  • Today we are working within the limitations of ePub 2.0.1 (2010) The fixes for some of these limitations are currently out as proposal for EPUB Open Container Format (OCF) 3.0 :aligned with HTML5… plus inclusion plans for audio, video, MathML, text-to-speech (volume, speed, pitch, rate, lexicon pronunciation dictionary), fonts (Open Type and WOFF), syncing audio to text, citation via CFI (canonical fragment identifiers [ICK!!]), integration of CSS2.1 (and limited bits of CSS3)
  • Philosophy – write once/read anywherelots of devices/same filescreen agnostic… screen flow regardless of size>>> which means a design-rich layout is NOT guaranteed, not even likely… style as "hints", not as necessary - get over it

  • (NOTE: still pending full adoption, and then needs full vendor/hardware/software take-up … so likely 18-24 mos away) SO > consider ePub as moving target (like a browser), not locked (like a gadget)

  • In an ePub package an optional file with the reserved name rights.xml may be included within the META-INF directory at the root level of the container file system.This file is reserved for digital rights management (DRM) information for trusted exchange of Publications among rights holders, intermediaries, and users. If the META-INF/rights.xml file is present, its contents should be only namespace-qualified elementsThe rights.xml file must not be encrypted.If you need a rights file for royalty, loan period, limited plays, etc deal directly with the vendor you will be with.(sample DRM Rights.xml and signatures.xml on Jump Drive)

  • clean valid html 2 / xhtml markupavoidance of self-closing tags where possible for mobi devices (Amazon/OverDrive) … >> calibre will *fix* a for you by auto-adding an opening when you export to a mobi device… don't sweat it.Character support… get the unicode right… but don't expect all character sets and fonts will actually work No support for MathML… so equations/symbols as bitmap or svg images
  • BOM = byte order mark
  • size of picture… both for size of file, but also with different device screen sizes … how to deal with resizing?how text wraps around image? (inline only for sure, *maybe* "float" will work )Talk about the sample B&W line drawing graphic novel from Overdrive every page is full graphic, download is 21 MB for 100 pages even though everything as picture>>> the one way to have absolute control over layout..
  • DOC to HTML to Calibre (lots to clean up in HTML bloat- calibre dodges)DOC to ODT (Open Office) to Calibre (less to clean up)DOC to HTML to DREAMWEAVER (use the clean MS HTML command) >>>>>>>>>> Sigil/CalibreWIN Word 2010 ONLY - install Aspose.Words for Microsoft Word >> EPUB format will be listed in the Save As dialog
  • IPPF validator not functional in Jan 1012… but expect it will be the best in the long run… as from the folk who write the standard
  • ePub3 spin with fixed layout

ePubs-RollYourOwn(for_supercon2012) ePubs-RollYourOwn(for_supercon2012) Presentation Transcript

  • ePubs in (early) 2012 Walter Lewis & Diane Bédard OLA SuperConference 2012
  • Standards? What is ePub? spec defined by IDPF - International Digital Publishing Forum Who is IDPF? adobe, google, overdrive, kobo, sony, world blind union, random house, daisy etc … a trades group, not a standards group PREVIOUS - ePub 2.0.1 (2010) CURRENT - ePub 3.0 (Oct 2011)
  • ePub2 Philosophy write once/read anywhere lots of devices/same file screen agnostic…  screen flow regardless of size (aka Dynamic Layout)
  • Scholarly?  foot notes VS end notes  citation?  anchors for a reference?  embedded milestones to cite from?  need for back links (not there yet)
  • ePub3 Philosophy packaged HTML content  audio, video, objects, colour fixed layout – working group tablet-like devices (high end)
  • ePub3  incorporates features defined by CSS3 Modules and introduces EPUB-specific CSS constructs.  defines a restricted subset of SVG 1.1  defines a set of extensions to the W3C HTML5 document model that Authors may include in XHTML Content Documents.  requires XHTML Syntax of HTML5 (5 unfinished)  scripting and form support are optional … a conformant Reading System might not be a fullyconformant HTML5 User Agent
  • ePub3  It is highly likely that this will render obsolete the current crop of "one-trick pony" light ePub readers (sony, kobo etc)  Enter the tablet… full colour, full motion, add apps, multimedia.. Moved beyond “just the book”
  • iBooksAuthor (.ibooks file) Apple extension (proprietary) iPad running iBook app fixed layout (no re-flow) accessibility: audio vs. font size targeting textbook market distribution/marketing rights?
  • DRM (don’t really mean it?) Four main ebook DRM schemes at present:  Adobe's Adept DRM (overdrive, sony)  Apple's Fairplay DRM (ibook)  Barnes & Noble's DRM (nook/kobo)  Amazon's DRM (kindle) …and “removers” readily available ;-)
  • Structure of OPF (why you want to use a packager)
  • Xhtml elements
  • Apps we suggest Software (mac/win/linux):  Calibre:  ePub Convertor and packager, epub reader  Sigil:  a dedicated EPUB editor  Adobe Digital Editions:  ePub reader, DRM tester (no linux)  Dreamweaver or any clean markup editor
  • Structural thoughts #1  reader app has driver’s seat, will show all content and likely ignore some design  XHTML and CSS **MUST** be UTF-8 or UTF-16 BOM so make sure your editor of choice does this /ensure you SAVE as this format  supply all elements (internal to pub package) , not externally linked
  • Structural thoughts #2  image element (inline)  formats allowed are .gif, .png, .jpg, .svg  alt tag REQUIRED  object element for anything else  (very weak support for this element) Optimal image sizes (OPTIMIZE for WEB)
  • Optimal image sizes  reminder to OPTIMIZE for WEB  cover images:  590 pixels wide x 750 pixels high  resolution should be 72 pixels per inch (ppi)  color images saved in RGB colour space  format can be JPEG, GIF, or PNG.  Max widths for inside images:   Small mobile screens - assume 320 px wide dedicated readers - assume 590 px wide
  • Options: Start with a .DOC Save as HTML
  • MS:HTML vs. the real stuff
  • Options: Start with .PAGES Images: FLOAT vs. INLINE
  • ePub with .PAGES
  • Build with
  • Validators: check your "finished” package FlightCrew (http://code.google.com/p/flightcrew/) better tool...download & install Mac, Win, Linux threepress epub validator (http://threepress.org/document/epub-validate) online but often unclear error messages Other Validators: xhtml validator (http://validator.w3.org) idpf validator (http://validator.idpf.org)
  • Packaging it up: CALIBRE
  • iBooks Author (NOT an ePub)
  • iBooks Author: Sales/distribution rights?
