Webtoons spec for EPUB
No appropriate features even in EPUB 3.3
- Apple use "rendition:flow" but it's not correct use
- KADOKAWA use original metadata but it's not official
No conclusions in TPAC 2022
We just decided to add note for possible use of "rendition:flow"
Webtoons spec for EPUB
Ambiguous in EPUB Reading Systems 3.3
Situation in Japan
Already adopted by some Reading Systems
"rendition:flow" is required for EPUB-based Webtoons
- Apple: Ready for sideloaded EPUB
- Amazon: Guideline for Fliptoon
- ACCESS: Used at many ebook stores in Japan
"rendition:flow" in OPF
Both "pre-paginated" and "rendition:flow" are specified
Demo
With "rendition:flow"
Without "rendition:flow"
Proposal
- Permit to use "rendition:flow-scrolled-continuous" in FXL for Webtoons and update EPUB spec as a class-3 change.
Opinion
Introducing new metadata or property will not be welcome to the market and Apple and Amazon may not follow it.
