Detailed Description

Virtuoso specific adjustments for GenericRepositoryConnector

Specific modifications of the SPARQL database implementation for Virtuoso. In particular, Virtuoso does not support SPARQL Update but only the non-standard SPARUL protocol that requires different syntax for update queries. If future versions of Virtuoso support SPARQL Update, the standard SPARQL database connector should work properly.

Virtuoso uses the SPARQL query endpoint for updates as well. So both

$smwgSparqlEndpoint['update'] and
$smwgSparqlEndpoint['query'] should be something like 'http://localhost:8890/sparql/'.
$smwgSparqlEndpoint['data'] should be left empty.

A graph is always needed, i.e., $smwgSparqlDefaultGraph must be set to some graph name (URI).

Known limitations: (might be fixed in recent Virtuoso versions, please let us know)

Data endpoint not tested: $smwgSparqlEndpoint['data'] should be left empty
Numerical datatypes are not supported properly, and Virtuoso will miss query results when query conditions require number values. This also affects Type:Date properties since the use numerical values for querying.
Some edit (insert) queries fail for unknown reasons, probably related to unusual/complex input data (e.g., using special characters in strings); errors will occur when trying to store such values on a page.
Virtuoso stumbles over XSD dates with negative years, even if they have only four digits as per ISO. Trying to store such data will cause errors.

Member Function Documentation

◆ delete()

SMW\SPARQLStore\RepositoryConnectors\VirtuosoRepositoryConnector::delete	(	$deletePattern,
		$where,
		$extraNamespaces = `[]`
	)

DELETE wrapper. The function declares the standard namespaces wiki, swivt, rdf, owl, rdfs, property, xsd, so these do not have to be included in $extraNamespaces.

Parameters

$deletePattern	string CONSTRUCT pattern of tripples to delete
$where	string condition for data to delete
$extraNamespaces	array (associative) of namespaceId => namespaceUri

Returns: boolean stating whether the operations succeeded

Implements SMW\SPARQLStore\RepositoryConnection.

◆ deleteData()

SMW\SPARQLStore\RepositoryConnectors\VirtuosoRepositoryConnector::deleteData	(	$triples,
		$extraNamespaces = `[]`
	)

DELETE DATA wrapper. The function declares the standard namespaces wiki, swivt, rdf, owl, rdfs, property, xsd, so these do not have to be included in $extraNamespaces.

Parameters

$triples	string of triples to delete
$extraNamespaces	array (associative) of namespaceId => namespaceUri

Returns: boolean stating whether the operations succeeded

◆ doUpdate()

SMW\SPARQLStore\RepositoryConnectors\VirtuosoRepositoryConnector::doUpdate ( $sparql )

Execute a SPARQL update and return a boolean to indicate if the operations was successful.

Virtuoso expects SPARQL updates to be posted using the "query" parameter (rather than "update").

Parameters

$sparql string with the complete SPARQL update query (INSERT or DELETE)

Returns: boolean

Implements SMW\SPARQLStore\RepositoryConnection.

◆ insertData()

SMW\SPARQLStore\RepositoryConnectors\VirtuosoRepositoryConnector::insertData	(	$triples,
		$extraNamespaces = `[]`
	)

INSERT DATA wrapper. The function declares the standard namespaces wiki, swivt, rdf, owl, rdfs, property, xsd, so these do not have to be included in $extraNamespaces.

Parameters

$triples	string of triples to insert
$extraNamespaces	array (associative) of namespaceId => namespaceUri

Returns: boolean stating whether the operations succeeded

◆ insertDelete()

SMW\SPARQLStore\RepositoryConnectors\VirtuosoRepositoryConnector::insertDelete	(	$insertPattern,
		$deletePattern,
		$where,
		$extraNamespaces = `[]`
	)

INSERT DELETE wrapper. The function declares the standard namespaces wiki, swivt, rdf, owl, rdfs, property, xsd, so these do not have to be included in $extraNamespaces.

Parameters

$insertPattern	string CONSTRUCT pattern of tripples to insert
$deletePattern	string CONSTRUCT pattern of tripples to delete
$where	string condition for data to delete
$extraNamespaces	array (associative) of namespaceId => namespaceUri

Returns: boolean stating whether the operations succeeded
