Project overview

Project structure

• bpmn_python - main module of project, includes all source code
• tests - unit tests for package
• examples - examples of XML files used in tests
• docs - documentation for package

External libraries used in project

• NetworkX - NetworkX is a Python language software package for the creation, manipulation, and study of the structure, dynamics, and functions of complex networks. We use this library to implement a graph representation of BPMN diagram,
• Matplotlib - matplotlib is a python 2D plotting library. Used to provide simple visualization of BPMN diagram,
• PyDotPlus - Python interface to Graphviz’s Dot language,
• Graphviz - Graphviz is open source graph visualization software. The Graphviz layout programs take descriptions of graphs in a simple text language, and make diagrams in useful formats.

Project requirements

Project is targeted for Python 2.7. We use some built-in modules in our implementation (uuid, minidom, elementtree). Make sure you have installed required external libraries:

• NetworkX,
• Matplotlib,
• PyDotPlus.

Also, make sure you have installed Graphviz on your computer and set up all required system enviroment variables. You can find instructions on Graphviz webpage.
