16.19.RDF Graph Replication
The following section demonstrates how to replicate graphs from one Virtuoso instance to (an)other Virtuoso instance(s), using the RDF Replication Feature.
Terms used in this section:
-
Host Virtuoso Instance
, aka the publisher: the instance where we will insert RDF data into a Named Graph; then create a publication of this graph.
-
Destination Virtuoso Instance
, aka the subscriber: the instance which will subscribe to the publication from the Host Virtuoso Instance.
The basic outline:
-
First, use the Virtuoso Conductor on a Host Virtuoso Instance to publish a named graph.
-
Then, use the Virtuoso Conductor on a Destination Virtuoso Instance to subscribe to deltas from the published graph.
-
Finally, see how a change in the publisher's graph will appear in the subscriber's graph.
