# Review: MIGRAT → main library migration verification

**Date:** 2025-01 (historical verification)  
**Artifact type:** Migration verification  
**Scope:** MIGRAT folder vs main library (`src/exonware/xwschema/`)  
**Outcome:** ✅ Complete — all MIGRAT features verified in main library; MIGRAT can be removed.

---

## Summary

All features from the MIGRAT version have been verified as implemented in the main library. The main library uses XW naming (e.g. `XWSchema`, `XWSchemaValidator`), engine-driven orchestration, dedicated validator/generator/builder, format registry, and comprehensive error system. Main library also adds OpenAPI, GraphQL, Avro, Protobuf, Swagger, WSDL support; schema generation from data; async operations.
