Ontology-based Geographic Information Semantic Metadata Integration

摘要：

Metadata is important to facilitate data sharing among Geospatial Information Communities in distributed environment.For unanimous understanding and standard production of metadata annotations,metadata specifications are documented such as Geographic Information Metadata Standard (ISO19115-2003),the Content Standard for Digital Geospatial Metadata (CSDGM),and so on.Though these specifications provide frameworks for description of geographic data,there are two problems which embarrass sufficiently data sharing.One problem is that specifications are lack of domainspecific semantics.Another problem is that specifications can not always solve semantic heterogeneities.To solve the former problem,an ontology-based geographic information metadata extension framework is proposed which can incorporate domain-specific semantics.Besides,for solving the later problem,metadata integration mechanism based on the proposed extension is studied.In this paper,integration of metadata is realized through integration of ontologies.So integration of ontologies is also discussed.By ontology-based geographic information semantic metadata integration,sharing of geographic data is realized more efficiently.
