Eighth International Workshop on Bidirectional Transformations (Bx 2019)
  • June 4, 2019, Saint Joseph’s University, Philadelphia, PA, USA

See the list of accepted papers and talks for the abstracts, papers, and slides (if available).

Bidirectional transformations (bx) are a mechanism for maintaining the consistency of at least two related sources of information. Such sources can be relational databases, software models and code, or any other document following standard or ad hoc formats. Bx are an emerging topic in a wide range of research areas, with prominent presence at top conferences in several different fields including databases, programming languages, software engineering, and graph transformation, but with results in one field often getting limited exposure in the others. The Bx workshop series was created in order to promote cross-disciplinary research and awareness in the area. As such, since its beginning in 2012, the workshop has rotated between venues in different fields.

Bx 2019 will be a part of the Philadelphia Logic Week (PLW) 2019, which also includes conference and workshops on logic, provenance, and databases, topics that we hope will complement Bx and help build engagement with these communities.

Invited Talk

  • Title: Mappings, Updates, and Provenance

Aim and Topics

The aim of the workshop is to bring together researchers and practitioners, established and new, interested in bx from different perspectives, including but not limited to:

  • bidirectional programming languages and frameworks
  • data and model synchronization
  • view updating
  • inter-model consistency analysis and repair
  • data/schema (or model/metamodel) co-evolution
  • coupled software/model transformations
  • inversion of transformations and data exchange mappings
  • domain-specific languages for bx
  • analysis and classification of requirements for bx
  • bridging the gap between formal concepts and application scenarios
  • analysis of efficiency of transformation algorithms and benchmarks
  • survey and comparison of bx technologies
  • case studies and tool support


The workshop proceedings, which include all accepted papers (except talk proposals), are published as Volume 2355 on CEUR-WS.org.
