MPDL 2.0

The MPDL release 2.0 is redesigned so that all important functions (language technology, XML functions) are usable as web applications independent from the eXist software - available as HTTP servlets and fully implemented in Java.

Language technology

The language technology module consists of:

• language technology data (XML data files, Java Berkely DB's)
  • morphology data (ara, eng, fre, ger, gre, ita, lat, nld, zho)
  • dictionary data
• Java source code
• used Java libraries
• web application configuration file (web.xml)

It is available as the web archive file "mpiwg-mpdl-lt.war".
