A related package, pyNeuroML builds on this and provides functionality, scripts and modules for reading, writing, simulating and analysing NeuroML2/LEMS models.

pyNeuroML builds on: libNeuroML & PyLEMS and wraps functionality from jNeuroML.

Development process for libNeuroML

Most of the work happens in the development branch. That branch is kept up to date with the development branches for NeuroML 2 and related libraries. See for an overview of the various NeuroML libraries.
