From Code to Product, from Myth to Reality, the CHOReVOLUTION project is achieving its goal by delivering a dynamic platform, during its third and last year. More precisely, the CHOReVOLUTION Studio for Eclipse is addressing scalable IoT/IoS applications based on choreography modelling, synthesis, adaptation, service bus, security, and cloud. It aims at integrating as much as possible existing web services to create new innovative solutions. The first applications developed for evaluating the solution provided useful feedbacks allowing us to improve the solution in order to reach a first level of maturity. The CHOReVOLUTION software are published under an open source licence and made publicly available through the OW2 community.

Step 1. Software producers cooperate
with domain experts and business
managers to
• set the business goal (for exam-
ple, assist travellers from arrival,
to staying, to departure),
• identify the tasks and partici-
pants required to achieve the
constructs and quality-of-service
constraints. In particular, CHOReOS
uses both the Q4BPMN notation—
an extension to BPMN2—to specify
nonfunctional properties and dedi-
cated automated tools to assess the
choreography specification’s quality.
