  22       <div class="date">10th August 2012</div>
  23       <div class="body"><p>In <a href="http://www.docbook.org/">docbook</a> one can specify
  24 the language used at the top, and the processing pipeline will use
  25 this information to pick the correct translations for 'chapter', 'see
  26 also', 'index' etc.  And for most languages used with docbook, I guess
  27 this work just fine.  For example a German user can start the document
  28 with &lt;book lang="de"&gt;, and the document will show up with the
  29 correct content with any of the docbook processors.  This is not the
  30 case for the language
  31 <a href="http://people.skolelinux.org/pere/blog/Free_Culture_in_Norwegian___5_chapters_done__74_percent_left_to_do.html">I
  32 am working with at the moment</a>, Norwegian Bokmål.</p>
  33
  34 <p>For a while, I was confused about which language code to use,
  35 because I was unable to find any language code that would work across
  36 all tools.  I am currently testing dblatex, xmlto, docbook-xsl, and
  37 dbtoepub, and they do not handle Norwegian Bokmål the same way.  Some
  38 of them do not handle it at all.</p>
  39
  40 <p>A bit of background information is probably needed to understand
  41 this mess.  Norwegian is not one, but two written variants.  The
  42 variants are Norwegian Nynorsk and Norwegian Bokmål.  There are three
  43 two letter language codes associated with these languages, Norwegian
  44 is 'no', Norwegian Nynorsk is 'nn' and Norwegian Bokmål is 'nb'.
  45 Historically the 'no' language code was used for Norwegian Bokmål, but
  46 many years ago this was found to be å bad idea, and the recommendation
  47 is to use the most specific language code instead, to avoid confusion.
  48 In the transition period it is a good idea to make sure 'no' was an
  49 alias for 'nb'.</p>
  50
  51 <p>Back to docbook processing tools in Debian.  The dblatex tool only
  52 understand 'nn'.  There are translations for 'no', but not 'nb' (BTS
  53 <a href="http://bugs.debian.org/684391">#684391</a>), but due to a bug
  54 (BTS <a href="http://bugs.debian.org/682936">#682936</a>) the 'no'
  55 language code is not recognised.  The docbook-xsl tool chain only
  56 recognise 'nn' and 'nb', but not 'no'.  The xmlto tool only recognise
  57 'nn' and 'nb', but not 'no'.  The end result that there is no language
  58 code I can use to get the docbook file working with all of these tools
  59 at the same time. :(</p>
  60
  61 <p>The correct solution is to use &lt;book lang="nb"&gt;, but it will
  62 take time before that will work with all the free software docbook
  63 processors. :(</p>
  64
  65 <p>Oh, the joy of well integrated tools. :/</p>
