The GraphML project was initiated by the Graph Drawing Steering
prior to Graph Drawing
2000 in Williamsburg. A workshop
on file formats
was held on the eve of the symposium, and it was agreed on to form a
which would define a new XML-based file format which is to eventually
form a standard for the graph drawing community and its cooperators.
One of the main predecessors for GraphML is GML. GML was the
outcome of an initiative that started at Graph Drawing 1995
in Passau and ended at Graph Drawing
1996 in Berkeley. GML was (and still is) the primary file format
for Graphlet, and
is also supported by several other graph drawing systems.
GraphML Project Group
GraphML is designed by many people in many different places.
With contributions from many others, current activities are
- Ulrik Brandes (University of Konstanz)
- Markus Eiglsperger

- Jürgen Lerner (University of Konstanz)
- Christian Pich (University of Konstanz)
The GraphML advisory board consists of
- Ivan Herman (CWI)
- Stephen North (AT&T Research)
- Roberto Tamassia (Brown University)
Prior to the structural layer proposal, the following additional

- Michael Himsolt (DaimlerChrysler)
- M. Scott Marshall (then CWI)
- Vladimir Batagelj (University of Ljubljana)
- Anne-Lise Gros (LIRMM)
- Carsten Gutwenger (Caesar)

A public discussion list is to open soon.
About the GraphML Website
The GraphML website has been redesigned and relaunched on June 22,
Pages are now generated using the
Apache Software Foundation's
XML publishing framework Cocoon.
We thank Jonas Ritter (University of Konstanz) for his support.
