The Environmental Data Exchange Network for Inland Water (EDEN-IW) project's main aim is to develop a system for making disparate and heterogeneous databases of Inland Water quality more accessible to users. The core technology is based upon a combination of: ontological model to represent a Semantic Web based data model for IW; software agents as an infrastructure to share and reason about the IW se-mantic data model and XML to make the information accessible to Web portals and mainstream Web services. This presentation focuses on the Semantic Web or Onto-logical model. Currently, we have successfully demonstrated the use of our systems to semantically integrate two main database resources from IOW and NERI - these are available on-line. We are in the process of adding further databases and sup-porting a wider variety of user queries such as Decision Support System queries.
