OEBPS and OCF are two generations of an open-standard format for eBooks, both
built upon HTML, XML and ZIP.

This format is used internally by proprietary eBook tools such as Microsoft
Reader, MobiReader and their respective compilers, and directly by open-source,
open-standard eBook readers such as OpenBerg Lector or dotReader/ThoutReader.
There is also a possibility that this format will be used by One Laptop Per
Child to provide eTextBooks for Third-World Children.

Unfortunately, to this day, there are no open-source tools able to produce
OEBPS/OCF eBooks. Which is, most definitely, a shame. I therefore suggest the
inclusion of OEBPS/OCF import and export filters to OpenOffice. 

The export filter should be able to
* convert a document to either one or several XHTML files (split by, say,
chapter or section, etc. depending on the user's wishes), with their
dependencies (images, style sheets, etc.)
* create a metadata XML-based "package file" containing informations about the
book title, author, subject... as well as the reading order of the split XHTML
files, as per the OCF file format
* for compliance with OCF, add the ODF metadata information
* zip it all.

Conversely, the import filter should be able to open that same format.
