Enumeration Documentation

BackendFeature

Each Backend plugin can support different features. %Soprano defines a list of well-known features that each backend implementation should try to realize. In addition user features can be defined. For this BackendFeatureUser has to be included in the supported features. Then additional features may be reported through Backend.supportedUserFeatures().

\sa Backend.supportedFeatures(), Backend.supportedUserFeatures()

Enumerator:

BackendFeatureNone = 0x0
BackendFeatureAddStatement = 0x1
BackendFeatureRemoveStatements = 0x2
BackendFeatureListStatements = 0x4
BackendFeatureQuery = 0x8
BackendFeatureInference = 0x10
BackendFeatureInferenceOptional = 0x20
BackendFeatureContext = 0x40
BackendFeatureStorageMemory = 0x80
BackendFeatureUser = 0x1000

BackendOption

There are two types of backend settings: boolean flags and key/value pairs. The boolean flags are identified by BackendFlag.

\sa BackendSetting, Backend.createModel()

Enumerator:

BackendOptionNone = 0x0
BackendOptionStorageMemory = 0x1
BackendOptionEnableInference = 0x2
BackendOptionStorageDir = 0x4
BackendOptionUser = 0x1000

RdfSerialization

Different types of RDF serialization.

Enumerator:

SerializationUnknown = 0x0 The serialization is unknown. < p>
SerializationRdfXml = 0x1 Standard RDF XML serialization < p>
SerializationN3 = 0x2 Notation 3: http: www.w3.org DesignIssues Notation3 < p>
SerializationNTriples = 0x4 N-Triples as defined by W3: http: www.w3.org TR rdf-testcases #ntriples < p>
SerializationTurtle = 0x8 Turtle - Terse RDF Triple Language: http: www.dajobe.org 2004 01 turtle < p>
SerializationTrig = 0x10 TriG - Turtle + Named Graphs: http: sites.wiwiss.fu-berlin.de suhl bizer TriG < p>
SerializationNQuads = 0x20 N-Quads extends over N-Triples in that it adds an optional context node. < p>
SerializationUser = 0x0 The user type can be used to introduce unknown RDF serializations by name < p>

Function Documentation

Soprano.Model createModel	(	[Soprano.BackendSetting]	settings=QList()
	)

Creates a new RDF storage using the backend set via setUsedBackend. The caller takes ownership and has to care about deletion.

Parameters:

settings

The settings that should be used to create the Model. Backend implementations should never ignore settings but rather return 0 if an option is not supported. Backends can, however, define their own default settings.

\sa Model, Backend.createModel

Soprano.Backend discoverBackendByFeatures	(	Soprano.BackendFeatures	features,
		QStringList	userFeatures=QStringList()
	)

Find a backend plugin by its features.

Parameters:

features

The features that are requested.

Parameters:

userFeatures

If features contain Soprano.BackendFeatureUser this paramter states the additionally requested user features.

Returns:: a backend that supports the features defined in features.

\sa PluginManager.discoverBackendByFeatures()

Soprano.Backend discoverBackendByName	(	QString	name
	)

Find a backend plugin by its name.

Returns:: the backend specified by name or null if could not be found.

Soprano.RdfSerialization mimeTypeToSerialization	(	QString	mimetype
	)

Parse a mimetype and match it to the Soprano.RdfSerialization enum.

Returns:: the Soprano.RdfSerialization type that matches mimetype or SerializationUnknown if the mimetype could not be parsed. Be aware that Soprano is very lax in parsing the mimetype, i.e. you can use simple strings like 'trig' or 'n-quads' instead of the proper mimetype for convenience.

QString serializationMimeType	(	Soprano.RdfSerialization	serialization,
		QString	userSerialization=QString()
	)

Get the mimetype string of a serialization.

Parameters:

serialization

The serialization the mimetype is wanted for.

Parameters:

userSerialization

If serialization is SerializationUser then this is the user defined serialization. (this parameter is added for convinience to avoid having an additional check before using this method.)

Returns:: The mimetype of serialization, an empty string is serialization is SerializationUnknown, or

userSerialization if serialization is SerializationUser.

setUsedBackend	(	Soprano.Backend	a0
	)

By default and if available backend "redland" is used.

Soprano.Backend usedBackend ( self )
