---++Load Turtle Example Resource using SPARQL 1.1 LOAD FEATURE
%TOC%
The following example demonstrates how to retrieve triples from remote Turtle resource using the SPARQL 1.1. LOAD Feature.
---+++Prerequisites
The following packages should be installed:
1 [[http://s3.amazonaws.com/opldownload/uda/vad-packages/6.4/virtuoso/conductor_dav.vad][conductor_dav.vad]] package.
1 [[http://s3.amazonaws.com/opldownload/uda/vad-packages/6.4/virtuoso/ods_framework_dav.vad][ods_framework_dav.vad]] package.
1 [[http://s3.amazonaws.com/opldownload/uda/vad-packages/6.4/virtuoso/cartridges_dav.vad][cartridges_dav.vad]] package.
---+++Steps
1 Assume the following [[https://s3.amazonaws.com/webid-sandbox/Enhanced-Turtle-Example.ttl][https://s3.amazonaws.com/webid-sandbox/Enhanced-Turtle-Example.ttl]] public turtle resource.
1 [[http://ods.openlinksw.com/dataspace/dav/wiki/ODS/ODSGenerateX509Certificate][Generate an X.509 Certificate hosted WebID]].
1 [[VirtSPARQLSSL][Create SPARQL-WebID based Endpoint]].
1 Go to http://<cname>:<port>/conductor, where <cname>:<port> are replaced by your local server values.
1 Log in as user "dba" or another user with DBA privileges
1 Go to Linked Data -> Access Controls -> SPARQL-WebID :
%BR%%BR%
 %BR%%BR%
1 In the shown form:
1 Enter for Web ID for ex.:
http://id.myopenlink.net/dataspace/person/demo#this
1 Select "SPARQL Role": "UPDATE".
1 Leave "Use existing User account:" to "none" so to be created a new SQL User associated with the new WebID ACL:
%BR%%BR% %BR%%BR%
1 Click the "Register" button.
1 As result the WebID Protocol ACL will be created and will be associated with the new create SQL Account SPUID1:
%BR%%BR% %BR%%BR%
1 Go to the SPARQL+WebID endpoint https://<cname>:<port>/sparql-webid
1 When challenged for authentication select the user's certificate generated from above:
%BR%%BR% %BR%%BR%
1 The protected SPARQL-WebID Endpoint UI should be presented:
%BR%%BR% %BR%%BR%
1 To verify the Logged In Identity, execute the following query:
select (bif:get_user()) {}
%BR%%BR% %BR%%BR%
%BR%%BR% %BR%%BR%
1 Click back and in order to load triples from our remote example resource, execute the following statement:
load
%BR%%BR% %BR%%BR%
%BR%%BR% %BR%%BR%
1 Check the inserted triples by executing the following query:
SELECT *
FROM
WHERE
{
?s ?p ?o
}
%BR%%BR% %BR%%BR%
%BR%%BR% %BR%%BR%
