Fourth International Workshop on Bidirectional Transformations (Bx 2015)

L'Aquila, Italy
Friday, July 24, 2015 (co-located with STAF'15 July 20-24, 2015)

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 (namely databases, programming languages, software engineering, and graph transformation), but with results in one field often getting limited exposure in the others. Bx 2015 is a dedicated venue for Bx in all relevant fields, and is part of a workshop series that was created in order to promote cross-disciplinary research and awareness in the area. As such, since its beginning in 2012, the workshop rotated between venues in different fields. In 2015, Bx is co-located with STAF for the first time.

Aim and topics

The aim of the workshop is to bring together researchers and practitioners, established and new, interested in Bx from different perspectives, such as:

  • 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

Paper categories

Submissions to Bx 2015 can be:

  • Regular papers (up to 15 pages)
    • in-depth presentations of novel concepts and results
    • applications of Bx to new domains
    • survey papers providing novel comparisons between existing technologies
    • case studies
  • Short papers (up to 8 pages)
    • work in progress
    • small focused contributions
    • position papers and research perspectives
  • Tool papers (up to 8 pages)
    • presentation of new tools or substantial improvements to existing ones
  • Benchmark papers (up to 8 pages)
    • new benchmark proposals, focusing on assessing aspects of Bx not covered by the examples currently available at the Bx example repository

Proceedings and special issue

The workshop proceedings, including all accepted papers, will be published electronically by CEUR ( Authors of accepted papers (of all categories) that have high-quality and the potential to be extended into journal articles will be invited to submit a revised and extended version of their paper to a special issue of the Journal of Object Technology (; these papers will then be subject to a careful reviewing and selection process according to the scientific standards of the Journal of Object Technology.
