16.9.4. SPARQL Insert using LOAD

SPARQL INSERT operation can be done using the LOAD features:


SPARQL INSERT INTO <..> { .... } [[FROM ...] { ... }]

SPARQL LOAD <x> [INTO <y>]

-- <ResourceURL> will be the Graph IRI of the loaded data:
SPARQL LOAD <ResourceURL>

Examples:

  1. Load from ISQL: 

    SPARQL insert in graph <http://mygraph.com>
{
  <http://example.com/dataspace/Kingsley#this>
  <http://www.w3.org/1999/02/22-rdf-syntax-ns#type>
  <http://rdfs.org/sioc/ns#User> .

  <http://example.com/dataspace/Kingsley#this>
  <http://rdfs.org/sioc/ns#id>
  <Kingsley> .

  <http://example.com/dataspace/Caroline#this>
  <http://www.w3.org/1999/02/22-rdf-syntax-ns#type>
  <http://rdfs.org/sioc/ns#User> .

 <http://example.com/dataspace/Caroline#this>
  <http://rdfs.org/sioc/ns#id>
  <Caroline> .

   <http://example.com/dataspace/Matt#this>
  <http://www.w3.org/1999/02/22-rdf-syntax-ns#type>
  <http://rdfs.org/sioc/ns#User> .

  <http://example.com/dataspace/Matt#this>
  <http://rdfs.org/sioc/ns#id>
  <Matt> .

   <http://example.com/dataspace/demo#this>
  <http://www.w3.org/1999/02/22-rdf-syntax-ns#type>
  <http://rdfs.org/sioc/ns#User> .

  <http://example.com/dataspace/demo#this>
  <http://rdfs.org/sioc/ns#id>
  <demo> .};

  2. Load from .rq file:

    1. Create DAV collection which is visible to public, for ex: http://example.com/DAV/tmp

    2. Upload to the DAV collection the following file for ex. with name listall.rq and with the following content: 

      SPARQL
PREFIX rdf: <http://www.w3.org/1999/02/22-rdf-syntax-ns#>
PREFIX rdfs: <http://www.w3.org/2000/01/rdf-schema#>
PREFIX sioc: <http://rdfs.org/sioc/ns#>
SELECT ?x ?p ?o
FROM <http://mygraph.com>
WHERE
  {
    ?x rdf:type sioc:User .
    ?x ?p ?o.
    ?x sioc:id ?id .
    FILTER REGEX(str(?id), "^King")
  }
ORDER BY ?x

    3. Execute from ISQL the following command: 

      SQL>SPARQL
load bif:concat ("http://", bif:registry_get("URIQADefaultHost"), "/DAV/tmp/listall.rq") into graph <http://myNewGraph.com>;

      As result should be shown:

      callret-0
VARCHAR
_______________________________________________________________________________

Load <http://example.com/DAV/tmp/listall.rq> into graph <http://myNewGraph.com> -- done

1 Rows. -- 321 msec.

  3. Load from Resource URL: 

    SQL> SPARQL LOAD <http://www.w3.org/People/Berners-Lee/card#i>;
callret-0
VARCHAR
_______________________________________________________________________________

Load <http://www.w3.org/People/Berners-Lee/card#i> into graph <http://www.w3.org/People/Berners-Lee/card#i> -- done

1 Rows. -- 703 msec.
