Advanced Hybrid Layouts Working Group
The Advanced/Hybrid Layouts working group intends to publish a set of modular specifications that extends EPUB3 functionality to better meet the full needs of the ecosystem with regards to user and context adaptation and reading of image-based publications such as comics and magazines.
The Advanced/Hybrid Layouts working group is operating under a charter granted by the IDPF membership.
The AHL specifications are currently Proposed Specifications. Membership review is ongoing.
The next, and final, projected milestone is publication of Recommended Specifications in the Fall of 2015.
Adoption Readiness Roadmap
Adoption readiness roadmaps are now available for the following specifications:
- EPUB Multiple Renditions The purpose of this document is to describe how create and use EPUB documents with multiple renditions. This will cover handling publication wide metadata, rendition selection (from multiple renditions in an EPUB container), and navigation between renditions.
- EPUB Region-Based Navigation The purpose of this document is to describe how guided navigation through one rendition can be implemented using embedded Regions of Interest in the Navigation document. Navigation documents are already defined in EPUB3 content documents and we are extending them for intra-documentation navigation.
- Magazine Structural Vocabulary
- Previews in EPUB (use case)
