General Information

  • 8th International Workshop on Bidirectional Transformations
  • http://bx-community.wikidot.com/bx2019:home
  • June 4, 2019, Saint Joseph’s University, Philadelphia, PA, USA
  • as part of the Philadelphia Logic Week (PLW) 2019: https://sites.sju.edu/plw/

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 2019 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 has rotated between venues in different fields.

Bx 2019 will be a part of 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.
