Graph Exchange Language (GXL)
Description
The Graph Exchange Language (GXL) is a standard exchange format for graph based data. It is the culmination of a cooperative effort among an international group of researchers from disparate areas, including software reengineering and graph transformation.
GXL is realized as an XML-sublanguage and provides a standardized notation for exchanging instance data (graphs) including their graph structure (graph schemas). Both, instance and schema data are encoded using the same XML Document Type Definition (DTD).
GXL was ratified as a standard exchange format in reengienering at the Dagstuhl Seminar "Interoperability of Reengineering Tools" in January 2001. Since ratification of GXL, groups in reengineering, graph transformation, graph visualization, and other areas of software engineering have added support for the format in their tools.
Features
GXL originated in the merger of:
- GRAph eXchange format (GraX) for exchanging TGraphs (University Koblenz-Landau: Ebert1999GAI,Ebert2000GGE)
- Tuple Attribute Language (TA) (University of Waterloo, Canada)
- graph format of the PROGRES graph rewriting system (Darmstadt University of Technology)
Features were added to this initial graph model to handle hierarchical graphs and hypergraphs. Other ideas were taken from data formats used in reengineering and graph technology:
- ATerms
- Relation Partion Algebra
- Rigi Standard Format
- daVinci
- GML/Graphlet
- XGMML
- Graph(X)ML
- GTXL
Consequently, GXL can be be viewed as a generalization of these formats.
Fields of Application
GXL is currently used in our project GUPRO .
