"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." Bring it on! Of course for me to take advantage of it, both Adobe and Sony have work to do. So my real expectation is that "later this year" means, at best, "sometime much later".Thanks for the info, Hadrien! |

OK, I removed Adobe DE 1.0 and installed 1.5 instead. Had to create an account to launch this beta using their new ID system. The software detected that I'm french, and I automatically get the french translation.
I can see that a few bugs got fixed (in DE 1.0, it used to display a blank page every now and then if I directly opened a file instead of adding the file to the library), and some of the new features are pretty good. I really like the idea of the page map feature for example: Quote:

Hadrien,
Your book is slow because the chapters are not splitted into separate flows. While technically it does not violate the spec (and it passes epubcheck), it places very high processing burden on the reading system. It will only be worse on the handhelds, which might not even be able to load the whole book because of the memory/CPU constraints. This is a common problem and Digital Editions beta detects this. When you see a slowdown, check "Item info" and if you see this message: "Document contains a resource which is too long", there is a good chance that this book won't be fully readable on handhelds.

I've just tried opening War and Peace in DE 1.5 (that's usually my worst case scenario) and although it gets pretty slow when you open the main content, I don't get the warning. I could make some work on the way we generate our files, but in some cases, we'd still get very long flows (for example a book from Proust or Ulysses from James Joyce). Edit: Maybe you did not translated the alerts ? |

Hadrien,
You are probably right, I do not think we are fully done with translating, so it might just not show up in French. And it is not really one vs. multiple files, it's just the size of a single flow. Peter |

But for example, a book from Proust, is at best, divided into two parts. A single sentence can last through multiple pages. How can the content producer deal with such a file ? |

Peter, a very big MobileRead welcome to you!
It's great to have someone associated with DE willing to offer us a bit of advice! We wouldn't want you to feel pressured, but please do know that we appreciate it. |

I can understand why it's much easier to implement the parsing of the whole file instead of using a buffer for example. But it's gonna be very complicated to ask every content producer to divide the flows this way between multiple files. In my case, I can do it for most books, but I can think of a few books where it wouldn't be possible (a page break is automatically added between different flows right ? There's some books with no page breaks at all). Maybe some pre-processing (if a flow is too long, divide it into multiple flows without page breaks between the flows) on the reading system would be possible ? |

All I really want to say is that it won't work all that great with the current version of our software. Moreover, it will always work best if a book which has natural breaking points is broken up into separate flows. At some point we'll figure out how to deal with books like cannot be easily broken into chapters as well, but we have to start somewhere. Quote:

I'll see what I can do about the size of the flows, it'll make things a bit more complicated for the NCX file too. Now for a very different issue: in our epub books on Feedbooks we usually have links pointing to some other epub files. At the beginning of the file, we link to other books from the same author, and at the end of the book we link to recommendations. If you click on one of those links, it'll open the browser, download, and then open the file in DE. It would be a much better process if it somehow detected that this link is for DE, and that it should add the new download to DE's library. A very simple solution for this would be to use a rel tag, like in some microformats: http://microformats.org/wiki/rel-design-pattern |
