The Resultmaker Online Consultant: From Declarative Workflow Management in Practice to LTL

We present the process model employed in the result-maker online consultant (ROC) workflow management system as an example of a declarative workflow language used in practice. We describe and formalize the key primitives of the ROC process model as linear time temporal logic (LTL) formulas, in line with a recent proposal of van der Aalst and Pesic to use LTL as the foundation for flexible declarative process languages. The work is one of the first steps in a recently initiated research project (trustcare) aiming at contributing to the foundations for workflow management for trustworthy pervasive healthcare services by combining research in formal process models, pervasive user interfaces, and development of research based prototype extensions to the ROC workflow management system.
