A central element to achieve that is the WatERP Water Data Warehouse which shall act as a central data-exchange platform between different software systems. The WDW shall be able to store and provide sensor, measurement and forecasting data, as well as semantic knowledge about the water-supply chain. It shall be as standards-compliant as reasonable and shall offer query and reasoning facilities over sensor data, spatial information and ontological knowledge. In this paper, we show the basic architecture of the WDW and shortly discuss its main design decisions.Text/Conference Paper
