Technology(1)
  • “Backend” uses XML (one XML file per passage plus “master” XML file),
  • Converted to HTML & SMIL using SAXON XSLT Processor + custom XSLT stylesheets
  • Perl + Sablotron XSLT Processor used for dynamic XSLT conversion

<question mark="3">What were posting stations used for in Russia

beginning in the 13th century?</question>

<transcription clip_begin="3.5" clip_end="21.8">

<para>На Руси начиная с XIII в. на ямских трактах ставились

почтовые станции (ямы), где путешествующие

могли отдохнуть и сменить лошадей. Именно от

этих станций и мерили тогда длину дороги.

Technology (2)
  • XML Stores:
    • “metadata” (audio timings, title, speaker, language etc.) as well as:
    • content (transcriptions etc.) of each passage
  • XSLT allows the passages to be presented in a number of different ways
why was xml used
Why Was XML Used?
  • Unicode – makes handling multiple languages (not all of which use the Latin alphabet) easier
  • Platform/application independence
  • XSLT means same data can be used in different ways
why was realaudio used
Why was RealAudio Used?
  • Has full support for SMIL
  • Allows a lot of interaction with an embedded RealPlayer using Javascript
  • Good quality/compression trade-off
  • Basic Server (was) free
problems
Problems
  • XML files not easy to create or manage for non-technical staff (XMetal helps, but is not the answer)
  • Difficult for Web Designers to use XSLT, though tools are improving
  • Unicode support still a bit patchy on Mac
  • Netscape 6 problems with javascript and embedded objects
  • Latest version of “Free” Real Basic Server now expires after 12 months
future plans
Future Plans
  • Shell for creating/managing XML
  • More XSLT stylesheets to create different ways to navigate XML data
  • Use “standard” XSLT 2.0 instead of Saxon extensions
