MurMur: Database management of multiple representations

Abstract

Successful information management implies the ability to design accurate representations of the real world of interest to targeted applications. Current systems do not provide representation schemes supporting the diversity of user needs. In the context of interoperability, as in Web access to heterogeneous data sources, they can-not properly integrate the diversity of stored representa-tions. The objective of the European project described in this paper, MurMur1, is to enhance GIS (or DBMS) functionality so that, relying on more flexible represen-tation schemes, users may easily manage information using multiple representations. The added functionality will support multiple coexisting representations of the same real-word phenomena (semantic flexibility), in-cluding representations of geographic data at multiple resolutions (cartographic flexibility). This will in par-ticular make possible a semantically meaningful man-agement of multi-scale, integrated, and temporal geo-databases.
