Mappa is a Topic Maps engine that is written in Python.

Is it compatible to the Topic Maps - Data Model and provides different backends. Some backends are also usable in a Jython environment.

The API is Pythonic and enables the developer to create and manipulate topic maps easily.

Additionally, Mappa provides the import and export of different Topic Maps syntaxes (i.e. XTM)

Installing

Either you can use the files in the "Downloads" section, or (recommended):

easy_install -U Mappa tm.reader.ctm tm.reader.ltm tm.reader.tmxml tm.reader.jtm

This installs Mappa, and syntax readers for CTM, LTM, JTM and TM/XML. The XTM reader is installed by default from Mappa.

If you just want Mappa and no additional syntax readers, just do:

easy_install -U Mappa

This will install Mappa and a XTM reader for 1.0 and 2.0/2.1 and the tm package.
