Bidirectional transformations (BX) serve to maintain consistency between different representations of related and often overlapping information, translating changes in one representation to the others. We present a brief introduction to the field, in order to provide some common background to the remainder of this volume, which constitutes the lecture notes from the Summer School on Bidirectional Transformations, held in Oxford in July 2016 as one of the closing activities of the UK EPSRC…

- Computer Science
- 2020

This thesis reconciles the compactness of ASTs and printing quality by proposing retentive printing, which takes not only an AST but also a piece of original program text, so that there is no need to enrich ASTs with unnecessary information.

### Applying Bidirectional Transformations to the Design of Interoperable EMR Systems

- Computer ScienceJ. Heal. Informatics Res.

### Comprehensive Systems: A formal foundation for Multi-Model Consistency Management

- Computer ScienceFormal Aspects of Computing

This paper proposes and investigates a novel comprehensive system construction, which is able to represent multi-ary relations among multiple models in an integrated manner and thus serves as a formal foundation for artefacts used in consistency management activities involving multiple models.

- Computer ScienceDagstuhl Reports
- 2011

The Dagstuhl Seminar 11031 aimed at providing a place for working together to define a common vocabulary of terms and desirable properties of bidirectional transformations, develop a suite of benchmarks, solve some challenging problems, and launch joint efforts to form a living bx community of cooperating experts across the identified subdisciplines.

- Computer ScienceA List of Successes That Can Change the World
- 2016

This paper reviews the proposals for monadic lenses to date, and offers some improved definitions, paying particular attention to the obstacles to naively adding monadic effects to existing definitions of pure bx such as lenses and symmetric lenses, and the subtleties of equivalence of symmetric bidirectional transformations in the presence of effects.

### JTL: A Bidirectional and Change Propagating Transformation Language
