GEXF for Dynamic Graphs?

[Dylan Hutchison <dhutchis AT stevens.edu>]

Hi there,

Back in January an email went around on using the Timeline class plus FileSinkGEXF to record a stream of graph events to a Timeline object, and at a later time, write out all those events to a GEXF file via FileSinkGEXF.  Since then, Timeline has seen good development and has really nice playback methods. But, there still does not appear to be any way to save a Timeline (or Graph in general) to a GEXF file.  

Does anyone have any suggestions on how to save a dynamic graph to a GEXF file?

Ideally, I would like to write something like this:

Timeline timeline = new Timeline();

Graph g = new SingleGraph("data");

timeline.begin(g);

addTonsOfDynamicGraphEvents(g);

timeline.end();

//timeline.playback(); // Side note: Really useful method for playing back to a Graph g

// Can we play back to a file instead?

FileSinkGEXF fsinkgexf = new FileSinkGEXF();

fsinkgexf.begin("output.gexf");

fsinkgexf.playbackTo(fsinkgexf, "output.gexf"); // made up method

Thanks,

Dylan Hutchison
