Example for Single RDF Source File Upload

The following example demonstrates how to upload single RDF source file using the Bulk Loading Sequence.

1. Assuming there is a folder with name "tmp" in your FS and it is under a directory specified in the DirsAllowed param defined in your virtuoso ini file.
2. Also assume in the folder "tmp" there is a file named "kidehen.n3" that contains:
   

   
   <http://www.openlinksw.com/dataspace/kidehen@openlinksw.com#this> <http://www.w3.org/1999/02/22-rdf-syntax-ns#type> <http://rdfs.org/sioc/ns#User> .
   <http://www.openlinksw.com/dataspace/kidehen@openlinksw.com#this> <http://www.w3.org/2000/01/rdf-schema#label> 	"Kingsley" .
   <http://www.openlinksw.com/dataspace/kidehen@openlinksw.com#this> <http://rdfs.org/sioc/ns#creator_of> <http://www.openlinksw.com/dataspace/kidehen@openlinksw.com/weblog/kidehen@openlinksw.com%27s%20BLOG%20%5B127%5D/1300> .
   

   
   
3. Make sure the Bulk Loading script is executed.
4. Register the file "kidehen.n3" with graph IRI "http://kidehen.com#":
   

   
   SQL>ld_dir ('tmp', 'kidehen.n3', 'http://kidehen.com#');
   Done. -- 90 msec.
   

   
   
5. Create in the "tmp" folder an empty file with name: kidehen.ext.graph
6. Edit the kidehen.ext.graph by adding the graph IRI, so the content of the file to be:
   

   
   http://kidehen.com#
   

   
   
7. Finally execute:
   

   
   SQL>rdf_loader_run ();
   Done. -- 100 msec.
   

   
   
8. As result on the Server console should be shown notification for the loading is complete:
   

   
   10:21:50 PL LOG: Loader started
   10:21:50 PL LOG: No more files to load. Loader has finished,
   

   
   
9. To check the inserted triples for the given graph, execute:
   

   
   SQL>SPARQL
   SELECT * 
   FROM <http://kidehen.com#>
   WHERE 
     {
       ?s ?p ?o
     }
   ;
     
   s                                                                 p                                                 o
   VARCHAR                                                           VARCHAR                                           VARCHAR
