We started the libgexf project a few months ago to help people creating, reading and writing efficiently GEXF files. Today we announce the second alpha release of this dynamic library, which brings new file validation (RelaxNG and XML-schema based) and data integrity checking (see examples)! These features provide a quick way to find and correct some mistakes or missing elements in your files. GEXF files created are also now compatible with Gephi 0.6 by using the Legacy writer. See the complete changelog here for more details.
Finally, New bindings are available for Perl5 and Java6, which increase the number of language bindings to 3 with the existing one in Python. Don’t hesitate to give us feedbacks and requests features.
