• Prolog Parser
  The prolog parser takes a transcript (written in XML) and the corresponding DTD file as input, parses all the events that are described within the transcript, assigns appropriate time intervals to them, and stores the result as a trace.
   
• Trace Analysis Software
  People who want to use the Trace Analysis Software and are not studying or working at the Vrije Universiteit can contact Lourens van der Meij or Tibor Bosse for a copy of the software.
   
• Document Type Definition
  To work with XML annotated files you need a DTD (Document Type Definition) file that describes the markup syntax of the XML file. The DTD file for the Dog Cognition experiments illustrates important concepts for annotating behaviour of dogs that can occur in the experiments.
