Abstract:
A cascaded RDF system includes a local RDF site coupled to a source of data, a remote RDF site, and at least one intermediate RDF site, interposed between the local RDF site and the remote RDF site. Data written by the source of data to the local RDF site is propagated through the at least one intermediate RDF site to be stored at the remote RDF site. The source of data may be a host. There may be more than one intermediate RDF site. The cascaded RDF system may also include an additional remote RDF site, coupled to one of the at least one intermediate RDF site.
