Ontology as Conceptual Schema in Databasemodelling
Gustaf Svedjemo, Erland Jungert · Signal-Image Technology and Internet-Based Systems · 2006
Sweden has an enormous treasure in its vast number of large-scale historical maps from a period of 400 years. These are fre-quently used in temporal studies and different kinds of historical and archaeological research problems. A full and systematic analyse of this material from a database perspective has not been conducted. In a prior article, a conceptual analysis resulting in an ontology for the Gotlandic maps of 1693-1705 (GM1700) was presented. In this paper it is demon-strated how this ontology can be used as a conceptual schema for a logical E/R database schema. The Ontology is described in the terms of the Protege meta-model and the E/R schema in UML. The mapping be-tween the two is a set of simple rules, which are easy for a human to comprehend, but hard to automate. The E/R schema is implemented in a DBMS- and a GIS system.
