REST-Enabled Decision Making in Business Process Choreographies

摘要

In the field of business process management, the interaction between business actors or services are modeled via business process choreographies. However, enforcing or implementing business process choreographies is a challenge particularly related to the choreography's exclusive gateways, which are used to model shared decisions among business actors. Since there is no central locus of control, participants may interpret the data relevant for decision making differently. To tackle this problem, this paper offers a solution by delegating the decision making to a decision service. This service is based on the recently published Decision Model and Notation standard and is provided to the choreography participants via a REST interface. The RESTful decision service assures a correct implementation of choreographies' exclusive gateways and provides a blueprint for RESTful services that offer decision-making solutions based on the DMN standard.
