Gaphor – Technical Documentation

Gaphor is a UML and SysML modeling application written in Python. It is designed to be easy to use, while still being powerful. Gaphor implements a fully-compliant UML 2 data model, so it is much more than a picture drawing tool. You can use Gaphor to quickly visualize different aspects of a system as well as create complete, highly complex models.

This documentation is aimed at those who would be interested in making contributions to Gaphor. For download instructions, tutorials and how-to’s, please visit the Gaphor Website.
