It's sometimes stated that there's some sort of equivalence between Mobipocket and Kindle format, that Kindles can read Mobipocket files with no problems.
However, in looking over the
Mobipocket file format documentation pages, there seem to be a number of documented features of the Mobipocket platform which are evidently not supported by Kindle. Things like:
JavaScript
Frames
Database access
HTML forms
Several <mbp: ... > tags - the only one Amazon documents for authoring of Kindle content is <mbp
agebreak />. Of course some of the <idx: ... > tags are used for Kindle dictionaries, but Amazon does not document these.
There are also a number of 'best practices' cited there.
To what extent is the information on Mobipocket.com of value for developers of Kindle content? I find Amazon's documentation somewhat lacking, and wonder if anyone has made a systematic effort to go through the Mobipocket documentation and extract the still relevant parts of it to supplement Amazon's docs.
