• Audit trails
