Daniel Glazman believes that EPUB has reached a technical dead end.

  • It is impossible to aggregate a set of web pages into a EPUB book through a trivial zip, and it is impossible to unzip an EPUB book and make it readable inside a Web browser even with graceful degradation.
  • Despite the International Digital Publishing Forum merging with W3C in January 2017, EPUB continues to diverge from web standards.
  • The EPUB 3.1 specification has been rescinded because it is too costly and complex for the eBook industry to adopt.

Mr. Glazman's solution? The WebBook format. From the announcement:

I have then decided to work on a different format for electronic books, called WebBook. A format strictly based on Web technologies and when I say "Web technologies", I mean the most basic ones: html, CSS, JavaScript, SVG and friends; the class of specifications all Web authors use and master on a daily basis. Not all details are decided or even ironed, the proposal is still a work in progress at this point, but I know where I want to go to.

[...] I have started from a list of requirements, something that was never done that way in the EPUB world:

  1. one URL is enough to retrieve a remote WebBook instance, there is no need to download every resource composing that instance
  2. the contents of a WebBook instance can be placed inside a Web site's directory and are directly readable by a Web browser using the URL for that directory
  3. the contents of a WebBook instance can be placed inside a local directory and are directly readable by a Web browser opening its index.html or index.xhtml topmost file
  4. each individual resource in a WebBook instance, on a Web site or on a local disk, is directly readable by a Web browser
  5. any html document can be used as content document inside a WebBook instance, without restriction
  6. any stylesheet, replaced resource (images, audio, video, etc.) or additional resource useable by a html document (JavaScript, manifests, etc.) can be used inside the navigation document or the content documents of a WebBook instance, without restriction
  7. the navigation document and the content documents inside a WebBook instance can be created and edited by any html editor
  8. the metadata, table of contents contained in the navigation document of a WebBook instance can be created and edited by any html editor
  9. the WebBook specification is backwards-compatible
  10. the WebBook specification is forwards-compatible, at the potential cost of graceful degradation of some content
  11. WebBook instances can be recognized without having to detect their MIME type
  12. it's possible to deliver electronic books in a form that is compatible with both WebBook and EPUB 3.0.1

Compatibility with EPUB 3.0.1 is a good way to start adoption. Now to see if WebBook catches on. The GitHub repository is here.

    Stylesheets are an ancient idea that are part of an important separation of structure and presentation, and a concept on which the venerated Tim Berners–Lee also apparently worked. Wikipedia [wikipedia.org]:

    CSS was first proposed by HÃ¥kon Wium Lie on October 10, 1994.[19] At the time, Lie was working with Tim Berners-Lee at CERN.[20] Several other style sheet languages for the web were proposed around the same time, and discussions on public mailing lists and inside World Wide Web Consortium resulted in the first W3C CSS Recommendation (CSS1)[21] being released in 1996. In particular, Bert Bos' proposal was influential; he became co-author of CSS1 and is regarded as co-creator of CSS.[22]

    Style sheets have existed in one form or another since the beginnings of Standard Generalized Markup Language (SGML) in the 1980s, and CSS was developed to provide style sheets for the web.[23] One requirement for a web style sheet language was for style sheets to come from different sources on the web. Therefore, existing style sheet languages like DSSSL and FOSI were not suitable. CSS, on the other hand, let a document's style be influenced by multiple style sheets by way of "cascading" styles.[23]
