Configuration for connecting to arbitrary SPARQL HTTP backend¤

Use the following set of properties to connect to arbitrary HTTP SPARQL services.

Configuration example:

store:
  type: http
  authorization: REWRITE_FROM
  http:
    query-endpoint-url: "http://localhost:7200/repositories/cmem"
    update-endpoint-url: "http://localhost:7200/repositories/cmem/statements"
    graph-store-endpoint-url: "http://localhost:7200/repositories/cmem/rdf-graphs/service"
    username: "user"
    password: "password"

Property: store.type

The type of the store must be set to “http”

Category	Value
Default	http
Required	true
Valid values	HTTP

Environment	STORE_HTTP_QUERY_ENDPOINT_URL

Property: store.http.update-endpoint-url

Use this property to configure the endpoint to which SPARQL 1.1 updates are sent.

Required	true
Valid values	string
Environment	STORE_HTTP_UPDATE_ENDPOINT_URL

Property: store.http.graph-store-endpoint-url

Use this property to configure the endpoint to SPARQL 1.1 Graph Store Protocol requests are sent.
