The reference model for the marine spatial data infrastructure of Germany (MDI-DE) is the guideline for all developments inside this infrastructure and is based on the Reference Model for Open Distributed Processing (RM-ODP) and other reference models for federal states and Germany as a whole. The reference model is composed of several submodels which focus on different aspects of the marine data infrastructure. Because the undertaking is embedded in a series of regulations and developments this paper proposes two approaches on modelling scenarios for the Marine Strategy Framework Directive (MSFD) and the Water Framework Directive (WFD) using the Unified Modelling Language (UML).Text/Conference Paper
