Version 0.7 launched

I’m pleased to inform the community that we are working on a new Gephi core. As it is explained in recent news about 0.6 beta2 release, we won’t publish an official 0.6 version and move directly to an entire new architecture. Though the 0.6 architecture is pretty stable and has been used for worth case studies (see our Exhibition section or WebAtlas gallery), it doesn’t fit with various new needs, like clustering support and complete dynamic network (DNA) support. The 0.6 core was used since September 2007 from now, mostly in an experimental context. As we receive many positive comments and support, we are adopting a long term view and enter a new development cycle. When increasing quality and modularity of the application, we expect more developers helping and a lower learning curve. Therefore the new architecture will be based on the awesome Netbeans Platform, currently the most advanced open-source framework for large Java modular applications. Plugins development will be eased when based on this framework.

Besides the framework, the most serious change will be located in data structures, with a brand new technology. Developed by us for more than 6 months, the DHNS (Durable Hierarchical Network Structure) is a very efficient data structure for storing hierarchical and dynamic networks. Thanks to this new module, new hard features like a clustering algorithm framework or hierarchical network navigation could be hatched more easily. I am currently writing a paper about these researches.

Other features will be added or improved within 0.7 version, you can have a look on our 2009 roadmap. It’s hard to say now exactly how priorities will be managed but I will publish regularly news about the progress for keeping you informed. For now the top priority is building the new architecture around Netbeans Platform.

Until the end of summer, Gephi project is hosted by RTGI SAS in Paris. Besides supporting our project, they plan to use Gephi daily and thus we have feedbacks and opportunities improving user interface and ergonomics.

Let’s go back to work and build the best open-source network visualization software.
