MPDL 2.0

The MPDL backend software release 2.0 is redesigned so that important functions (language technology, XML functions) are available as web applications independent from the eXist software - usable 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 (Perseus, CELEX, Lexique with languages: ara, eng, fre, ger, gre, ita, lat, nld, zho)
  • dictionary data (dictionaries: autenrieth, baretti, bonitz, cooper, florio, lewis-short, lidell-scott-jones, salmone, webster)
• Java source code
• used Java libraries
• web application configuration file (web.xml)

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