A model-driven approach to management of integrated metadata-spatial data in the context of spatial data infrastructures

Abstract

m^ÄI&";.ÄSM' .The demand for spatial metadata to describe spatial data is growing in the networked environment.Yet, currently metadata acquisition and management often play a subordinate role in many organizations and are considered overhead.If at all, metadata are acquired much after the spatial data and are stored in separate repositories.Consequently, there are two independent data sets to manage and update: spatial data and metadata.These are often redundant and inconsistent, as it is not always clear which information is metadata and which is spatial data.
