IGraph	g	Graph to query.

LoadFromEmbeddedResource(IGraph, String)

Loads RDF data from an Embedded Resource into a Graph.

Declaration

public static void LoadFromEmbeddedResource(this IGraph g, string resource)

Parameters

Type	Name	Description
IGraph	g	Graph to load into.
System.String	resource	Assembly qualified name of the resource to load from.

Remarks

This is just a shortcut to using the static Load() methods from the EmbeddedResourceLoader class located in the VDS.RDF.Parsing namespace.

LoadFromEmbeddedResource(IGraph, String, IRdfReader)

Loads RDF data from an Embedded Resource into a Graph.

Declaration

public static void LoadFromEmbeddedResource(this IGraph g, string resource, IRdfReader parser)

Parameters

Type	Name	Description
IGraph	g	Graph to load into.
System.String	resource	Assembly qualified name of the resource to load from.
IRdfReader	parser	Parser to use.

Remarks

This is just a shortcut to using the static Load() methods from the EmbeddedResourceLoader class located in the VDS.RDF.Parsing namespace.

LoadFromFile(IGraph, String)

Loads RDF data from a file into a Graph.

Declaration

public static void LoadFromFile(this IGraph g, string file)

Parameters

Type	Name	Description
IGraph	g	Graph to load into.
System.String	file	File to load from.

Remarks

This is just a shortcut to using the static Load() methods from the FileLoader class located in the VDS.RDF.Parsing namespace.

Note: FileLoader will assign the Graph a file URI as it's Base URI unless the Graph already has a Base URI or is non-empty prior to attempting parsing. Note that any Base URI specified in the RDF contained in the file will override this initial Base URI. In some cases this may lead to invalid RDF being accepted and generating strange relative URIs, if you encounter this either set a Base URI prior to calling this method or create an instance of the relevant parser and invoke it directly.

If a File URI is assigned it will always be an absolute URI for the file.

LoadFromFile(IGraph, String, IRdfReader)

Loads RDF data from a file into a Graph.

Declaration

public static void LoadFromFile(this IGraph g, string file, IRdfReader parser)

Parameters

Type	Name	Description
IGraph	g	Graph to load into.
System.String	file	File to load from.
IRdfReader	parser	Parser to use.

Remarks

This is just a shortcut to using the static Load() methods from the FileLoader class located in the VDS.RDF.Parsing namespace.

Note: FileLoader will assign the Graph a file URI as it's Base URI unless the Graph already has a Base URI or is non-empty prior to attempting parsing. Note that any Base URI specified in the RDF contained in the file will override this initial Base URI.

LoadFromString(IGraph, String)

Loads RDF data from a String into a Graph.

Declaration

public static void LoadFromString(this IGraph g, string data)

Parameters

Type	Name	Description
IGraph	g	Graph to load into.
System.String	data	Data to load.

Remarks

This is just a shortcut to using the static Parse() methods from the StringParser class located in the VDS.RDF.Parsing namespace.

LoadFromString(IGraph, String, IRdfReader)

Loads RDF data from a String into a Graph.

Declaration

public static void LoadFromString(this IGraph g, string data, IRdfReader parser)

Parameters

Type	Name	Description
IGraph	g	Graph to load into.
System.String	data	Data to load.
IRdfReader	parser	Parser to use.

Remarks

This is just a shortcut to using the static Parse() methods from the StringParser class located in the VDS.RDF.Parsing namespace.

LoadFromUri(IGraph, Uri)

Loads RDF data from a URI into a Graph.

Declaration

public static void LoadFromUri(this IGraph g, Uri u)

Parameters

Type	Name	Description
IGraph	g	Graph to load into.
System.Uri	u	URI to load from.

Remarks

This is just a shortcut to using the static Load() methods from the UriLoader class located in the VDS.RDF.Parsing namespace.

Note: UriLoader will assign the Graph the source URI as it's Base URI unless the Graph already has a Base URI or is non-empty prior to attempting parsing. Note that any Base URI specified in the RDF contained in the file will override this initial Base URI. In some cases this may lead to invalid RDF being accepted and generating strange relative URIs, if you encounter this either set a Base URI prior to calling this method or create an instance of the relevant parser and invoke it directly.

LoadFromUri(IGraph, Uri, IRdfReader)

Declaration

public static void LoadFromUri(this IGraph g, Uri u, IRdfReader parser)

Parameters

Type	Name	Description
IGraph	g	Graph to load into.
System.Uri	u	URI to load from.
IRdfReader	parser	Parser to use.

Remarks
