_In order to shield the modeler from the complexity of features like higher-order, static typing, and generics we provide a preconfiguration feature. Nearly everything (except the control-flow of a process) can be configured, including names, generics, types, context variables, the data-flow and documentation. This offers to create new activity libraries, just via configuring existing ones.

The configuration layer is realized via configuration graphs, SLGs (Service Logic Graphs) without any control-flow information, declaring activities with (partially) preconfigured data-flow and further meta-information denoted by preconfigured activity (cf. Fig. 1). A modeler may
