AnnoTerra is a Semantic Web application that presents enhanced earth science news feeds. It makes focused semantic searches for interrelated resources registered in NASA knowledge catalogs using concepts and relationships from the earth science field. Presently, it uses three NASA data sources are used: the Earth Observatory, the Global Change Master Directory, and the Earth Observing System Clearing House. The project idea was to enhance existing data sources with additional, user-provided information. Three challenges existed: creating an ontology in a vast realm (earth science); implementing equivalencies, mappings, and transformations between ontological concepts (the data catalogs' metadata structures); and performing the semantic associations between real-world items and their conceptual representations in the form of ontologies. The authors explore and detail an extensible solution using open standards (such as OWL).
