What is the purpose of the Matterhorn Protocol?

The Matterhorn Protocol is specifically designed to act as a conformance testing model for PDF/UA (PDF Universal Accessibility). This protocol establishes standardized methods for assessing whether PDF documents meet the accessibility requirements set forth in the PDF/UA specification. By providing a clear framework for testing, the Matterhorn Protocol ensures that documents are not only technically compliant but also usable by individuals with disabilities who rely on assistive technologies.

This focus on conformance testing is critical for ensuring that all PDF documents can be reliably accessed and navigated by users with varying abilities, helping to promote inclusivity and accessibility in digital content. The structured testing processes outlined in the Matterhorn Protocol yield consistent and actionable feedback, further assisting developers and content creators in producing accessible documents.
