We released the first version of libgexf, the official toolkit library for creating and manipulating GEXF files, distributed under the MIT licence. The GEXF (Graph Exchange XML Format) format has now its dedicated project, independent from Gephi. It allows to use GEXF in daily needs for exchanging rich network data. It compiles both basic use cases like network topology and advanced features like dynamic and hierarchical networks.
This tool has been long-awaited by the community, to make the daily use of reading and producing GEXF files as easily and efficiently as we can. Forget the boring activity of reading the format specification, interpreting it correctly and implementing a solution to export your data to Gephi. Libgexf do this for you, and is up-to-date according to the GEXF specifications.
Though the library is written in C++ a variety of language bindings make it available in other environments. Libgexf currently only works on Linux systems (tested on Ubuntu 8.10 and 9.04), but the portability will be increased on demand. A Python binding facility is also provided, and Perl will be added soon.
You are welcome to try it and help us improving this toolkit for your benefits! A dedicated forum section has just opened.
