Towards Local Confluence Analysis for Amalgamated Graph Transformation
نویسندگان
چکیده
Amalgamated graph transformation allows to define schemes of rules coinciding in common core activities and differing over additional parallel independent activities. Consequently, a rule scheme is specified by a kernel rule and a set of extending multi-rules forming an interaction scheme. Amalgamated transformations have been increasingly used in various modeling contexts. Critical Pair Analysis (CPA) can be used to show local confluence of graph transformation systems. It is an open challenge to lift the CPA to amalgamated graph transformation systems, especially since infinite many pairs of amalgamated rules occur in general. As a first step towards an efficient local confluence analysis of amalgamated graph transformation systems, we show that the analysis of a finite set of critical pairs suffices to prove local confluence.

An Algorithm for the Critical Pair Analysis of Amalgamated Graph Transformations
Graph transformation has been shown to be well suited as formal foundation for model transformations. While simple model changes may be specified by simple transformation rules, this is usually not sufficient for more complex changes. In these situations, the concept of amalgamated transformation has been increasingly often used to model for each loops of rule applications which coincide in com...

It offers several analysis techniques for graph transformation systems including graph parsing, consistency checking of graphs as well as conflict and dependen...
متن کاملEfficient Detection of Conflicts in Graph-based Model Transformation
Using graph transformation as a formalism to specify model transformation, termination and confluence of the graph transformation system are required properties. Only under these two conditions, existence and uniqueness of the outcoming model is ensured. Verifying confluence of a graph transformation system is equivalent to checking both local confluence and termination. A graph transformation ...
متن کاملConfluence of Typed Attributed Graph Transformation Systems
The issue of confluence is of major importance for the successful application of attributed graph transformation, such as automated translation of UML models into semantic domains. Whereas termination is undecidable in general and must be established by carefully designing the rules, local confluence can be shown for term rewriting and graph rewriting using the concept of critical pairs. In thi...

Model transformation is one of the key activities in model-driven software development. An increasingly popular technology to define modeling languages is provided by the Eclipse Modeling Framework (EMF). Several EMF model transformation approaches have been developed, focusing on different transformation aspects. For the analysis of model transformations, graph transformation techniques provid...
