Description

Remote Sources are read-only data Sources that support query operations but cannot be used to create, update, or delete Metacards. 

Types of Remote Sources include:

  • Federated Source — a Remote Source that can be included in federated queries by request or as part of an enterprise query
  • Connected Source — a Source that is included in all local and federated queries, but is hidden from external clients

Remote Sources currently extend the ResourceReader interface. However, a RemoteSource is not treated as a ResourceReader. The getSupportedSchemes() method should never be called on a RemoteSource, thus the suggested implementation for a RemoteSource is to return an Empty Set. The retrieveResource( ... ) and getOptions( ... ) methods will be called and MUST be properly implemented by a RemoteSource.
