EPUB Best Practices

We’ve created a Developer Center area for Digital Publishing. What does this mean? Well, it’s a lot of technical information around EPUB, Adobe Digital Editions, and ADEPT. Of particular interest today is also the “Best Practices” Guide. Those best practices will help publishers create EPUBs that work great across a whole spectrum of devices.

Anyway, the Best Practices, and lots of other useful information can be found over at the Developer Center:

Digital Editions Beta2 Released

Adobe is pleased to announce the release of the second Beta version of Digital Editions 1.5.

You can find it here:

The Beta is an opportunity for customers to test and provide feedback to Adobe on new features and compatibility with their digital publications.

The key feature of this second Beta release is that we have enabled the “Setup Assistant”. This walks the new user through the steps of authorizing their computer. With this assistant, you can also, optionally, decline to authorize your computer. Adobe very very strongly discourages this. We feel that you should *always* authorize your computer. More on this below.

The key feature of Digital Editions 1.5 is the addition of enhanced DRM support that provides “content portability” across computers and devices that you authorize with your Adobe ID. (Note that this portability is available ONLY if you authorize your computer).

Note: You should be aware that this beta release includes an enhanced version of DRM (Digital Rights Management) protection. If you plan on using Digital Editions for mission critical work, please consider using Digital Editions 1.0.

Key features of the enhanced DRM include:
- Ability to convert a user’s content to a “Named Authorization” license, enabling them to be backed up, copied and read on other computers or devices
- Authorization of end users’ DRM protected content with an Adobe ID (if authorized)
- Writing the secure license into the document
- Existing content is migrated to the new system and newly downloaded content is automatically converted when it is downloaded
- Content portability applies to both PDF and EPUB documents (again, only if the computer is authorized).
- Resulting documents can be copied just like any other file (if both computers are authorized)
- Documents can be opened on any computer or device which has been authorized by the owner
- The number of machines that can be authorized is controlled by the amount set by the Authorization server (up to 6 computers and 6 devices)
- We have added functionality within Digital Editions 1.5 to support mobile devices. At this time we are working hard on rolling out support for the actual devices which work with Digital Editions, which should become available later this year.
- The number of machines on which a document can be viewed is limited by the number of authorized machines, unless the document has been limited to a single machine by the publisher

Note that authorization with an Adobe ID is no longer required in 1.5, but is *strongly* recommended. If you do not authorize your computer, your content will, as in Digital Editions 1.0, be locked to the computer to which is was downloaded. Adobe feels very strongly that all users will be best served by authorizing their computers. Adobe Digital Editions does not use the ID for any purpose other than enabling portability by linking you and your books. The ID is not used for any other purpose, public or private. Please see Adobe’s privacy policy here.

Publishers and vendors should note that this release does not alter the fulfillment of ebooks so existing ecommerce workflows are not affected.

In addition to the DRM enhancement, this release of Digital Editions also
Adds support for Mac OSX 10.5 (Leopard)
- Fixes a bug in which double-byte (e.g. Asian, some European) users could not use Digital Editions
- Adds support for users whose My Documents folder is mapped to a network drive.
- Improved PDF support, including more complete support for the Adobe transparency model
- Support for named pages in PDF (e.g. i, ii, iii, etc.)
- Page map support in EPUB so that there is a mapping between the reflowed screens and the paper copy of a book
- Adds support for multiple books per ETD fulfillment
- Miscellaneous user interface improvements and bug fixes
