Abstract

To address problem of modeling service choreographies, the paper tackles the following challenges of the state of the art in choreography modeling: i) choreography models are not well-connected with the underlying business vocabulary models. ii) there is limited support for decoupling parts of business logic from complete choreography models. This reduces dynamic changes of choreographies; iii) choreography models contain redundant elements of shared business logic, which might lead to an inconsistent implementation and incompatible behavior. Our proposal --- rBPMN --- is an extension of a business process modeling language with rule and choreography modeling support. rBPMN is defined by weaving the metamodels of the Business Process Modeling Notation (BPMN) and REWERSE Rule Markup Language (R2ML).
