What?

This guide contains Virtuoso SPARQL 1.1. CREATE Usage examples queries which you can run against any SPARQL endpoint that supports SPARQL 1.1 and the ability to allow a verified user perform INSERT operations.

Why?

Use to add a named graph in the RDF Quad Store.

How?

Here are some examples showcasing Virtuoso's support for this functionality:

CREATE Example

This example creates named graph identified by the IRI <urn:sparql:tests:create:data> :

  1. Assume the following Raw Data Representation in Turtle: 

    <#book1> <#price> 41 .
<#book2> <#price> 42 .
<#book3> <#price> 43 .
<#book4> <#price> 44 .

  2. Create a named graph identified by the IRI <urn:sparql:tests:create:data> : 

    CREATE GRAPH <urn:sparql:tests:create:data>;

  3. Load the sample data: 

    INSERT DATA
  { 
    GRAPH <urn:sparql:tests:create:data> 
      { 
        <#book1> <#price> 41 . 
        <#book2> <#price> 42 . 
        <#book3> <#price> 43 . 
        <#book4> <#price> 44 .  
      } 
  }

  4. Query <urn:sparql:tests:create:data> graph data: 

    SELECT * 
FROM <urn:sparql:tests:create:data> 
WHERE 
  {
    ?s ?p ?o
  }
