ePub3 and HTML5 – Enhancing the eReader compatibility
Wednesday, November 9th, 2011There are many reasons that eReaders and eBooks are changing the publishing landscape. As with any technology, early generations of software and hardware have led to continuous improvement over time. The technology behind eBooks is no exception.
The new ePub3 standard reveals the scope of ePub in the current technology trend with a move to HTML5 based content and key emerging technological advancements in all means. The ePub3 with HTML5 support provides rich media experience & interactivity, layout enhancements, global languages support and accessibility improvements. So we hope to see all the features like video & audio embedding, metadata, linking, navigation, multimedia, font, scripting, text to speech, dynamic layouts, semantic mark-ups, etc., in an ePub with help of ePub3. This also provides opportunities for application developers to create eBook readers for web and mobile platforms.
While enthusiasts were analysing and trying to understand the specifications, I had an opportunity to work on a sample for the ePub3. As a team, we have been working on all of the ePub3 features currently supported by the iPad. Below are the listings of the samples we have created using the latest ePub3 standards.
Video: Video can now be embedded in eBooks. Video spec: H.264 (a way of encoding video that’s free to use, but not public domain) is video standard right now, but there is a possibility of open standard by end of this year, that may change to another encoding which might be WebM, which is royalty-free.
Audio: Audio passages can also be embedded in eBooks, and ePub3 is better at adopting the current DAISY accessibility standards, making eReaders more useful to visually challenged users.
Interactivity: An interactive ePub can act more like an app than a document, and can include features like pop-ups for images, tables, bibliography references, etc activated by clicking on words in the text.
Global language support: Includes vertical writing, and writing from left-to-right and right-to-left.
Multi-column layout: A feature that will greatly enhance cookbooks and coffee table books.
Hyphenation: This helps page formatting, particularly in justified text, and avoids very tight or very loose lines of text.
Embedded fonts: This provides lot of opportunities to use any fonts in an eBook.
Improved accessibility: The new NAV formats supersedes the NCX format (ePub2) by providing enhanced navigation within the eBook, improving the reader’s ability to jump to specific chapters, pages, and passages.
MathML: A mathematical specification that provides greater opportunities for textbook publishers to convert and publish texts as eBooks and also provides 100% searchable content which was not there in ePub2 where all maths are coded as images.
Compatibility
ePub3 readers will be backward compatible, meaning they will be able to read eBooks created in the ePub2 format. But ePub2 readers will not be able to read ePub3 documents, as there are structural, non-compatible changes between ePub2 and ePub3.
Would like to hear your thoughts on this emerging standard and your experiences that made things work better with ePub3. Please do share your experiences by writing to us at info@ipublishcentral.com
Readers are given the option to search within the book and ensure that they are getting exactly what they are paying for. Up-to date research reports and full volumes of encyclopedias usually only allow for free book previews, through online readers. Access of an entire volume costs the reader, and if the preview shows content that is worthy, readers are indeed wiling to pay a price for it. The new system that is emerging is of “mixed bundling” - offering a product and its components in different permutations to satisfy different consumer needs. In a manner of speaking, your content is no longer just a product, i.e. a book. Today readers are demanding that there are no restrictions on structure and in a way turning your traditional ‘product’ into a service that requires more than just the physical version. Consumers are demanding specifics, and well, today they are getting what they want. Today, content providers give their readers content in the way they wish to consume it. They give them the option of buying part of the content, add supplementary material to the content, allow them to rent content and many more such options. Thus, to some extent curbing the attitude of, “why should I have to pay for something I don’t need/can get free”.
