README file for the DocBook XSL Stylesheets
|
||
|
|
----------------------------------------------------------------------
|
||
|
|
|
||
|
|
These are XSL stylesheets for transforming DocBook XML document
|
||
|
|
instances into .epub format.
|
||
|
|
|
||
|
|
.epub is an open standard of the The International Digital Publishing Forum (IDPF),
|
||
|
|
a the trade and standards association for the digital publishing industry.
|
||
|
|
|
||
|
|
An alpha-quality reference implementation (dbtoepub) for a DocBook to .epub
|
||
|
|
converter (written in Ruby) is available under bin/.
|
||
|
|
|
||
|
|
From http://idpf.org

|
What is EPUB, .epub, OPS/OCF & OEB?
|
||
|
|
|
||
|
|
".epub" is the file extension of an XML format for reflowable digital
|
||
|
|
books and publications. ".epub" is composed of three open standards,
|
||
|
|
the Open Publication Structure (OPS), Open Packaging Format (OPF) and
|
||
|
|
Open Container Format (OCF), produced by the IDPF. "EPUB" allows
|
||
|
|
publishers to produce and send a single digital publication file
|
||
|
|
through distribution and offers consumers interoperability between
|
||
|
|
software/hardware for unencrypted reflowable digital books and other
|
||
|
|
publications. The Open eBook Publication Structure or "OEB",
|
||
|
|
originally produced in 1999, is the precursor to OPS.

.epub Constraints
|
||
|
|
----------------------------------------------------------------------
|
||
|
|
|
||
|
|
.epub does not support all of the image formats that DocBook supports.
|
||
|
|
When an image is available in an accepted format, it will be used. The
|
||
|
|
accepted @formats are: 'GIF','GIF87a','GIF89a','JPEG','JPG','PNG','SVG'
|
||
|
|
A mime-type for the image will be guessed from the file extension,
|
||
|
|
which may not work if your file extensions are non-standard.
|
||
|
|
|
||
|
|
Non-supported elements:
|
||
|
|
* <mediaobjectco>
|
||
|
|
* <inlinegraphic>, <graphic>, <textdata>, <imagedata> with text/XML
|
||
|
|
@filerefs
|
||
|
|
* <olink>
|
||
|
|
* <cmdsynopsis> in lists (generic XHTML rendering inability)
|
||
|
|
* <footnote><para><programlisting> (just make your programlistings
|
||
|
|
siblings, rather than descendents of paras)

|
|
|
||
|

|
||
|
|
