Practical guide to validating SPDX SBOMs, checking serialization support, and diagnosing common document errors.

SPDX Validator

If you need to validate an SPDX SBOM quickly, use the SBOM Validator. It supports SPDX JSON, XML, RDF/XML, Tag-Value, YAML, and JSON-LD and gives format-aware feedback when a file fails.

This page focuses on practical SPDX validation: which serializations are common, what fields usually break validation, and how to debug format mismatches.

Start Here

Use the validator when you want to check:

  • whether an SPDX file is valid
  • which SPDX serialization was detected
  • whether document-level fields are missing
  • whether the file is ready for customer, procurement, or compliance use

Common SPDX Validation Failures

Missing document fields

Common failures include missing:

  • spdxVersion
  • dataLicense
  • SPDXID
  • document name or namespace information

Serialization mismatch

SPDX files may arrive as:

  • JSON
  • XML
  • RDF/XML
  • Tag-Value
  • YAML
  • JSON-LD

Auto-detect usually works best unless you know the exact family you are checking.

Incomplete package or relationship data

Validation may pass the basic format check but still reveal missing package metadata or relationship gaps that reduce downstream usefulness.

  1. generate or collect the SPDX file
  2. validate it with the SBOM Validator
  3. fix hard failures first
  4. review warnings if the file will be used for customer or audit workflows
