Ontology-Driven Resource Aggregation Model on Geological Survey Information Grid

摘要

The platform of China Geological Survey Information Grid (CGSI Grid) which is constructed in the distributed heterogeneous network environment is confronted with troubles of discovering, exchanging and describing spatial Data, because it is distributed in different grid nodes and of different formats and types. In order to solve these problems, Ontology-driven Resource Aggregation Model utilizes geological domain ontology description language (OWL) to describe geospatial information and GIS services and extend the semantic information of data, establishes peer-to-pear resource aggregation model, and builds multi-node resource discovery mechanism in distributed grid environments across the whole country, in order to promote the sharing of geospatial data and GIS capabilities, make sure that geological resources are published, discovered, retrieved, invoked automatically and intelligently, and actualize collaborative computing of heterogeneous data.
