Abstract

Information mediation is an approach used to resolve heterogeneity of online information sources. This article discusses the concept of information mediation and several related research projects that use a typical mediation model. The problems and issues with existing approaches are discussed. This article then proposes the use of metamodels as an advanced architecture for information mediation, where XML is a main driving force. The new architecture is partly established on the common warehouse metamodel (CWM), a standard adopted by the Object Management Group (OMG). Illustrative examples are presented in the article to describe and discuss the new architecture.
