Set Up a Graph Service
Explore how to configure an RDF graph service that simplifies managing multiple RDF graph stores. Learn to track graph endpoints, switch between databases, and unify querying using SPARQL through a common service API.
We’ll set up an RDF graph service to abstract over any RDF graph database that we want to query. The graph service will provide us with a common API for graph management and for sending queries to the graph database.
Public databases
While we will make use of a local RDF graph database for testing, there are also many public RDF graph databases that are available for querying. We’ll try some of these out too. We can query these RDF graph databases through their public SPARQL endpoints.
