The 5 EPUB Accessibility Metadata Fields Most Publishers Forget

 


An EPUB can be technically functional and still leave important accessibility information undefined.

That is where EPUB accessibility metadata becomes important.

Accessibility metadata helps publishers communicate the accessibility characteristics of a digital publication and allows platforms, libraries, retailers, and readers to understand what accessibility features are available.

Here are five metadata areas publishers should pay attention to.

1. accessMode

This identifies the access modes required to consume the content, such as textual or visual access.

2. accessibilityFeature

This describes accessibility features available within the publication, such as alternative text, structural navigation, captions, or MathML.

3. accessibilityHazard

This identifies potential accessibility hazards, such as flashing content or motion simulation.

4. accessibilitySummary

This provides a human-readable summary of the publication’s accessibility characteristics.

5. accessModeSufficient

This helps indicate which access modes are sufficient for consuming the publication.

These fields are particularly important for publishers producing accessible EPUB3, academic ebooks, scholarly publications, and digital learning content.

But adding metadata is not enough. The metadata needs to accurately represent what the EPUB actually contains. If an EPUB claims to provide accessible navigation or alternative text, those features need to exist and work correctly.

This is why EPUB accessibility testing and validation should be part of the production workflow rather than a last-minute metadata exercise.

For publishers working toward WCAG compliance and EPUB accessibility, getting the underlying content right is just as important as declaring its accessibility characteristics.

LaTeX, InDesign, or Proprietary Engines: The Great Debate for STM Publishers

  Scientific, Technical, and Medical (STM) publishers face a critical decision when it comes to production workflows: which tool best balances precision, efficiency, and scalability? Among the most discussed options are LaTeX , Adobe InDesign , and proprietary publishing engines . Each brings unique strengths along with trade-offs that can influence publishing quality and timelines. LaTeX: The Gold Standard for Precision For complex equations, structured content, and highly technical manuscripts, LaTeX remains unmatched . Its markup-based system ensures that even the most intricate mathematical formulas render flawlessly. It is also well suited for journals requiring consistent style and reference management. However, LaTeX can feel intimidating to authors unfamiliar with coding syntax, and collaboration often requires extra tools to make it accessible to non-technical contributors. InDesign: Design Flexibility at Its Core Adobe InDesign offers unparalleled creative freedom . ...

Why Quality Typesetting Still Shapes the Reader’s Experience

Image
  A reader often notices the story first, but it is the typesetting that shapes how comfortably that story is absorbed. Good typesetting is quiet; it does its work without calling attention to itself. Yet it silently improves readability, flow, and comprehension in ways that define the entire reading experience. Press enter or click to view image in full size Typesetting controls the rhythm of how text is seen on the page. Line spacing, hyphenation, paragraph structure, and font selection all contribute to how naturally the eye moves. Even a small inconsistency can interrupt focus, while thoughtful typesetting makes reading feel effortless. For publishers, this is not just about aesthetics. It is about quality, clarity, and credibility.   Digital publishing adds another layer. Content must adapt to screens of various sizes without losing structure. Clean styling, responsive typography, and consistent hierarchy determine whether a digital page feels organized or overwhelming. W...
