Integrating Semantic Search for Relational Data into Environmental Information Systems

In this paper we briefly discuss two system prototypes that have been developed to improve search for environmental information through semantic technologies. While the HIPPOLYTOS prototype extends a specific, commercial data warehousing and spatial reporting system - disy CADENZA - in order to make search for structured, relational data easier, the SUI system implements a semantics-enabled search-broker approach for simultaneously accessing manifold different target information systems in a comprehensive environmental information portal. Finally, we sketch the envisioned integration of HIPPOLYTOS as one such SUI target system.
