Using graph rewriting to specify software architectural transformations

H. Fahmy, R.C. Holt
2000 Proceedings ASE 2000. Fifteenth IEEE International Conference on Automated Software Engineering  
Specifically, we use the PROGRES tool to formulate executable graph-rewriting specifications for various architectural transformations in order to demonstrate the strengths of using graph rewriting.  ...  In this paper, we use graph rewriting to specify these transformations so that we can work towards automating them.  ...  The transformations, which are commonly applied to the graph models of the software architectures, can be classified into three classes [6] : Contain Use (1) Transformations for understanding.  ...

Towards a Notion of Transaction in Graph Rewriting

P. Baldan, A. Corradini, F.L. Dotti, L. Foss, F. Gadducci, L. Ribeiro
2008 Electronical Notes in Theoretical Computer Science  
We define transactional graph transformation systems (t-gtss), a mild extension of the ordinary framework for the double-pushout approach to graph transformation, which allows to model transactional activities  ...  A transaction is then a suitably defined minimal computation which starts and ends in stable states.  ...  In this paper we face, from a foundational perspective, the problem of equipping graph transformation with mechanisms for modelling transactions.  ...

Defining visual notations and their manipulation through meta-modelling and graph transformation

Juan de Lara, Hans Vangheluwe
2004 Journal of Visual Languages and Computing  
As models, meta-models and meta-meta-models can be represented as attributed, typed graphs, these operations can be expressed using graph grammars [2] .  ...  This paper presents a framework for the definition of visual notations (both syntax and semantics) based on meta-modelling and graph transformation.  ...  Acknowledgements The authors would like to thank the anonymous referees for their accurate and very useful comments.  ...

Constraint graphs as security filters for privacy assurance in medical transactions

George Mathew, Zoran Obradovic
2011 Proceedings of the 2nd ACM Conference on Bioinformatics, Computational Biology and Biomedicine - BCB '11  
We model transactions as exchange of graphs and propose constraint graphs as transaction filters for attribute-based transformations in clinical settings.  ...  Results of our experiments using constraint graphs are consistent with published benchmark results.  ...  We model graphs as the currency for transactions. Pattern graphs in GraphQL are extended to prototype graphs and forms the basis for constraint graphs.  ...

Metamodel-Based Model Transformation with Aspect-Oriented Constraints

László Lengyel, Tihamér Levendovszky, Gergely Mezei, Bertalan Forstner, Hassan Charaf
2006 Electronical Notes in Theoretical Computer Science  
A widely used approach to model transformation uses graph rewriting as the underlying transformation technique.  ...  The use of OCL as a constraint and query language in modeling is essential. We have shown that it can be applied to model transformations as well.  ...  This mathematical background makes it possible to treat models as labeled graphs and to apply graph transformation algorithms to models using graph rewriting [15] .  ...

Checking Business Process Models for Compliance – Comparing Graph Matching and Temporal Logic [chapter]

Dennis M. Riehle
2019 Lecture Notes in Business Information Processing  
Two dominant concepts in this area are graph-based pattern matching and pattern matching based on temporal logic.  ...  A key objective of BPCM is to ensure and maintain compliance of business processes models with certain regulations, e.g. governmental laws.  ...  As graph matching is able to directly operate on the process model, the pattern is directly mapped to elements of the process model using algorithms of graph matching.  ...
