AB: We have developed an application of semantic web methods and technologies to address the integration of interdisciplinary earth-science datasets. The specific use case addresses seeking and using atmospheric chemistry and volcano geochemistry datasets. We have developed an integration framework based on semantic descriptions (ontologies) of the linking relations between the application domains. In doing this, we have extensively leveraged and existing ontology frameworks such as SWEET, VSTO and GEON as well as included extentions of them when needed. We present the components of this application, including the ontologies, the registration of datasets with ontologies at several levels of granularity, the data sources, and application results from the use case. We will also present the cur rent and near-future capabilities we are developing. This work arises from the Semantically-Enabled Science Data Integration (SESDI) project, which is an NASA/ESTO/ACCESS-funded project performed in part by Rensselaer Polytechnic Institute, the High Altitude Observatory at the National Center for Atmospheric Research (NCAR), McGuinness Associates, NASA/JPL and Virginia Polytechnic University.
