XML-based Exchange Formats
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.
