Abstract
This paper presents a new approach to forming a foundation of the ISO 19115 metadata automation. The proposed approach is based on an integrated data model to store spatial metadata along with its related dataset which enables the metadata to be updated automatically and concurrently with any change in the dataset. The paper proposes an architecture for implementing this new approach based on a PostgreSQL/PostGIS database, deegree WFS-T server, and GML Application Schema as well as a graphical user interface. This approach allows the users to generate the metadata elements in parallel with the spatial dataset lifecycle (data collection, dataset creation, storage, publishing, discovery, access and retrieval, utilisation, maintenance, and planning and policy making) in an automated fashion where feasible. This has the potential to overcome the issues raised by the current metadata generation and updating approach which is rooted in a single source (ready-to-use dataset), a detached data model for storing spatial datasets and metadata, and most importantly the knowledge of the metadata author about the dataset.
