A relevant improvement for accessibility: DPUB-ARIA and DPUB-Accessibility API Mappings 1.1
Research and development
The World Wide Web Consortium (W3C) has officially published the Digital Publishing WAI-ARIA Module 1.1 (DPUB-ARIA 1.1) and the Digital Publishing Accessibility API Mappings 1.1 (DPUB-AAM 1.1) as web standards (W3C Recommendations).
It represents a critical improvement for the accessibility of digital content and publications, as it allows to significantly enhance the experience of users with disabilities and those who rely on assistive technologies.
The critical role of DPUB-ARIA in accessible digital publishing
While web semantics provide a rich foundation for content structure, they fall short of capturing the nuanced semantic relationships found in traditional publishing. Publications rely heavily on visual conventions to convey meaning: subtle typographic cues that distinguish subtitles from main headings, visual indicators that mark footnote references, or distinctive formatting that signals a book’s dedication page or Table of Contents. For readers who are blind or have low vision, these graphic conventions remain invisible, creating a significant gap in the reading experience.
DPUB-ARIA roles bridge this divide by providing a standardized way to embed the same semantically rich information that sighted readers derive from visual design directly into the markup. This ensures that users of assistive technologies can access the full structural and contextual richness of digital publications, experiencing the same level of navigational clarity and semantic understanding that visual design traditionally provides.
Assistive Technology adoption and industry progress
The adoption of DPUB-ARIA roles by assistive technologies has been gradual over the years, requiring sustained advocacy and collaboration across the accessibility community. Since 2019, Fondazione LIA has spearheaded efforts within the DAISY Consortium to systematically map the implementation of DPUB-ARIA roles across different screen readers and to advocate with developers for broader support of these semantic markers.
This persistent outreach and technical collaboration have yielded significant results: many assistive technologies now support the core DPUB-ARIA roles, with TalkBack on Android currently leading the field by announcing all semantic roles defined in the specification to users. This progress represents a crucial milestone in making digital publications truly accessible end-to-end: from publishers to end users.
About digital publishing ARIA standards
The DPUB-ARIA module defines a set of specialized ARIA (Accessible Rich Internet Applications) roles that help users of assistive technologies navigate and understand the structural elements of digital publications. These roles are particularly relevant for long-form content, such as ebooks.
The specification DPUB-AAM defines how user agents (such as ebook readers) map the DPUB-ARIA markup to platform accessibility APIs. This ensures that assistive technologies can interpret and present this structural information accurately to users with disabilities. It is intended for developers who are responsible for accessibility in their user agent so that they can support the accessibility content produced for digital publishing.

Updates since version 1.0
Version 1.1 introduces several important updates from the previous ones, including:
- The addition of two new roles: doc-page-header and doc-page-footer, which allow for better identification and navigation of recurring header and footer elements within paginated content.
- mappings updates to accessibility application programming interfaces (APIs) to improve cross-platform consistency and support.
The adoption of these standards is expected to improve the reading experience for people with disabilities and foster greater accessibility in the growing ecosystem of digital books and documents.
