Paper Abstract

Successful data sharing is important to integrating information between the Earth Science and geographic information communities for knowledge discovery. The Open-source Project for a Network Data Access Protocol (OPeNDAP) is a data transport architecture and protocol widely used by earth scientists. However, because the DAP and OGC protocols are incompatible. OPeNDAP lacks effective tools to access the OGC data. To solve this problem, middleware between the OGC and DAP protocols, must perform two functions--data discovery and data access. This paper discusses implementation of the data discovery component. This data discovery component first converts an OGC catalog to a THREDDS catalog encoded in XML, and then provides the XML file to the OPeNDAP client. By developing a catalog component of the middleware, the implementation enables OPeNDAP clients to discover data cataloged in OGC data catalogs.
