Last Call for Review of Proposed Corrections to EPUB 3.3

 The Publishing Maintenance Working Group has proposed corrections to the W3C Recommendation of EPUB 3.3. EPUB® 3 defines a distribution and interchange format for digital publications and documents. The EPUB format provides a means of representing, packaging, and encoding structured and semantically enhanced web content — including HTML, CSS, SVG, and other resources — for distribution in a single-file container. This specification defines the authoring requirements for EPUB publications and represents the third major revision of the standard.

Proposed corrections are marked in the document. Comments, including implementation experience, are welcome via GitHub through 10 March 2025.

Image
With nearly 94% of marketers now using AI in their content workflows, 2026 has officially made AI-powered SEO the new standard. Traditional keyword stuffing and manual research are outdated. The game has shifted to Generative Engine Optimization (GEO) — getting your content cited in AI Overviews, ChatGPT answers, Perplexity, Gemini, and beyond.

Open Task Forces to Discuss Web Schemas, Data Formats

The W3C's Semantic Web Interest Group has recently launched two new task forces to foster open collaboration and innovation in the world of web schemas and structured data. This move marks a significant step forward in enhancing how structured information is represented, shared, and understood across the web. A Shared Language for the Web At the center of this initiative is the growing adoption of schema.org , which provides a rich collection of schemas that webmasters can use to markup their pages in ways recognized by major search providers like Google, Bing, Yahoo, and Yandex.
