ddex validator

The ddex validator analyzes DDEX-compliant metadata and transfer payloads to verify structural correctness and schema conformance. It accepts XML or JSON inputs and supports multiple schema versions used in the music data ecosystem. The tool identifies missing fields, incorrect data types, unsupported versions, and duplicated identifiers, providing precise error locations to speed fixes.
Conceptually, the tool parses the document, loads the relevant DDEX schema, and applies rule checks per field and per document. It can operate in strict schema-aware mode or with a configurable set of business rules for exceptions. Results include a structured error list, a pass/fail status, and a machine-readable report suitable for CI pipelines.
Who benefits: software engineers integrating music catalogs, QA teams validating feeds, and distributors submitting metadata to partners. Unique value: batch validation, exportable reports, and ready-to-consume output for automation. Core features include line/offset error reporting, schema version matching, cross-field validation, and support for both XML and JSON inputs.
Use cases include pre-ingest validation of metadata packets, nightly QA runs, and integration tests for distributor pipelines.
