An Open-Source Modeling Editor for Declarative Process Models

This paper presents an open-source modeling environment for Declarative Process Models. Traditionally, process models have described rigid structures, where re-work, process variants, and alternatives are difficult to represent. The Dynamic Condition Response (DCR) Graphs notation is a declarative process modeling notation that enables the description of processes with a high level of flexibility, using behavioral constraints to allow only compliant executions. The DCR-js editor is an open-source web-based editor for DCR graphs for academic use that enables the process management community to interact with declarative process models. As part of the innovations of the tool, DCR-js provides an alternative, semantic-transparent representation of declarative process models. Its web-based interface makes it ideal to be used as a component in tool-based experiments on cognitive aspects of modeling business processes. With DCR-js, we expect to render declarative process models more accessible to novice and academic users.
