Accessibility workflow

This workflow is designed to validate PDF documents for compliance with accessibility standards, including PDF/UA (ISO 14289), Web Content Accessibility Guidelines 2.1 (WCAG), and general quality guidelines. The output includes a structured report containing accessibility issues categorized by severity and standard.

This workflow supports the following features:

  • PDF/UA validation (ISO 14289-1).
  • WCAG 2.1 validation (PDF-specific interpretations).
  • General quality checks.
  • Customizable filtering of issue severities (for example, ignore or deny warnings).
  • JSON and XML report outputs.
  • Warning mappings with extensibility based on the PAC tool.
  • Compatible with Docker and Windows deployments.

Supported input file formats​

This workflow supports any input in PDF format:

  • PDF 1.x, PDF 2.0
  • PDF/A-1, PDF/A-2, PDF/A-3
  • PDF with tags, annotations, or layers.

Output structure​

The result is structured as a hierarchy of issue nodes, each of which may contain:

  • Severity: Warning, Failure, Termination
  • Standard: PDF/UA, WCAG, Quality
  • Category and Subcategory (for example Basic Requirements → Natural Language)
  • The bounding box (for visual issues)
  • Page index
  • Message

Output formats​

  • JSON
  • XML

Document options​

Document options apply only to a specific input. It allows you to determine specific properties based on an individual document rather than as a global setting (either determined by the job or the profile). Any subsequent jobs processed with the workflow profile use the profile's default settings.
