The enactment of blockchain-based collaborative processes typically requires a profound understanding of the process being executed, limiting support for flexible processes that cannot be fully prespecified at design time. To overcome this limitation, support for looseness, dealing with the configuration and execution of underspecified processes, is essential. In this paper, we conduct a systematic literature review to examine looseness support for blockchain-based collaborative processes from a behavioral and organizational perspective. In addition, we identify open research challenges to pave the way for further research in this area.}, keywords = {blockchain, Collaborative processes, Flexibility, Looseness}, doi = {10.1007/978-3-031-43433-4_2}, url = {https://link.springer.com/chapter/10.1007/978-3-031-43433-4_2}, author = {Tom Lichtenstein and Hassan Atwi and Mathias Weske and Cesare Pautasso} } @inproceedings {wesoa2015, title = {From Choreography Diagrams to RESTful Interactions}, year = {2015}, month = {November}, publisher = {Springer}, address = {Goa, India}, abstract = {Today, business process management is a key approach to organize work, and many companies represent their operations in business process models. Recently, choreography diagrams have been introduced to represent interactions between business processes, run by different partners. While there is considerable work on using process models during process implementation, there is little work on using choreography models to implement interactions between business processes. In this paper, a novel approach to enhance choreography diagrams by execution information is introduced. The approach is based on the REST architecture style, which is the primary way for interacting systems. Using enhanced choreography diagrams allows us to develop REST-based interactions among business partners in an efficient manner. The approach is illustrated by an example of an accommodation reservation service.}, keywords = {BPMN Choreography, RESTful conversation}, author = {Adriatik Nikaj and Sankalita Mandal and Cesare Pautasso and Mathias Weske} }
