AB: Data interoperability across heterogeneous systems can be hampered by differences in terminology, particularly when multiple scientific communities are involved. To reconcile differences in semantics, a common semantic framework was created as a collection of ontologies. Such a shared understanding of concepts enables ontology-aware software tools to understand the meaning of terms in documents and web pages. The ontologies were created as part of the Semantic Web for Earth and Environmental Terminology (SWEET) prototype. The ontologies provide a representation of Earth system science knowledge and associated data, organized in a scalable structure, bulding on the keywords developed by the NASA Global Change Master Directory (GCMD). An integrated search tool consults the ontologies to enable searches without an exact term match. The ontologies can be used within other applications (such as Earth Science Markup Language descriptors) and future semantic web services in Earth system science.
