有关 .ibooks 格式的文档？
我读过 Apple 专有的 .ibooks 格式几乎与 .epub 类似，但我似乎无法在任何地方找到有关它的文档。是的，我有一个开发者帐户。
我需要比较 ibooks 和 epub 格式以查看差异。
I've read that Apple's proprietary .ibooks format is almost similar to .epub but I can't seem to find the documentation on it anywhere. Yes, I do have a developer account.
I need to compare both ibooks and epub format to see the differences.

我知道我来晚了，但我最近对 epub3 和 ibooks 做了一些研究。
因此，首先要记住的是，这些格式只是 HTML 文档的集合，它们被压缩到一个包含资产文件夹（大部分是图像和样式表）的包中。是的，ibook 和 epub3 非常相似，但您需要做一些工作才能将其中一个伪装成另一个。要将 ibook 文件导入 epub3 阅读器，您需要做大量工作来清除其中所有专有的 CSS 和 Plist 功能。
理论上，将 epub3 书转换为 ibook 格式会容易得多，但我还没有成功做到这一点。
无论如何，您可以在我关于 ibooks 文件格式 与 实验配对我在 GitHub 上设置的电子书 git 存储库。我解压了每个文件，创建了目录结构的分解视图，然后漂亮地打印了 XML 和 HTML，以便于查看。
I know I'm late to the party here, but I've been doing a bit of research into epub3 and ibooks lately.
So, the think to keep top of mind is that these formats are just collections of HTML documents zipped together into a package with a folder of assets (images and stylesheets for the most part). Yes, ibooks and epub3 are very similiar, but you need to do some work to get one to masquerade as another. To get an ibook file into an epub3 reader, you'd need to do a lot of work to scrub all the proprietary CSS and Plist features out of it.
In theory it would be much easier to get an epub3 book into an ibook format, but I've yet to successfully do it.
Anyway, you can see a breakdown of the two formats (epub3 and ibooks) in my blog post about the ibooks file format paired with the experimental ebooks git repository I setup on GitHub. I unzipped each one, created an exploded view of the directory structure, and then pretty printed the XML and HTML for easier viewing.
有一个文档“iBookstore 资产指南”，仅当使用出版商帐户登录时在 iTunes Connect 中可用。它不直接涉及 iBooks 作者创建的 .ibooks 格式，而是涉及 iBookstore 出版物的 iBooks 特定信息。
我无法给您链接，因为似乎不允许共享：
有人可能会出于某种原因在某个地方提供某种下载；o)
ibooks 格式不是“开放”的，是由 iBooks Author 生成的，而不是真正手动生成的可修改的。要了解 iBooks Author 的功能，只需使用它或其文档即可。一个简单的答案是：iBooks Author 适合简单、快速、轻松地创建固定版式 iBooks。如果您需要任何特殊功能，例如 JavaScript 交互、动画等，请坚持使用 epub 格式。 iBooks 允许使用某些 epub3 功能，而 epub 文件必须采用 epub2 样式格式（content.opf、toc.ncx、html 文件）。 iBookstore 资产指南和提供的示例是一个很好的切入点。
There is a document "iBookstore Asset Guide", that is only available in iTunes Connect when logged in with a publisher account. It's not directly about the .ibooks-format, the iBooks Author creates, but about iBooks-specifics of publications for the iBookstore.
I can't give you a link, as sharing seems to be not allowed:
Someone might provide a download of some kind for some reason at some place ;o)
The ibooks-format is not "open", is generated by iBooks Author and not really manually modifiable. To see, what iBooks Author is capable of, simply use it or its documentation. A simple answer is: iBooks Author is good for simple, quickly and easily created fixed-layout iBooks. If you want any special functionality, like JavaScript-interaction, animation etc, stick to the epub-format. iBooks allows the use of some epub3-features while the epub-files must be formatted epub2-style (content.opf, toc.ncx, html-files). The iBookstore Asset Guide and the provided samples are a good entrypoint for that.
