SPARQL Graph Store Protocol support for Linked Data pipelines.
This package provides operations to read and write from a SPARQL Graph Store.
The operation names match the HTTP methods in lower case.
This operation reads a named graph from the given SPARQL Graph Store.
A Readable stream of RDF/JS Quad objects is returned.
The following options are supported:
-
endpoint: The URL of the Graph Store endpoint as a string. -
graph: The named graph which should be read as a string or RDF/JS Term. The default graph will be read if an empty string is given or the option is not given at all. -
user: User for basic authentication. -
password: Password for basic authentication.
This operation appends quads to the given SPARQL Graph store.
A Writable stream of RDF/JS Quad objects is returned.
The following options are supported:
-
endpoint: The URL of the graph store endpoint as a string. -
user: User for basic authentication. -
password: Password for basic authentication. -
maxQuadsPerRequest: The maximum number of quads per request until a new request is made. (default: 500000)
