  • EPUB: The Good
    • Fills critical role in the ecosystem as the publication-level interchange and delivery format standard
    • Based on Web Standards ( “shrink-wrapped” XHTML)

    • HelloWorld.epub= 4 files zipped in a Byzantine manner)
    • Under-specified content & Reading System conformance requirements
    • Test suites lacking and lagging
    • Incomplete support by authoring tools and Reading Systems
    • Browser-based Reading Systems were not top of mind
    • Missing important features
    • Interactivity, video, audio, annotations, cross-document linking, vertical writing, audio sync, dictionaries, complex page layouts, mathematics
