The visual graph rewriting platform

PORGY aims at designing relevant graphical representations and adequate interactions on dynamic graphs emerging from graph rewriting systems. Graph rewriting systems appear as a powerful formalism to capture and study phenomena occurring in complex systems, such as the evolution of bio-molecular networks, adhoc communication networks or interaction nets.

The ability to act on the simulation of the rewriting calculus will offer the expert a unique mean of interacting with the systems they design and study, turning interactive visualisation of graph rewriting systems into a high-level visual programming environment.

This is a joint work with Maribel Fernandez from King's College London and Hélène Kirchner from Inria. The first version of Porgy was developed thanks to the Inria associate team program (2009-2011) and the ANR grant EVIDEN (ANR 2010-JCJC-0201-01).

Using as a starting point the Tulip system, we aim to develop an environment that will allow us to:

- create a graph using a visual editor;
- trigger a series of transformations on the graph using graph rewriting rules to describe transformations;
- display a sequence of graphs obtained by application of transformation steps, as well as the sequence of rules underlying these transformations;
- design analysis and verification tools to check static and dynamic properties of graphs.

The desired tool will ultimately be used to model, visualise and simulate biological systems as well as to program with graphical languages such as interaction nets.

Porgy (along with Tulip) is released under the LGPL licence. Porgy is built on top of Tulip as a perspective and a set of plugins. Versions 1.X of Porgy are based on Tulip 3.X. Porgy versions from 2.0 to 3.1 are based on Tulip 4.X.

Nightly Builds (may work or not...) of Porgy and Tulip 5.X (with all officially available plugins) based on the latest svn source trees are available below. We also give acces to sample tulip files to be used inside Porgy.

*Changelog*: Binaries for version 3.0 were not properly compiled (Tulip was not compiled with -std=c++11)
