Anyone know where the non-DRMed Mobipocket format is described?

Nikolay Pultsin, the FBReader developer, has indicated he'll support that format if only he could get his hands on the specs.

The only things I can find are tools for creating a title in Mobipocket format, not creating a tool for reading it.

Which leads me to ask, Are there any (other) e-readers that read Mobipocket format?

Okay, I don't know much about this stuff, but I can point you to some info with the hopes that some of it might be helpful. I'm kind of like the blind man shooting at a bottle on the fence. Not likely to break the bottle, but it's fun to shoot! ;)

I can't tell with a quick look, but there is some information for Mobipocket developers here... http://www.mobipocket.com/dev/default.asp including some of the book creator software (maybe with documentation on the format?), and the DOM (Document Object Format) http://www.mobipocket.com/dev/article.asp?BaseFolder=prcgen&File=reader_dom.xml.

Unfortunately, that probably doesn't help you read as it might be the code that gets compiled into the final format, so I don't know if it's helpful to you.

I can tell you that "The Mobipocket eBook format based on the Open eBook standard using XHTML can include JavaScript and frames. It also supports native SQL queries to be used with embedded databases" according to http://en.wikipedia.org/wiki/Ebook#Mobipocket

This (http://www.eurocool.com/author/?author=12080) would indicate that it really is an Open eBook implementation:Mobipocket Publisher
Based on standards
- First implementation of Open-eBook specification for PDAs
- Builds a unique cross-platform eBook file format (XDOC PRC)
- Integration with any third party HTML/XML editor
- Support of CSS style sheets

All HTML / CSS tags supported, including

- Images
Support of MetaData
- Displayed by the Reader (eBook info menu)
Support of Guides
- Displayed by the Reader as additional menu items in the navigation menubut of course that doesn't mean it's not extended.

There are in fact now two formats for the content. I have reverse engineered the older one and know most of the tricks of the newer one. Unfortunately i do not know the format of the higher compression.

Bob,

Thanks. I'll make sure Nikolay Pultsin is aware of at least this information.

He's been working on implementing OEB, so that looks like a good-sized piece of the puzzle.

Robert,

I hope you'll share what you know with Nikolay, privately or in a forum. I've expanded the scope of the discussion from the FBReader group at Google, which seems like the most obvious place to contact him: groups.google.com/group/fbreader
