The 2023 Transformation Tool Contest (TTC) seeks your own spins of four interesting model transformation problems. The deadline for solution descriptions is 29th June 2023, immediately followed by a round of open peer reviewing. As in previous editions, solution descriptions will be published in a post-proceedings volume, and lead to continued collaboration for producing a per-case journal article.
The aim of this event is to compare the expressiveness, the usability and the performance of graph, model and program transformation tools along a number of selected case studies. A deeper understanding of the relative merits of different tool features will help to further improve transformation tools and to indicate open problems.
This contest is the fifteenth of its kind (after an AGTiVE 2007 session, as GraBaTs 2008 and 2009 contests, and the TTC 2010, 2011, 2013--2021 contests). For the eighth time, the contest is co-located with several leading software engineering conferences as part of the Software Technologies: Applications and Foundations (STAF) federation. Teams from the major international research groups in the development and use of transformation tools are expected to participate in the TTC again.
The following case studies have been selected:
The case description, supporting resources, and discussion between solution developers are hosted at the source code repositories linked to above.
If you would like to participate in the contest, you are now asked to take your favourite transformation tool and submit your solutions. A submission should consist of a paper and the actual solution (i.e., programs, models, etc.). The paper should include a description of the chosen case study variant (if any) and a presentation of the chosen solution, including a discussion of design decisions. Examples can be explored at the TTC 2021 website.
Solutions should be submitted via Easychair by 29th June 2023. Before the same deadline, each case study solution (tool, project files, documentation) should be made available for review and demonstration via a public version control repository (e.g. on Github or Bitbucket). Docker Hub images would be highly appreciated as well.
Immediately after the submission deadline, please note solution developers will be asked to participate in a round of open review of other solutions. Therefore, we ask that all solution developers are available in the period 29th June to 13th July 2023 to participate in these discussions.
Besides the presentations of the submitted solutions, we will have an online event where solution authors will be asked to present their solutions in front of a bigger audience and answer any questions afterwards. The date of this event will be defined together with solution authors.
For TTC 2023 there will be several publication opportunities:
