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)
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
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?
