Venetia A. • For some reason the link isn't appearing in my post above - please click here to watch the video http://mpsltd.wordpress.com/2011/08/30/an-epub-3-sample/

Venetia A. • Glad you liked it, Don. I certainly agree that collaboration is vital to speed adoption up, but I'm afraid we can't share the actual file and coding publicly. This was a collaboration between our EPUB, HTML and scripting experts and a lot of work went into creating the sample, so it wouldn't be fair on the team to do that. I hope you understand. If you have samples that you have worked on though, why not create a video demo and post the link here? We'd love to see what you are working on.

Lynn Manning R. • The video was interesting but the audio wouldn't turn on (never happened before) Been in ebook conversions since 1999 - (I don't do the conversions on SmartSite.com - but Amazon/Kindle lists my company among 11 others worldwide). That's a boost and we get lots of questions re: .epub but most self-published authors don't have the funds to pay for much more than simple text.

Chris W. • Don, if you have examples you're working on, may I suggest publicizing the link elsewhere (like on Teleread or another digital publishing/layout blog) instead of here? I'm not sure why Macmillan would refuse to share HTML/CSS/JavaScript coding as if it were highly secretive, competitive knowledge, but this certainly seems like a poor platform for others to share their work.

That said, well done to Macmillan's team for a really nice, if neutered, demo.

Eric F. • Please clarify whether this is a fully-compliant EPUB 3 file being demonstrated or if it is a demonstration of EPUB 3 capabilities now available within iBooks, which is still currently an EPUB 2.0.1 reading system. At this point in time, the EPUB 3 spec is still not finalized and Apple has not announced EPUB 3 support within iBooks. Also the working group is still reviewing fixed layout books and there is nothing about that in the spec. This is an iBooks only implementation. If these are truly fully compliant EPUB 3 files, would you be willing to share them with the working group for testing purposes?

Sebastien D. • Too bad that the video was removed: any reason for it?

bhuvana R. • I've watched this video, very nice and informative....

Ana V. • I tried to view the video, but it said it was removed. Can it be reposted?

Len F. • Sebastien, I suspect that the reason was negative feedback in this forum and on Twitter. Venetia Ansell of MPS has repeatedly refused to provide the source files to verify that the demo was actually done with EPUB 3. Other commenters have noted that the video demonstrates features that a) Are already supported by Apple's iBooks eReader extensions, and b) Haven't even been defined within the EPUB 3 specification. For my part, I thought that large parts of the demo video looked awful.

Venetia A. • Just got back online after a few days – so many comments... I’ll try to answer each of your questions over the next couple of days. Sorry that we had to take the video down. We were bowled over by how popular it became – it was as we said in the blog post only a first cut and a lot of people commented on the audio issues and low quality so we decided to remove and release a more polished version which better demonstrates EPUB 3 capabilities. Get in touch if you'd like me to let you know when it’s ready. I'll post it here again of course too.

Len F. • Don, one place to start would be to look at an open source EPUB editor like Sigil (https://code.google.com/p/sigil/). One of the biggest points of difficulty with figuring out how EPUB works is that it's not a single file format, but rather, a group of files with different components that do different things. You can experiment with creating your own EPUB files, and then see how they actually work, and you can open non-DRMed EPUBs in the editor and see how they're built. There are tons of non-DRMed eBooks at Project Gutenberg (http://www.gutenberg.org/) and the Internet Archive's Open Library (http://openlibrary.org/), which also has a very nice open-source eBook reader.

Another good place for information is the IDPF Forum. The IDPF is the organization that manages and ratifies EPUB standards. For example, the EPUB 3 proposed specification is at http://idpf.org/epub/30/spec/epub30-overview.html .
