Abstract :
This is a report on the federated data system,DataFed for distributed air quality data. Data sources are federated by applying a universal, multi-dimensional data model. The physical and 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. International Standards and Protocols are used to establish interoperability of the service components. In this work we have adapted the OGC Web services as a standard protocol for air quality data access. This report summarizes our experiences with the OGC W*S based service composition. It includes the results of our participation in the GALEON (geo-interface to atmosphere,land,earth,ocean netCDF) Interoperability experiment.
