Third International Workshop on Bidirectional Transformations (BX 2014) *Deadline extended due to many requests. Original deadline became abstract deadline.* Friday March 28th, 2014 Athens, Greece co-located with EDBT/ICDT 2014 Web site: http://bx-community.wikidot.com/bx2014:home Submission site: https://www.easychair.org/account/signin.cgi?conf=bx2014 Paper length: 3-8 pages, ACM format. In-progress work is highly encouraged, if limited to 4 pages. Bidirectional transformations (bx) are a mechanism for maintaining the consistency of at least two related sources of information. Such sources can be relational data, software models, documents, graphs, trees, and so on. BX are an emerging topic in a wide range of research areas with prominent presence at top conferences in different fields. However, much of the research in bx tends to get limited exposure outside of a single field of study. The purpose of this workshop series is not only to further research into bx, but to promote cross-disciplinary research and awareness in the area. The first two instances of this workshop, BX'12 and BX'13, served as a dedicated venue for bx in all relevant areas, including: - Databases - Programming Languages - Software Engineering - Graph Transformation This instance of the workshop is the first at a database venue. The workshop rotates between venues in different areas to promote the cross-disciplinary nature of the work, as methodologies used for bx range from classical program transformation and updateable views 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 and practitioners, established and new, interested in bidirectional transformations from different perspectives, such as: * inversion of data exchange mappings * new perspectives on view updatability * data-schema co-evolution and data synchronization * software-model synchronization * consistency analysis * (coupled) software/model transformations * language-based approaches Submissions can be: * novel research concepts and results * position papers and research perspectives * application of bx in new domains * analysis of gaps between formal concepts and application scenarios * examination of the efficiency of algorithms * analysis/classification of requirements for bx technologies * proposals and justification for benchmarks * summary papers providing novel comparisons between existing technologies * case studies and tool support Submitted papers must be in ACM format in accordance with the other workshops and proceedings at EDBT/ICDT. Papers may be 3-8 pages in length; the length of the paper should be appropriate for the level of completeness of the work. Important Dates: Abstract submission date: 7th December 2013 Paper submission date: 13th December 2013 Author notification: 7th January 2014 Camera-ready date: 20th January 2014 Workshop date: 28th March 2014 Accepted papers will be published in the workshop proceedings of EDBT/ICDT and will be available at the conference.
