EPUB 3 introduces several key improvements in metadata processing over EPUB 2. Some of the notable improvements include:
1. Enhanced Semantic Markup: EPUB 3 allows for richer semantic markup through the use of HTML5 and other technologies, enabling better structuring and labeling of content, which in turn enhances the metadata processing capabilities.
2. Richer Metadata Support: EPUB 3 provides support for a wider range of metadata properties, including those defined in the Dublin Core Metadata Initiative (DCMI) and other metadata schemas, allowing for more comprehensive and detailed descriptions of publications.
3. Accessibility Metadata: EPUB 3 includes improved support for accessibility metadata, making it easier to provide essential information about accessibility features and requirements for readers with disabilities.
4. Global Language Support: EPUB 3 offers enhanced support for multilingual publications, allowing for more robust representation of metadata in various languages and scripts.
5. Media Overlays Metadata: EPUB 3 introduces support for media overlays, enabling synchronization of audio and text elements, and includes specific metadata for defining and managing these overlays.
6. Linking and Navigation Improvements: EPUB 3 includes enhancements to linking and navigation within publications, providing better ways to express relationships between different parts of the content, which can be reflected in the metadata.
Overall, EPUB 3's improvements in metadata processing contribute to a more flexible, versatile, and standardized approach to describing and organizing publication metadata, offering benefits for both content creators and end users.
