File-format for graphs which consists of a language core to describe the structural properties of a graph and a flexible extension mechanism to add application-specific data

GraphML is a comprehensive and easy-to-use 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,
  • application-specific attribute data, and
  • light-weight parsers.
