JSON schemas for validating according to the the ADIwg project and data metadata standard. The schemas comply with JSON Schema draft version 4.

The mdtranslator was written by the Alaska Data Integration Working Group (ADIwg) to assist with creating ISO 19139 metadata records. Input to the mdtranslator is JSON conforming to the mdJson-schema. The mdtranslator architecture allows developers to write additional readers for other input formats and/or write additional writers for other output other than ISO 19139.
