Abstract

This paper presents the result of recent work on the use of geospatial repositories to store the conceptual content of object oriented application database schemas and dictionaries aligned with international standards in geographic information (ISO/TC 211 and OGC). According to software engineering and database concepts, a geospatial repository can be defined as a collection of (meta) data structured in a manner to provide information about the semantics, geometry, temporality, and the integrity constraint of data stored in a geospatial database. For the last 6 years, ISO/TC 211 and OGC have been developing standards about geographic information to enable access and interoperability of geographic information; parts of these standards impact directly on geospatial repositories. Our work demonstrates that it is possible to develop a geospatial repository aligned with these standards and to implement it in a UML-based visual modelling tool.
