The text was only available in old paper books, and thus not -easily available for current and future generations. Some of the -people participating in the discussion contacted the author, and -reported back 2013-03-19 that the author was OK with releasing the -short story using a <a href="http://www.creativecommons.org/">Creative -Commons</a> license. The text was quickly scanned and OCR-ed, and we -were ready to start on the editing and typesetting.</p> - -<p>As I already had some experience formatting text in my project to -provide a Norwegian version of the Free Culture book by Lawrence -Lessig, I chipped in and set up a -<a href="http://www.docbook.org/">DocBook</a> processing framework to -generate PDF, HTML and EPUB version of the short story. The tools to -transform DocBook to different formats are already in my Linux -distribution of choice, <a href="http://www.debian.org/">Debian</a>, so -all I had to do was to use the -<a href="http://dblatex.sourceforge.net/">dblatex</a>, -<a href="http://docbook.sourceforge.net/release/xsl/current/epub/README">dbtoepub</a> -and <a href="https://fedorahosted.org/xmlto/">xmlto</a> tools to do the -conversion. After a few days, we decided to replace dblatex with -xsltproc/fop (aka -<a href="http://wiki.docbook.org/DocBookXslStylesheets">docbook-xsl</a>), -to get the copyright information to show up in the PDF and to get a -nicer &lt;variablelist&gt; typesetting, but that is just a minor -technical detail.</p> - -<p>There were a few challenges, of course. We want to typeset the -short story to look like the original, and that require fairly good -control over the layout. The original short story have three -parts/scenes separated by a single horizontally centred star (*), and -the paragraphs do not contain only flowing text, but dialogs and text -that started on a new line in the middle of the paragraph.</p> - -<p>I initially solved the first challenge by using a paragraph with a -single star in it, ie &lt;para&gt;*&lt;/para&gt;, but it made sure a -placeholder indicated where the scene shifted. This did not look too -good without the centring. The next approach was to create a new -preprocessor directive &lt;?newscene?&gt;, mapping to "&lt;hr/&gt;" -for HTML and "&lt;fo:block text-align="center"&gt;&lt;fo:leader -leader-pattern="rule" rule-thickness="0.5pt"/&gt;&lt;/fo:block&gt;" -for FO/PDF output (did not try to implement this in dblatex, as we had -switched at this time). The HTML XSL file looked like this:</p> - -<p><blockquote><pre> -&lt;?xml version='1.0'?&gt; -&lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'&gt; - &lt;xsl:template match="processing-instruction('newscene')"&gt; - &lt;hr/&gt; - &lt;/xsl:template&gt; -&lt;/xsl:stylesheet&gt; -</pre></blockquote></p> - -<p>And the FO/PDF XSL file looked like this:</p> - -<p><blockquote><pre> -&lt;?xml version='1.0'?&gt; -&lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'&gt; - &lt;xsl:template match="processing-instruction('newscene')"&gt; - &lt;fo:block text-align="center"&gt; - &lt;fo:leader leader-pattern="rule" rule-thickness="0.5pt"/&gt; - &lt;/fo:block&gt; - &lt;/xsl:template&gt; -&lt;/xsl:stylesheet&gt; -</pre></blockquote></p> - -<p>Finally, I came across the &lt;bridgehead&gt; tag, which seem to be -a good fit for the task at hand, and I replaced &lt;?newscene?&gt; -with &lt;bridgehead&gt;*&lt;/bridgehead&gt;. It isn't centred, but we -can fix it with some XSL rule if the current visual layout isn't -enough.</p> - -<p>I did not find a good DocBook compliant way to solve the -linebreak/paragraph challenge, so I ended up creating a new processor -directive &lt;?linebreak?&gt;, mapping to &lt;br/&gt; in HTML, and -&lt;fo:block/&gt; in FO/PDF. I suspect there are better ways to do -this, and welcome ideas and patches on github. The HTML XSL file now -look like this:</p> - -<p><blockquote><pre> -&lt;?xml version='1.0'?&gt; -&lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0'&gt; - &lt;xsl:template match="processing-instruction('linebreak)"&gt; - &lt;br/&gt; - &lt;/xsl:template&gt; -&lt;/xsl:stylesheet&gt; -</pre></blockquote></p> - -<p>And the FO/PDF XSL file looked like this:</p> - -<p><blockquote><pre> -&lt;?xml version='1.0'?&gt; -&lt;xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version='1.0' - xmlns:fo="http://www.w3.org/1999/XSL/Format"&gt; - &lt;xsl:template match="processing-instruction('linebreak)"&gt; - &lt;fo:block/&gt; - &lt;/xsl:template&gt; -&lt;/xsl:stylesheet&gt; -</pre></blockquote></p> - -<p>One unsolved challenge is our wish to expose different ISBN numbers -per publication format, while keeping all of them in some conditional -structure in the DocBook source. No idea how to do this, so we ended -up listing all the ISBN numbers next to their format in the colophon -page.</p> - -<p>If you want to check out the finished result, check out the -<a href="https://github.com/sickel/kodemus">source repository at -github</a> -(<a href="https://github.com/EFN/kodemus">future/new/official -repository</a>).
