Over the past week I’ve posted excerpts from a very insightful email exchange between Bill McCoy of the IDPF and Sanders Kleinfeld of O’Reilly (first piece here and second piece here). This is the final installment of that thread and we pick it up where Bill suggests a tighter connection between the simple ebooks of today and the richer ones we’re likely to see in the future:
Distinguishing ebooks from apps
Bill: There’s a continuum between non-enhanced text-centric publications and enhanced interactive publications, not a dichotomy.
Sanders: Well, I think you always need to draw a line somewhere between “ebook” and “app”. That’s true right now, in that ”Finding Nemo: My Puzzle Book” is an app and “Does the Noise in My Head Bother You (Enhanced Edition)” is an ebook. My current prediction is that in the future, the line is going to be drawn such that more and more content slides over to the “app” side, and more specifically that more of these will be web apps, as opposed to the native iOS/Android book apps that predominate now. It sounds like you believe the reverse will be true, and you may very well be right.
Honestly, I just want publishers to put out more and more awesome, innovative digital content, preferably crafted using open Web standards. If it’s easier for them to do it using EPUB 3, then I’m all for it. But if circumstances militate against this route, as they do now, I’d rather see them explore web apps than throw in the towel.
Bill: Your argument would seem to imply that if you need to add a video or an equation visualization widget to an eBook you should move to the “other side” and build a web app instead. That’s not realistic for publishers. A lot of content will bring limited enhancements to largely text-centric linear documents.
Your own “HTML5 for Publishers” may even be a good example. It obviously has a lot of enhanced capabilities. It can live as a web app but as far as I know it doesn’t, or if it does it isn’t the normal way it’s consumed. And if you did make it into a standalone web app you’d have to code up a whole skeleton of supporting infrastructure around it, using non-standard tools. Do you really expect every publisher to do this for every title?
Sanders: I disagree with this point, in that it implies that in circumstances where you want to add a video or another widget, it’s necessarily a lot of additional work to do a web app than an EPUB 3. There’s no reason why you can’t take the very same content that you zip up in an EPUB 3 and instead post it wholesale on the Internet as a website. And if you did want to add additional supporting infrastructure for a title, it could likely be reused for other titles; I don’t think it’s true that publishers would have to start over from scratch for every book.
Bill: And a whole lot of content is going to be less enhanced than “HTML5 for Publishers” (since after all it’s subject is interactivity). I think any title being created today with iBooks Author and Habitat will be doable with off-the-shelf EPUB 3 based tools and deliverable to multiple off-the-shelf EPUB 3 reading systems within the year.
Sanders: That’s great. I really do hope that proves to be true.
Closing the gap between HTML5 and EPUB 3 support
Bill: We are still in the initial rollout stage of EPUB 3 support. As EPUB 3 proliferates, there’s no reason for EPUB 3 support to continue substantially lag browser support.
Sanders: It’s great to hear you say that. I do acknowledge that my perspective on this debate may be overly biased by my experiences as an ebook developer for the past year, who has been greatly frustrated by the current state of the ereader landscape’s support for HTML5 features and how much it’s limiting innovation in the EPUB (and Mobi) space. But I know you’re traveling all over, fiercely advocating for EPUB 3, HTML5, and open Web standards, and have a much better perspective than I do where things are headed, and how fast we’ll get there. I’m not sure what you’re advocating publishers do in the meantime, though. Should they just wait? Should they predicate their digital publishing initiatives on whether NOOK will support Canvas in the next year?
I have a great deal of admiration for the IDPF and their mission to achieve broad-based support for EPUB3, and I most certainly regret that anything I said may have diminished the value of this goal or argued against it. At the same time, I hope it’s understandable why publishers might view putting all their eggs in the EPUB 3 basket to be undesirable at this time.
I believe this statement by Bill was one of the most important ones in the whole discussion:
As EPUB 3 proliferates, there’s no reason for EPUB 3 support to continue substantially lag browser support.
That lag is one of my biggest concerns as well and why I feel publishers should focus on HTML5 itself and not something else that’s built upon HTML5 (and therefore requires more time for development and adoption).
What’s your opinion? Will the gap between HTML functionality and EPUB reader support for those features shrink or will there always be a lengthy delay in the latter’s ability to keep up with the former?
