We recently attempted to explain the new ePub standard and did a pretty good job of simplifying it for the lay audience if we do say so ourselves. However, a reader’s comment suggests we may have oversimplified it. He introduced the concept of “wrapping” ePub in proprietary shell.

What does that mean and why is it important to you?

The ePub (short for “electronic publication”) standard, we explained, was designed to create an open, one-size-fits-all format. We said that Sony was planning to scrap its proprietary anticopying software in favor of ePub, enabling users to read e-books on any reading device that supports the ePub standard.

Well, yes – and no. Here’s what a correspondent wrote:

“Unfortunately, Sony’s version of ePub, as currently described, will be wrapped in Sony’s DRM, so books downloaded to Sony’s e-reader will not be readable on other devices. ePub does not necessarily mean open, which should be the goal of IDPF and the reading community.“

“DRM” stands for Digital Rights Management, a long way of saying controlled or restricted access to digital content. Proprietary, in other words. Kindle is an example of a proprietary, closed standard.

We referred the question to Michael Gaudet, who frequently unpacks technical complexities for us, and here is what he had to say to our commenter:

What I think you’re asking for is a world with no DRM. While you may see it as unfortunate that Sony isn’t as forward thinking as you’d like, I’m sure Sony and the IDPF are trying to be as realistic as possible in accommodating the ebook market’s suppliers: publishers.

ePub has always been formulated with the anticipation that retailers could wrap it in DRM if they needed to, and many publishers ask for DRM and won’t retail ebooks without it. Each ePub retailer needs to consider how to solve the DRM requirements for publishers and customers, and it’s never going to please everyone.

The biggest publishers who are still actively specifying DRM controls are members of the IDPF and they made these demands in standards meetings for the ePub format, and retailers like Sony and Content Reserve saw what’s coming down the road well in advance of their customers. It would have been suicide for Sony’s ebook store to ignore all the content from publishers who require DRM at this time just because it’s fashionable to bash DRM.

It’s unknown yet whether Sony’s ebookstore ePub implementation will be readable on other devices, but chances are that it can be, depending on the other devices’ software to unlock DRM from multiple vendors. It’s highly likely Adobe’s Digital Editions could support Sony’s ePub in the future, and if that’s possible, then so will other reader platforms that acknowledge ePub.

When customers choose to buy non-DRM books from other retailers that offer them, like Fictionwise, the Sony device is a very welcoming platform for ePub, and I think that’s probably more important than Sony’s store right now. The opportunity exists to read ePubs with or without DRM, and that’s better than where we were a year ago.

Obviously, ePub is not so white, and DRM is not so black. We hope you can live with shades of gray until a true One Size Fits All Standard rules all digital content.
