Query
The Query Service Endpoint, the Catalog Framework, and the CatalogProvider are key components for processing a query request as well. The Endpoint bundle contains a Web service that exposes the interface to query for Metacards. The Endpoint calls the CatalogFramework to execute the operations of its specification. The CatalogFramework relies on the CatalogProvider to execute the actual query. Optional PreQuery and PostQuery Catalog Plugins may be invoked by the CatalogFramework to modify the query request/response prior to the Catalog Provider processing the query request and provides the query response. If a CatalogProvider is not configured and no other remote Sources are configured a fault will be returned. It is possible to have only remote Sources configured and no local CatalogProvider configured and be able to execute queries to specific remote Sources by specifying the site name(s) in the query request.
