The GephiPlugin Developer Workshop presents an introduction to Gephi, an open-source network analysis tool built on the NetBeans platform, focusing on modular architecture and plug-in development. It emphasizes the need for plug-ins to extend Gephi's functionality for various network types and provides detailed guidance on building and managing these plug-ins within the IDE. The workshop also highlights the Gephi Toolkit, which packages essential modules for use in Java applications without a graphical interface.

13. Introduction to GephiGephi has… A website, a wiki, a bug tracker, a forum and a mailing-list

14. A modular and extensible architecture

15. A codebase of ~180K lines of code

16. Long-term plans and roadmap

17. A ManifestoGephiPlugin Developer Workshop

18. Introduction to GephiGephi focus on… Performance, Usability and Modularity (and Stability!)

19. The platform, easy to use and extend

20. Networks. No diagrams or other visualizations.

21. Standards and open innovationGephiPlugin Developer Workshop

22. Introduction to GephiThe Platform’s vision Modular architecture The secret sauce for a sustainable code

23. Interoperability Use, improve or create standards

24. Integration Be exigent with UI, installation, platforms

25. Open and transparent Ideas and features come from the community

26. Public good Is and will remain open-source

27. Documentation Provide tutorials and rich JavadocGephiPlugin Developer Workshop

28. Why building plug-ins? Networks are everywhereSocial Networks, Biological Networks, Power grid, Software, Innovation… The complex world produces networks to visualize and analyze.Gephi is a generic software for all networksThe variety of networks, data sources and algorithms is huge. Gephi can’t support all of them by default so we need plug-ins.GephiPlugin Developer Workshop

29. Why building plug-ins? It’s easy to build and updatePlug-ins are easy to create and release. Development is integrated in Netbeans IDE. No JAR hell. Easy to release new version through Gephi’s website. Hack vs Plug-insPlug-ins are an incentive to build sustainable modules and share them. One can always take the source code and hack it to get things done but there is an real advantage to built on top of clean APIs.GephiPlugin Developer Workshop

31. Netbeans Platform"The NetBeans Platform is a generic framework for Swing applications. It provides the "plumbing" that, before, every developer had to write themselves”Quick StartDescription and tutorialsAPI IndexGephiPlugin Developer Workshop

32. Netbeans PlatformGephi is built on top of Netbeans Platform.

33. So, development is fully integrated in Netbeans IDE:

34. Download Gephi’ssources

35. File > Open Project in Netbeans

36. Browse existing modules or create new

37. Run Gephi. Click on Run!GephiPlugin Developer Workshop

38. Netbeans PlatformIn a few words…Netbeans Platform provides to Gephi the module system, the window system, the localization system, the preferences system and more…

39. Gephi development is integrated within Netbeans IDE.

40. A Netbeans Platform application (like Gephi) is basically a suite of modules.

41. Each module has a title, a description, a version, an author and hopefully a well defined role in the application.

42. Modules expose public APIs and depend on each other (without circular dependencies).GephiPlugin Developer Workshop

59. Visualization APIRead more on the JavadocGephiPlugin Developer Workshop

60. Gephi APIs Each API has a role and a set of public packages other modules can use

61. Consult the Javadoc to see what an API does and browse classes

62. While the software evolve, APIs remain backward compatible

63. When we do changes on APIs, we wrote changes in the “API Changes” section on the Javadoc front-page
