Hi Christian,

but it just allows to export graph in a static way, so spells of GEXF (and so the dynamic) are not set. It can used to make a snapshot of a graph.

GEXF has a cumulative approach of the dynamic where graph contains all informations about dynamic, while GraphStream has a step-by-step approach where graph contains only informations of the current time. So it's not trivial to  reify the whole dynamic of the graph in GraphStream (to export it into GEXF for example) because this is not in the GraphStream philosophy. However, we have starting create object like Timeline ( to help filling the gap between these two models.

GEXF sink should be fully operational one day .... But maybe it can already help you !

Dear Yoann,

thanks for your quick answer.

I am aware of that project. It looks like this tool does not handle steps properly. Although gs-gephi dynamically creates a graph in Gephi, it is not possible to store this graph with the option "dynamic" in Gephi :-(

Looks like I have to program such a converter by myself. But thanks anyway as I wanted to know whether such a tool exists or not.

Kind regards,

Hi Christian,

I don't know if such tool exists, especially when dynamic graphs are involved.

However you may be interested in a project from last Google Summer of Code where an online interconnection between GS and Gephi has been implemented using the Gephi's Graph Streaming Plugin.

A video is worth an explanation:

The project itself:
