ANN: Four modules for RDFa and HTML

[Toby Inkster]

At lunch time today I released the following modules to CPAN:

	- HTML::HTML5::Parser 0.01
	- HTML::HTML5::Sanity 0.01
	- RDF::RDFa::Parser 0.22
	- RDF::RDFa::Parser::Redland 0.22

HTML::HTML5::Parser is a parser for tag soup HTML, which builds an
XML::LibXML::Document object as its output. It uses the HTML5 parsing
algorithm, so the DOM it builds should be more consistent with the DOMs
built by real-world browsers than the other CPAN tag soup parsers. It's
based on the non-CPAN Whatpm::HTML package.

HTML::HTML5::Sanity is used to correct certain oddities with the HTML
DOM produced by HTML::HTML5::Parser. The Parser is "correct" in parsing,
say, an attribute like xml:lang="en" as if it were an attribute called
"xml:lang" in the null namespace - however, the more expected behaviour
is for it to be parsed as an attribute called "lang" in the XML
namespace. Sanity makes the DOM less insane.

RDF::RDFa::Parser and RDF::RDFa::Parser::Redland should hopefully
already be familiar to you. In 0.22, I've added a few more optional
features, like the ability to turn off case-sensitivity for CURIE
prefixes (useful for dealing with HTML, where attribute names are not
case-sensitive). One interesting feature is Auto Config: support for an
HTML <meta> tag that allows the page itself to say which optional
features should be used.

Auto Config is documented here:
