for Graphs and Graph Transformation Systems

On one of the last workshops on graph transformation (GRATRA2000) held as a satellite event of ETAPS2000 in March in Berlin, we had a discussion on the perspectives of graph transformation. One topic of this discussion were common exchange formats for graphs and graph transformation based on XML. Having such common formats the exchange of graphs, rules and/or whole graph transformation systems between different graph transformation-based tools on one hand, and further graph-based tools, e.g. graph drawing tools and graph databases, on the other hand, would become easier.

This initiative is settled in APPLIGRAPH , an EU Working Group on "Application of Graph Transformation". Although being started within the graph transformation and reengineering communities, this initiative is open for everybody interested in this subject.

  1. Paderborn: September 5 - 6, 2000     5 proposals and a first common model for graphs and graph transformation systems
  2. Bremen: March 1 - 2, 2001    Consolidation of core formats for graphs and graph transformation systems
  3. Erlangen: March 7 - 8, 2002     Discussion of storing hierarchical graphs in GXL and collection of open problems of GTXL
  4. Barcelona: October 8, 2002        Discussion of experiences and open problems of GXL and GTXL

A summary of this format discussion  has been presented at UNIGRA, a satellite workshop of ETAPS'01 in Genova at the end of March, 2001.
