Summary: Unresolved prefixed name in SPARQL Query
Product: MediaWiki extensions
Version: any
Platform: PC
OS/Version: Linux
Status: NEW
Severity: blocker
Priority: Unprioritized
Component: Semantic MediaWiki
AssignedTo: wikibugs-l@lists.wikimedia.org
ReportedBy: icarnev...@imolinfo.it
CC: jeroen_ded...@yahoo.com, mar...@semantic-mediawiki.org
Classification: Unclassified
Installed software
- MediaWiki 1.18.0 (r525)
- Semantic MediaWiki (Version 1.6.1) (r525)
I use SMW whit Joseki as default store.
The configuration in my LocalSettings.php is the following
$smwgDefaultStore = 'SMWSparqlStore';
$smwgSparqlQueryEndpoint = 'http://localhost:8080/joseki/sparql';
$smwgSparqlUpdateEndpoint = 'http://localhost:8080/joseki/update/service';
$smwgSparqlDataEndpoint = ''; # optional location of SPARQL over HTTP service
i have this error on browser while generating SPARQL DELETE query:
Unexpected non-MediaWiki exception encountered, of type
"SMWSparqlDatabaseError"
exception 'SMWSparqlDatabaseError' with message 'A SPARQL query error
has occurred

The problem is that in the PREFIX list i don't have the "state-instances"
prefix.
In SMW_SparqlDatabase.php the method
public function delete( $deletePattern, $where, $extraNamespaces = array() )
"extraNamespaces" that is an array (associative) of namespaceId =>
namespaceUri,
and it contains prefix different from wiki, swivt, rdf, owl, rdfs, property,
xsd.
The method
SMW_SparqlStore.php:deleteSparqlData( SMWExpResource $expResource )
invoke SMW_SparqlDatabase.php:delete like
smwfGetSparqlDatabase()->delete( "$resourceUri ?p ?o", "$resourceUri ?p ?o" );
and "extraNamespaces" isn't in the parameters list.
Solution:
1) Fill extraNamespaces int he following way
$extraNamespaces = array();
$extraNamespaces[$expResource->getNamespaceId()]=$expResource->getNamespace();
2) Pass the filled array to SMW_SparqlDatabase.php:delete method like
smwfGetSparqlDatabase()->delete( "$resourceUri ?p ?o", "$resourceUri ?p
?o", $extraNamespaces );
and the result is
/**
* Delete from the SPARQL database all data that is associated with the
* given resource.
*
* @param $expResource SMWExpResource
* @return boolean success
*/
protected function deleteSparqlData( SMWExpResource $expResource ) {
$resourceUri = SMWTurtleSerializer::getTurtleNameForExpElement(
$expResource );
$masterPageProperty = SMWExporter::getSpecialNsResource( 'swivt',
'masterPage' );
$masterPagePropertyUri =
SMWTurtleSerializer::getTurtleNameForExpElement( $masterPageProperty );
$extraNamespaces = array();
$extraNamespaces[$expResource->getNamespaceId()]=$expResource->getNamespace();
$success = smwfGetSparqlDatabase()->deleteContentByValue(
$masterPagePropertyUri, $resourceUri, $extraNamespaces );
if ( $success ) {
return smwfGetSparqlDatabase()->delete( "$resourceUri ?p ?o",
"$resourceUri ?p ?o", $extraNamespaces );
} else {
return false;
}
}
