An object repository model for the storage of spatial metadata

Abstract

The design of spatial information systems has traditionally been carried out independently of mainstream database developments. It is contended that the adoption of mainstream database design techniques is important to progress in the spatial information systems development field. An accepted approach to the development of information systems is through an integrated development environment with a design repository at its core. This paper proposes a skeleton model for the design of a repository to store spatial metadata. An object oriented modelling approach is adopted in preference to an entity relationship approach because of its ability to model functional and dynamic aspects of the repository.
