Abstract:The Formalized Process Description (FPD) according to VDI/VDE 3682 provides a standardized graphical notation for describing processes across engineering domains but lacks a standardized, tool-independent data format for machine-readable model exchange. This paper presents an AutomationML (AML) domain library that formalizes the complete set of FPD language elements, their attributes, connection semantics, and graphical representation information as class libraries based on the Computer Aided Engineering Exchange (CAEX) 3.0 metamodel. The library comprises five interrelated parts: a RoleClassLib defining the semantic roles, an InterfaceClassLib for connection types, two AttributeTypeLibs for the information model and diagram interchange, and a SystemUnitClassLib providing instantiation templates. Key design decisions regarding inheritance, diagram structure, hierarchical decomposition, and the representation of graphical information are discussed along with the alternatives that were considered. A bidirectional mapping tool demonstrates the library's applicability by converting between a web-based FPD modeler and AML.
