Re: Like any good software project...

Makoto,

there is no obligation to necessarily use the Web Packaging approach for EPUB4. The schema below reflects a discussion we had in Toronto, whereby

- PWP may stay as a "conceptual" term for a packaged version of WP (essentially looking at issues whether there are additional, e.g., manifest requirements if a WP gets packaged by whatever means)
- EPUB4 may use the PWP but essentially re-using the packaging format used by EPUB3 (or maybe a simplification thereof).

In other words, EPUB4 may not be dependent on the advancement of Web Packaging. Actually, the possibility of using the EPUB3 packaging format was always an option, regardless of the state of Web Packaging.

Sincerely

Ivan
