Application Schema Mapping based on Ontology: An Approach for GML Storage

Manoj Paul, S.K. Ghosh
2007 2006 1st International Conference on Digital Information Management  
With the proliferation of GML in many geospatial applications and storage support from the standard DBMS, the need arises for the efficient storage mechanism of GML data.  ...  This paper analyses approaches for XML data storage in traditional DBMS and proposes alternative solutions for GML. Every GML document structure is defined in an application schema.  ...  Since the proprietary data are converted to GML in adherence to standard GML application schema for the source, we need to search for the relational schemas, which can best fit a given application schema  ...
