Constructors

RdfAContext()

Create a new empty vocabulary.

Declaration

public RdfAContext()

RdfAContext(string, IEnumerable<KeyValuePair<string, string>>, IEnumerable<KeyValuePair<string, string>>)

Create a new RDFa context with the specified default vocabulary URI, term and prefix mappings.

Declaration

public RdfAContext(string vocabularyUri, IEnumerable<KeyValuePair<string, string>> terms, IEnumerable<KeyValuePair<string, string>> prefixes)

Parameters

Type	Name	Description
string	vocabularyUri	The default vocabulary URI. If null, the context will be defined with no default vocabulary URI.
IEnumerable<KeyValuePair<string, string>>	terms	An enumeration of key value pairs mapping each term to the URI that the term maps to. May be null.
IEnumerable<KeyValuePair<string, string>>	prefixes	An enumeration of key value pairs mapping each prefix to the URI that the prefix maps to. May be null.

RdfAContext(IRdfAContext)

Create a new vocabulary from an existing vocabulary.

Declaration

public RdfAContext(IRdfAContext context)

Parameters

Type	Name	Description
IRdfAContext	context	The base vocabulary to copy.

RdfAContext(IRdfAContext, string, IEnumerable<KeyValuePair<string, string>>, IEnumerable<KeyValuePair<string, Uri>>)

Create a new vocabulary that extends an existing vocabulary and add terms and prefix mappings to it.
