Coordinator's summary of submitted EGLS requirements

1. Overview of EGLS requirement list MURATA Makoto JEPA and International University of Japan 1 EPUB WG/EGLS Sub-group 2010/8/3

2. Status Similar requirements submitted by different members, but they have not been unified yet. Hebrew, Arabic, Mongolian and Korean requirements? Will be reviewed by the entire WG Requirements are not guaranteed to be satisfied, while non-requirements are unlikely to be considered. Will be frozen in October(?) after publishing the first Public Working Draft 2 EPUB WG/EGLS Sub-group 2010/8/3

7. Writing mode EGLS_MM_01 Vertical Writing EGLS_TK_05 Vertical text layout EGLS_Voyager_01 Horizontal and Vertical writing/Binding Direction EGLS_TW_1: Let EPUB 2.1 OPS support CSS3 subset --> Text Layout Module EPUB WG/EGLS Sub-group 7 2010/8/3

8. EPUB WG/EGLS Sub-group 8 2010/8/3

9. EGLS_MM_02 Principal Text Direction (or principal writing mode) Typically, one per book. Quite a few exceptions, however. EPUB WG/EGLS Sub-group 9 2010/8/3

10. EGLS_MM_03 Column progression and Page progression EPUB WG/EGLS Sub-group 10 2010/8/3

11. EGLS_MM_04 Writing mode of captions and table entries EPUB WG/EGLS Sub-group 11 2010/8/3

12. EGLS_MM_05 Switching principal text directions Fallback to horizontal writing should be possible for users of vertical-writing-unaware reading systems. Users should be allowed to choose their favorite principal text direction. EPUB WG/EGLS Sub-group 12 2010/8/3

13. EGLS_MM_06 Stylesheets for more than one principal text direction The design of CSS2 hinders this requirement. Typically, vertical writing HTML documents (such as this example HTML document) for one principal text direction only. Note: Really good layout can be achieved only when both contents and stylesheets are dedicated to one particular principal text direction. However, switching should not lead to unreasonable layouts.

29. EGLS_TW_6: Complete Continuity of Content has Highest Priority Small size screen (or low resolution) reading device may not display whole ruby markup correctly. Readers may not need the ruby, but concern the continuity of content. Students could choose to have RUBY displayed while learning ZhuyinFuhao.
