Information Preserving Bidirectional Model Transformations [chapter]

Hartmut Ehrig, Karsten Ehrig, Claudia Ermel, Frank Hermann, Gabriele Taentzer
Fundamental Approaches to Software Engineering  
But up to now, there is no formal result showing under which condition corresponding forward and backward transformations are inverse to each other in the sense of information preservation.  ...  Most of these transformations need to be bidirectional to e.g. report analysis results, or keep coherence between models.  ...  We will use it in this paper to illustrate the triple graph grammar approach and especially, the conditions for information preserving bidirectional transformations.  ...

Synchronizing concurrent model updates based on bidirectional transformation

Yingfei Xiong, Hui Song, Zhenjiang Hu, Masato Takeichi
2011 Journal of Software and Systems Modeling  
A bidirectional model transformation keeps two models consistent by updating one model in accordance with the other. However, it does not work when the two models are modified at the same time.  ...  We then propose a new algorithm to wrap any bidirectional transformation into a synchronizer with the help of model difference approaches.  ...  Instead of transforming models, incremental bidirectional transformation transforms an update on one model to an update on the other model.  ...

Feature-based classification of bidirectional transformation approaches

Soichiro Hidaka, Massimo Tisi, Jordi Cabot, Zhenjiang Hu
2015 Journal of Software and Systems Modeling  
Then the feature model is used to highlight some unexplored research lines in bidirectional transformations.  ...  Bidirectional model transformation is a key technology in Model-Driven Engineering (MDE), when two models that can change over time have to be kept constantly consistent with each other.  ...  Conversely, information-preserving TGG [40] , a restriction of the TGG language to information-preserving transformation, is an example of approach that sacrifices Turing-completeness.  ...

Supporting Parallel Updates with Bidirectional Model Transformations [chapter]

Yingfei Xiong, Hui Song, Zhenjiang Hu, Masato Takeichi
2009 Lecture Notes in Computer Science  
A bidirectional model transformation keeps two models consistent by updating one model in accordance with the other. However, it does not work when the two models are modified at the same time.  ...  In this paper we propose a new algorithm that wraps any bidirectional transformation into a synchronizer with the help of a model difference approach.  ...  We plan to design a resolution procedure based on a specific transformation language and a specific model difference approach.  ...

Confidentiality in the process of (model-driven) software development

Michael Johnson, Perdita Stevens
2018 Conference Companion of the 2nd International Conference on Art, Science, and Engineering of Programming - Programming'18 Companion  
In model-driven development confidentiality issues become particularly clear and tractable, and bidirectional transformations have a key technical role.  ...  When necessary, the models are reconciled by bidirectional transformations, which automate a process which would otherwise have to be undertaken manually by the groups of experts meeting and studying both  ...  We have been discussing the symmetric case of a bidirectional transformation, that in which each model contains information not captured in the other, and therefore, in which consistency restoration in  ...

JTL: A Bidirectional and Change Propagating Transformation Language [chapter]

Antonio Cicchetti, Davide Di Ruscio, Romina Eramo, Alfonso Pierantonio
2011 Lecture Notes in Computer Science  
In Model Driven Engineering bidirectional transformations are considered a core ingredient for managing both the consistency and synchronization of two or more related models.  ...  In this paper, the Janus Transformation Language (JTL) is presented, a bidirectional model transformation language specifically designed to support nonbijective transformations and change propagation.  ...  In the context of bidirectional transformation it should coexist with the ability to propagate changes in both the directions but preserves information in the models and, in our case, also allows the approximation  ...
