Integration of Spatial XML Documents With RDF
Overview The fact that GML is an XML encoding allows it to be queried. In order to query a GML document they have designed a query language over GML/XML enriched with spatial operators. This query language has an underlying data model and algebra that supplies the semantics of the query language. This paper proposes an approach for integrating Geospatial data on the Web, stored in GML documents, using the Spatial Query language. This approach has been inspired by Web Portals technology for retrieving Geospatial information. They have used ontologies to solve the semantic heterogeneity between different GML documents.
