Graph Modeling Language (GML) is a hierarchical ASCII-based file format for describing graphs. It has been also named Graph Meta Language.

Example

A simple graph in GML format: 

graph [ comment "This is a sample graph" directed 1 id 42 label "Hello, I am a graph" node [ id 1 label "node 1" thisIsASampleAttribute 42 ] node [ id 2 label "node 2" thisIsASampleAttribute 43 ] node [ id 3 label "node 3" thisIsASampleAttribute 44 ] edge [ source 1 target 2 label "Edge from node 1 to node 2" ] edge [ source 2 target 3 label "Edge from node 2 to node 3" ] edge [ source 3 target 1 label "Edge from node 3 to node 1" ] ]

Applications supporting GML

  • Cytoscape, an open source bioinformatics software platform for visualizing molecular interaction networks, loads and save previously-constructed interaction networks in GML.
  • Gephi, an open source graph visualization and manipulation software.
  • Graph-tool, a free Python module for manipulation and statistical analysis of graphs.
  • NetworkX, an open source Python library for studying complex graphs.
  • Social Network Visualizer (SocNetV), a free software application for social network analysis and visualization. SocNetV can load GML formatted text files.[1]
  • Tulip (software) is a free software in the domain of information visualisation capable of manipulating huge graphs (with more than 1.000.000 elements).
  • yEd, a free Java-based graph editor, supports import from and export to GML.
  • The Graphviz project includes two command-line tools (gml2gv and gv2gml) that can convert to and from the DOT file format.
  • The Graph Template Library, a C++ library for graphs and algorithms, uses GML for import and export.
  • A sample GML-parser written in C released under the LGPL.
