We describe the programming system for the graph-transformation language GP, focusing on the implementation of its compiler and abstract machine. We also compare the system’s performance with other graph-transformation systems. The GP language is based on conditional rule schemata and comes with a simple formal semantics which maps input graphs to sets of output graphs. The implementation faith...

Automated model transformations play an important role in modern model-driven system engineering in order to query, derive and manipulate large, industrial models. Since such transformations are frequently integrated to design environments, they need to provide short reaction time to support software engineers. Graph transformation (GT) [1] based tools have been frequently used for specifying a...

Transactional graph transformation systems (t-gtss) have been recently proposed as a mild extension of the standard dpo approach to graph transformation, equipping it with a suitable notion of atomic execution for computations. A typing mechanism induces a distinction between stable and unstable items, and a transaction is defined as a shift-equivalence class of computations such that the start...

The development of common exchange formats for graphs and graph transformation systems is an ongoing initiative within the EU Working Group APPLIGRAPH (Applications of Graph Transformation). The author is reporting on the current state of this format discussion. The formats are based on the extensible markup language XML developed to interchange documents of arbitrary types. Graphs are basic st...

Highly configurable metamodeling environments and graph transformation techniques have been applied successfully in software system modeling and other areas. In this paper a uniform treatment of these two methods is illustrated by a tool called Visual Modeling and Transformation System. The concepts of an n-layer metamodeling environment is outlined with the related topological and attribute is...
