Graph Modelling Language (GML) is a hierarchical ASCII-based file format for describing graphs. It has been also named Graph Meta Language.
Applications supporting GML
- Clairlib, a suite of open-source Perl modules intended to simplify a number of generic tasks in natural language processing (NLP), information retrieval (IR), and network analysis (NA).
- Cytoscape, an open source bioinformatics software platform for visualizing molecular interaction networks, loads and save previously-constructed interaction networks in GML.
- NetworkX, an open source Python library for studying complex graphs.
- ocamlgraph, a graph library for OCaml.
- OGDF, the Open Graph Drawing Framework, an open source C++ library containing implementations of various graph drawing algorithms. The library is self contained; optionally, additional packages like LP-solvers are required for some implementations.
- 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.
