Preface for the special issue on tool papers of the 21st International Conference on Coordination Models and Languages, COORDINATION 2019

摘要

This special issue reports on selected tool papers of the 21st International Conference on Coordination Models and Languages (COORDINATION 2019), held in Copenhagen, Denmark, on June 17-21, 2019. For the first time, the conference welcomed submissions describing technological artefacts, including innovative prototypes, for modelling, analysing, simulating or testing systems in the scope of the research topics of COORDINATION. Submissions included both a short abstract describing the tool and a short video that showcased the presentation to be carried out at the conference, an innovative feature that was highly appreciated by the members of the program committee. There was a total of seven submissions to the tool track (about one third of the total submissions), and five were accepted for publication (also about one third of the total) as full papers extending the submitted version. The authors of the more mature contributions, taking also tool usability into account, were invited to submit to this special issue. A total of four invitations were issued, and all four contributions are included in this special issue. Each submission was reviewed by three experts, one of which chosen from the COORDINATION PC members who reviewed the conference version, and the remaining two among recognised experts in the specific area of the submission, including authors of other contributions and other COORDINATION PC members.
