Recently, a variety of workflow patterns has been proposed focusing on specific aspects like control flow, data flow, and resource assignments. Though these patterns are relevant for implementing Business Process Model-ing (BPM) tools and for evaluating the expressiveness of BPM languages, they do not contribute to reduce redundant specifications of(More)
For its reuse advantages, workflow patterns (e.g., control flow patterns, data patterns, resource patterns) are increasingly attracting the interest of both researchers and vendors. Frequently, business process or workflow models can be assembeled out of a set of recurrent process fragments (or recurrent business functions), each of them having generic(More)
Virtual Organizations (VO) have emerged as a new type of inter-organizational relationship for dealing with emerging challenges. The information system support for a VO poses new challenges to system design. Recent works define three levels of abstraction, namely an intentional level, an organizational level, and an operational level. For such a staged(More)
For their reuse advantages, workflow patterns are increasingly attracting the interest of both researchers and vendors. However, actual workflow modeling tools do not provide functionalities that enable users to define , query, and reuse workflow patterns properly. In this paper we gather a set of requirements for process modeling tools that aim to support(More)
Research on workflow activity patterns recently emerged in order to increase the reuse of recurring business functions (e.g., notification, approval, and decision). One important aspect is to identify pattern co-occurrences and to utilize respective information for creating modeling recommendations regarding the most suited activity patterns to be combined(More)
Several approaches have already been proposed to extract both business processes and business rules from a legacy source code. These approaches consider static source code analysis for the extraction procedure. However, business processes have components that can not be directly extracted by static analysis (i.e., participants, responsibilities, and(More)
Workflow activity patterns represent a set of recurrent behaviours that can be found in a wide range of business processes. In this paper we address the problem of determining the presence of these patterns in process models. This is usually done manually by the analyst, who inspects the model and interprets its elements in terms of the semantics of those(More)
Due to their high level of abstraction and their reusability, workflow patterns are increasingly attracting the interest of both BPM researchers and BPM tool vendors. Frequently, process models can be assembled out of a set of recurrent business functions (e.g., task execution request, approval, notification), each of them having generic semantics that can(More)
