Research

• Publishing DocBook 5
  
  Writing semantic documents with DocBook is a simple task today. But when it comes to publishing these documents with appropiate open source technologies or systems other than TeX, are there not much opportunities left. Almost everybody use the stylesheets of Norman Walsh in order to publish DocBook articles or books with XSLT today. This happens because simply there are no other XSLT stylesheets free available.

  In my research I want to check, how much effort is necessary to build other nice XSLT stylesheets by using the latest open source semantic web technologies and tools.
