Abstract: This is
a progress report on the federated data system, DataFed,
partially supported by a NASA REASoN project. In
DataFed, the distributed data sources
are federated by applying a universal, multi-dimensional data model.
The semantic homogenization is accomplished by wrapper services. Data
processing is performed through web services, which themselves can be
distributed. Data processing applications are created by the composition of the
distributed service components. In order to compose the web services a
view-based framework is utilized. As part of the composition framework
strong reference standards are used to establish interoperability of the
service components. In this work we have adapted the OGC web coverage service
as a standard protocol for Earth Science data access. This report will
summarize our experiences with the OGC WCS based service composition. The
report will include the results of our participation in the GALEON
(Geo-interface to Atmosphere, Land, Earth, Ocean netCDF)
Interoperability Experiment as well as in the OGC GEOS Services Network (GSN).
