The ix modeling platform (ixmp) is a data warehouse for high-powered scenario
analysis, with interfaces to Python and R for efficient scientific workflows and
effective data pre- and post-processing, and a structured database backend for
version-controlled data management.
In the name, “ix” stands for “integrated” and “cross (x) cutting”.

The MESSAGEix modeling framework is built on top of the ix modeling platform.

This repository contains the core and application programming interfaces (API)
for the ix modeling platform (ixmp), as well as a number of tutorials and
examples for a generic model instance based on Dantzig's transport problem.

Documentation

Complete documentation of the ixmp API is available for current and past versions at: https://docs.messageix.org/ixmp/.
This includes:

Other forms of documentation:

  • The online documentation is built automatically from the contents of the
    ixmp GitHub repository.
  • For documentation of a specific release, e.g. v3.2.0, use the chooser in the bottom sidebar.
  • For offline use, the documentation can be built from the source code.
    See doc/README.rst for further details.
  • The MESSAGEix API documentation links to the ixmp documentation in many places, for convenience.
