Standards and semantics to support interoperable software solutions in the water distribution chain

The goal of the EU-FP7 project WatERP is more interoperability of software systems along the water-supply chain. Having a better data exchange between different stakeholders along the supply chain shall enable more intelligent decision-support for saving water and energy. In order to achieve that higher degree of interoperability, the WatERP project develops a flexible and extensible communication architecture for the different kinds of tools in use, based on a Service-Oriented Architecture (SOA) which is complemented by a Multi-Agent System (MAS) for service identification and orchestration. One central element of the software architecture is the WatERP Water Data Ware-house which acts as a central data hub between different software systems. Both the SOA-MAS architecture and the WDW are based to the most reasonable extent on OGC´s open standards for geospatial data processing and are carefully extended by semantic technologies. In this paper, we sketch the SOA-MAS architecture and explain some details of the WDW.
