"BioNessie is a free, state-of-the-art platform-independent BIOchemical NEtworks Simulation and AnalySIs Environment."
Clearly, it is an application on the NetBeans Platform:
"It provides a full user-friendly Graphical User Interface (GUI) which allows the user to import, create, edit and export the biochemical models with the SBML (Systems Biology Markup Language) standard. The unique Concurrent Versions System (CVS) design helps users to keep track of the version history of their SBML models during construction and subsequent modification."
