SoNIA

SoNIA homepage

SoNIA is a Java-based package for visualizing dynamic or longitudinal "network" data. By dynamic, we mean that in addition to information about the relations (ties) between various entities (actors, nodes) there is also information about when these relations occur, or at least the relative order in which they occur.

The intention for SoNIA is to read-in dynamic network information from various formats, aid the user in constructing "meaningful" layouts, and export the resulting images or "movies" of the network, along with information about the techniques and parameter settings used to construct the layouts, and some form of statistic indicating the "accuracy" or degree of distortion present in the layout. This is all somewhat ambitious, but not impossible.

Authors

SoNIA is currently under development by Dan McFarland? and Skye Bender-deMoll, originally supported by a Research Incentive Award provided by Stanford University's Office of Technology and Liscensing (grant # 2-CDZ-108). Current development is partially supported through a contract with the Center for Studies in Demography and Ecology at the University of Washington with funds from NIH grants supporting the Network Modeling Project (grants # R01 HD41877 and R01 DA12831) But a large fraction of the development and support for this project is volunteered. We would also like to thank James Moody, Ben Shaw, Tom Snijders, Christian Steglich, Michael Schweinberger, Kaisa Snellman, Ozgecan Kocak, John Padgett and many others for their contributions at various stages of this project.

• Modified the batch settings so that only a single picture will be outputted
• Zoom In/Out functionality
• You can now move the graph around to see all of the nodes and arcs, much like a pdf
• .meta and .meta2 file types. These files share the same file name, so the program will now check to see if those files exist and if they do it will attempt to parse them
• The check boxes in 'Users', 'Apps' in the Layout Window. A .meta2 file makes those usable.
• An XML parser. The parser graphs the XML hierarchy.
