“…Choreography fragments are one possibility to refine only partially specified choreographies during run time. For example, abstract constructs [8] could be replaced with choreography logic provided by choreography fragments. In order to support multi-tenancy scenarios [20], we plan to investigate how tenants and users can register choreography fragments to configure a template choreography model according to their requirements.…”

“…Choreography fragments can be used to capture best practices and recurring patterns in choreography models, store them in an appropriate library, and insert them into new choreography models. Choreography fragments can also be used for the refinement of partially defined choreography models containing abstract constructs, like the ones introduced in [8], to concrete choreography models. Similar to process fragments, choreography fragments can be created in either a top-down or bottom-up manner.…”

“…Choreography synthesis and service adaption have been studied in literature such as [33][34][35][36][37][38][39], and automatic synthesizing platforms are also under development such as the CHOReVOLUTION platform. We focus in this paper on the system architecture of AEMS and the utilization of choreographies to coordinate multistakeholder services for emergency management.…”

Emergency management has long been recognized as a social challenge due to the criticality of the response time. In emergency situations such as severe traffic accidents, minimizing the response time, which requires close collaborations between all stakeholders involved and distributed intelligence support, leads to greater survival chance of the injured. However, the current response system is far from efficient, despite the rapid development of information and communication technologies. This paper presents an automated collaboration framework for emergency management that coordinates all stakeholders within the emergency response system and fully automates the rescue process. Applying the concept of multiaccess edge computing architecture, as well as choreography of the service oriented architecture, the system allows seamless coordination between multiple organizations in a distributed way through standard web services. A service choreography is designed to globally model the emergency management process from the time an accident occurs until the rescue is finished. The choreography can be synthesized to generate detailed specification on peer-to-peer interaction logic, and then the specification can be enacted and deployed on cloud infrastructures.

Microservice compositions based on the choreography of BPMN fragments: facing evolution issues

Business Processes (BPs) are commonly used by organizations to describe their goals. However, the existent decentralization found in many organizations forces them to build such BPs by coordinating distributed and fragmented BPs. Within this context, microservices arise as a very interesting and convenient way to address the implementation of such processes due to their low coupling characteristic. In this case, the coordination of such fragmented BPs is usually achieved by means of event-based choreographies. One of the main challenges to be faced by choreographies is their evolution due to the complexity that introduces the need of integrating changes among autonomous and independent partners. We face the challenge of evolving a microservice composition that is globally defined in a BPMN model but executed through a choreography of BPMN fragments. We introduce a protocol to manage the propagation of a change done by one microservice to be integrated into both the BPMN fragments of the rest of the microservices and the global BPMN model. This protocol also supports the negotiation among participants and the automatic suggestion of model adaptations to maintain the functional integrity of the composition. These suggestions are supported by a catalogue of adaptation rules that precisely characterize every possible change and propose actions to be considered by the affected microservices. All the evolution process is done at the modelling level, without managing hard-coded implementations. We have developed specific tools to facilitate the practical adoption of this protocol, and we have validated our work in an experiment with users. We can conclude that the proposed approach is effective to evolve microservice compositions implemented as event-based choreography of BPMN fragments from the local perspective of one partner.
