Syntax

public class HtmlWriter : BaseHtmlWriter, IHtmlWriter, IRdfWriter, INamespaceWriter

Remarks

Since not all Triples can be embedded into XHTML those Triples will not have RDFa generated for them but all Triples will be shown in a human readable format. Triples that can be serialized are roughly equivalent to anything that can be serialized in Turtle i.e. URI/BNode subject, URI predicates and URI/BNode/Literal object.

If you encode Triples which have values datatyped as XML Literals with this writer then round-trip Graph equality is not guaranteed as the RDFa parser will add appropriate Namespace declarations to elements as required by the specification.

Properties

DefaultNamespaces

Gets/Sets the Default Namespaces to use for writers.

Declaration

public INamespaceMapper DefaultNamespaces { get; set; }

Property Value

Type	Description
INamespaceMapper

Triples that can be serialized are roughly equivalent to anything that can be serialized in Turtle i.e. URI/BNode subject, URI predicates and URI/BNode/Literal object.

Methods

Save(IGraph, TextWriter, bool)

Save the Graph to the given Stream as an XHTML Table with embedded RDFa.

Declaration

public void Save(IGraph g, TextWriter output, bool leaveOpen)

Parameters

Type	Name	Description
IGraph	g	Graph to save.
System.IO.TextWriter	output	Stream to save to.
System.Boolean	leaveOpen	Whether to leave output open after writing the graph.

Remarks

Since not all Triples can be embedded into XHTML those Triples will not have RDFa generated for them but all Triples will be shown in a human readable format. Triples that can be serialized are roughly equivalent to anything that can be serialized in Turtle i.e. URI/BNode subject, URI predicates and URI/BNode/Literal object.

If you encode Triples which have values datatyped as XML Literals with this writer then round-trip Graph equality is not guaranteed as the RDFa parser will add appropriate Namespace declarations to elements as required by the specification.

Save(IGraph, TextWriter)

Method for Saving a Graph to a Concrete RDF Syntax via some arbitrary System.IO.TextWriter.

Declaration

public void Save(IGraph g, TextWriter output)

Parameters

Type	Name	Description
IGraph	g	The Graph to Save.
System.IO.TextWriter	output	The System.IO.TextWriter to save the Graph to.

Remarks

Since not all Triples can be embedded into XHTML those Triples will not have RDFa generated for them but all Triples will be shown in a human readable format. Triples that can be serialized are roughly equivalent to anything that can be serialized in Turtle i.e. URI/BNode subject, URI predicates and URI/BNode/Literal object.

If you encode Triples which have values datatyped as XML Literals with this writer then round-trip Graph equality is not guaranteed as the RDFa parser will add appropriate Namespace declarations to elements as required by the specification.

Exceptions

Type	Condition
RdfException	Thrown if the RDF in the Graph is not representable by the Writer.
System.IO.IOException	Thrown if the Writer is unable to write to the underlying storage of the System.IO.TextWriter specified in the output.

Save(IGraph, string, Encoding)

Method for saving a graph to a concrete RDF syntax in a file-based format with a specific text encoding.

Declaration

public void Save(IGraph g, string filename, Encoding fileEncoding)

Parameters

Type	Name	Description
IGraph	g	The graph to save.
string	filename	The path to the file to write to.
System.Text.Encoding	fileEncoding	The text encoding to use when writing the file content.

Remarks

Since not all Triples can be embedded into XHTML those Triples will not have RDFa generated for them but all Triples will be shown in a human readable format. Triples that can be serialized are roughly equivalent to anything that can be serialized in Turtle i.e. URI/BNode subject, URI predicates and URI/BNode/Literal object.

If you encode Triples which have values datatyped as XML Literals with this writer then round-trip Graph equality is not guaranteed as the RDFa parser will add appropriate Namespace declarations to elements as required by the specification.

Exceptions

Type	Condition
RdfException	Thrown if the RDF in the Graph is not representable by the Writer.
System.IO.IOException	Thrown if the Writer is unable to write to the File.

Save(IGraph, string)

Method for Saving a Graph to a Concrete RDF Syntax in a file based format.

Declaration

public void Save(IGraph g, string filename)

Parameters

Type	Name	Description
IGraph	g	The Graph to Save.
string	filename	The filename to save the Graph in.

Remarks

The output will be written in UTF-8 with no byte-order mark specified. To override this behaviour, call either Save(IGraph, string, Encoding) with the specific encoding to use, or Save(IGraph, TextWriter) with a TextWriter created with the required text encoding set.

Exceptions

Type	Condition
RdfException	Thrown if the RDF in the Graph is not representable by the Writer.
System.IO.IOException	Thrown if the Writer is unable to write to the File.

ToString()

Gets the String representation of the writer which is a description of the syntax it produces.

Declaration

public override string ToString()

Returns

Type	Description
string

Overrides

object.ToString()

Remarks

Since not all Triples can be embedded into XHTML those Triples will not have RDFa generated for them but all Triples will be shown in a human readable format. Triples that can be serialized are roughly equivalent to anything that can be serialized in Turtle i.e. URI/BNode subject, URI predicates and URI/BNode/Literal object.

If you encode Triples which have values datatyped as XML Literals with this writer then round-trip Graph equality is not guaranteed as the RDFa parser will add appropriate Namespace declarations to elements as required by the specification.

Events

Warning

Event which is raised if there is a non-fatal error with the RDF being output

Declaration

public event RdfWriterWarning Warning

Event Type

Type	Description
RdfWriterWarning

Remarks
