NAME HTML::Embedded::Turtle - embedding RDF in HTML the crazy way SYNOPSIS use HTML::Embedded::Turtle; my $het = HTML::Embedded::Turtle->new($html, $base_uri); foreach my $graph ($het->endorsements) { my $model = $het->graph($graph); # $model is an RDF::Trine::Model. Do something with it. } DESCRIPTION RDF can be embedded in (X)HTML using simple The rel="meta" stuff is parsed using an RDFa parser, so equivalent RDFa works too. This module parses HTML files containing graphs like these, and allows you to access them each individually; as a union of all graphs on the page; or as a union of just the endorsed graphs. Despite the module name, this module supports a variety of Languages supported are (case insensitive): "Turtle", "NTriples", "RDFJSON", "RDFXML" and "Notation3". Constructor "HTML::Embedded::Turtle->new($markup, $base_uri, \%opts)" Create a new object. $markup is the HTML or XHTML markup to parse; $base_uri is the base URI to use for relative references. Options include: * markup Choose which parser to use: 'html' or 'xml'. The former chooses HTML::HTML5::Parser, which can handle tag soup; the latter chooses XML::LibXML, which cannot. Defaults to 'html'. * rdfa_options A set of options to be parsed to RDF::RDFa::Parser when looking for endorsements. See RDF::RDFa::Parser::Config. The default is probably sensible. Public Methods "union_graph" A union graph of all graphs found in the document, as an RDF::Trine::Model. Note that the returned model contains quads. "endorsed_union_graph" A union graph of only the endorsed graphs, as an RDF::Trine::Model. Note that the returned model contains quads. "graph($name)" A single graph from the page. "graphs" "all_graphs" A hashref where the keys are graph names and the values are RDF::Trine::Models. Some graph names will be URIs, and others may be blank nodes (e.g. "_:foobar"). "graphs" and "all_graphs" are aliases for each other. "endorsed_graphs" Like "all_graphs", but only returns endorsed graphs. Note that all endorsed graphs will have graph names that are URIs. "endorsements" Returns a list of URIs which are the names of endorsed graphs. Note that the presence of a URI $x in this list does not imply that "$het->graph($x)" will be defined. "dom" Returns the page DOM. "uri" Returns the page URI. BUGS Please report any bugs to . Please forgive me in advance for inflicting this module upon you.
