Design open sharing framework for spatial information in semantic web

Existing spatial information resources in Internet are domain-oriented and GIS platform-dependent. Each spatial information resource is heterogeneous and becomes an information island. How to let those spatial information islands become sharable and interoperable, how to help Internet users locate and access to their interested spatial information fast and accurately,..., are focus problems of Geoscience, and are also key technologies for Digital Earth and Spatial Information Infrastructure. An Open Spatial Information Sharing Framework (OSISF) is presented to attempt to solve those problems. OSISF is a services model that supports spatial information share and interoperation. OSISF separates service and information into different resources in Internet, and metadata is used to describe the features of resource.
