I've created a xslt to do this using the toc.ncx, but just found an ePub which is valid that has a different name for the ncx file, so might be best to work from the odf file. Although most ePub 2s don't use Heading levels but normal p with styles that look like a headings so although braille can be produced it won't be formatted well. To be honest when you open up the ePubs it's quite complicated and only working with the creators of the ePubs to get them to properly format and stick to standard definition for formatting etc. will produce good results. If any one wants to look at the php code I've cobbled together to process ePubs and produce braille via liblouis they are welcome. I'm going via xhtml from the ePubs to dtbook and then into liblouis. I'm in the midst of upgrading to the latest version file2brl from xml2brl on a windows xp server. Also you could look at the DAISY pipeline 2 which has ePub 3 to zedai(DAISY XML) and zedai to PEF using the liblouis engine. this using xproc and xslts, Java etc.

BrailleBlaster may need to handle zipped archives more directly. It looks like liblouisutdml will also need that functionality. It will decide which files to use by looking at the manifest for Daisy or epub or simply chosing the file based on the archive type, as in the case of docx files . There would be a new configuration setting archivetype . For both BrailleBlaster and liblouisutdml there is the problem of combining different files. For example, in epub archives, each chapter is in a different file. How are these combined to get a single file for a book? That is what we would want.

I think we are going to need finer control than we get just by pumping ZIP files through a translate function. Besides, how do we tell LibLouisUTDML what file to translate? That isn't to say you can't add some kind of ZIP handling to the library I just don't plan to use it in that way.

The first seems fairly straightforward. The new semantic action would be extprog and the name of the program would be in the third column. A problem with the second is that a zip archive may contain more than one xml file. This is the case with docx and epub . In the case of the latter, there are likely to be separate files for each chapter. How will the liblouisutdml library know which file to use? How will it combine files to produce a complete book? This feature will probably use the zlib library. I seem to remember that there were difficulties in including it in a dll. It is not in the present ones. John -- John J.
