Chatting Roles: A Pragmatic Service Resolution Infrastructure for Service Choreography based on Publish/Subscribe

Abstract In the following a minimalistic approach for process interoperability, consisting of a topic-based Publish/Subscribe system is presented. It combines an infrastructure and a method guiding the implementation of a basic Service Resolution Infrastructure (SRI) for Service Choreography and Service Interoperability. This SRI can be used to realize resilient collaboration tasks in Industry 4.0 (I4) and Industrial Internet of Things (IIoT) settings without central coordination.
