Running the embedded NanoSparqlServer

Deploying a SPARQL servlet endpoint

HTTP METHODS

Query

GET or POST

GET [/namespace/NAMESPACE] ?query=...

-OR-

POST [/namespace/NAMESPACE] ?query=...

The response body is the result of the query.

Update

DELETE with Query

DELETE [/namespace/NAMESPACE] ?query=...

Where query is a CONSTRUCT or DESCRIBE query. Statements are materialized using the query from the addressed namespace are deleted from that namespace.

Note: To avoid materializing the statements, this runs the query against the last commit time. This is done while it is holding the unisolated connection which prevents concurrent modifications. Therefore the entire QUERY + DELETE operation is ACID.

DELETE with Body

POST [/namespace/NAMESPACE]
 ...
Content-Type
 ...

BODY

BODY contains RDF statements according to the specified Content-Type. Statements parsed from the BODY are deleted from the addressed namespace.

Status

GET /status
