GraphML - graph markup language

GraphML is an XML-based file format for graphs. It consists of a language core to describe the structural properties of a graph and a flexible extension mechanism to add application specific data. Its main features include support of

  • directed, undirected, and mixed graphs,
  • hypergraphs,
  • hierarchical graphs,
  • graphical representations,
  • references to external data, and
  • user defined attribute data.
    •

    Work on GraphML was initiated in a workshop during the 2000 Graph Drawing Symposium, and a first proposal is expected to be out by the 2001 Graph Drawing Symposium.
