Kurzfassung
In this paper an extension to activity diagrams from the Unified Modeling Language (UML) is proposed that supports the definition of several kinds of location constraints. A location constraint is a statement that says whether it is allowed to perform an activity within a mobile workflow at a particular location or not. They therefore constitute a special case of access control that is location-aware. We cover location constraints that are assigned at the design time of the workflow schema as well as constraints that a derived during the runtime of a workflow instance. Location constraints can help to tackle mobile-specific challenges that come along with the employment of mobile workflow systems, namely security issues and usability problems
