Bidirectional transformations (bx) are a mechanism for maintaining the consistency of at least two related sources of information. Such sources can be databases, software models, documents, graphs, and trees. BX are an emerging topic in a wide range of research areas with prominent presence at top conferences in different fields. The workshop BX'12 now establishes a dedicated venue for bx in all relevant areas. The methodologies used for bx range from classical program transformation to graph transformation techniques, from ad-hoc techniques for data synchronization to the development of domain-specific languages and their integration. We also solicit papers on model/metamodel co-evolution, which is a different yet closely related subject.

Aims and Topics

The aim of the workshop is to bring together researchers, established and new, interested in bidirectional transformations from different perspectives, such as: language-based approaches, software/model transformations, and data/schema co-evolution.

Topics of interest for BX'12 include, but are not limited to:

• (coupled) software/model transformations
• software-model synchronization
• data-schema co-evolution and data synchronization
• consistency analysis
• language-based approaches
• analysis/classification of requirements for bx technologies
• case studies and tool support
• comparison of bx technologies
• efficiency of algorithms and benchmarks

Regular submissions (11-15 pages) can be:

• research papers providing new concepts and results
• position papers and research perspectives
• papers that apply bx in new domains
• papers closing gaps between formal concepts and application scenarios

We also welcome submissions of short papers as well as abstracts for lightning talks.
