Abstract
Modern Business Process Management systems have to work effectively in a distributed cloud environment and to adapt quickly to dynamic changes. One of the key approaches to increase business process adaptability is to make process definitions more flexible. Usually, this requires to express complex constraints and conditions within a process definition. These complex elements are related to the history of process execution, current organizational and application data. In addition, such complex constraints and conditions should be represented in a standardized and yet simple way. In order to satisfy the above requirements, we need: (1) a business process metamodel that includes proper data structures for process definitions and the history of their execution; (2) a powerful and easy to understand language to query models instantiated from the metamodel; (3) integration of that query language with a widely used business process definition language. In this chapter, we propose Business Process Query Language (BPQL) together with the Business Process Metamodel. BPQL is integrated with the Business Process Model and Notation language increasing significantly its expressiveness and flexibility. We also present results of applying BPQL in the OfficeObjects® WorkFlow system.
