Net::Trackback::Data(3User Contributed Perl DocumentatiNet::Trackback::Data(3)

NAME
       Net::Trackback::Data - an object	representing Trackback data to a
       pingable	resource.

SYNOPSIS
	use Net::Trackback::Data;
	my $data = Net::Trackback::Data->new();
	$data->url('http://www.timaoutloud.org/archives/000206.html');
	$data->ping('http://www.timaoutloud.org/cgi/mt/mt-tb.cgi/105');
	$data->title('The Next Generation of TrackBack:	A Proposal');
	$data->description('I thought it would be helpful to draft some
	   suggestions for consideration for the next generation (NG)
	   of the interface.');
	print $data->to_rdf."\n";

METHODS
       Net::Trackback::Data->new([$hashref])
	   Constuctor method. It will initialize the object if passed a	hash
	   reference. Recognized keys are title, identifier, subject,
	   description,	creator, date, source, publisher, contributor, type,
	   format, language, relation, coverage, rights	and ping. (These are
	   all the Dublin Core Metadata	Element	Set except for ping of
	   course.) These keys correspond to the methods like named methods.

       Net::Trackback::Data->parse($rdf)
	   A method that parses	(albeit	crude using regex) Trackback data from
	   a string of RDF and returns a data object. In the event a bad or
	   incomplete data has been passed in the method will return "undef".
	   The error message can be retreived with the "errstr"	method.	One
	   required parameter, a string	containing RDF.	See the	list of
	   recognized keys in the new method.

	   NOTE: This module does not use a XML	or RDF parser therefore
	   namespaces are not handled properly.	The prefixes are assumed to be
	   fixed to a specific URI. This is consistent with the	reference
	   implementation standalone Trackback code in which the module	was
	   originally based.

       $data->identifier([$url])
	   Accessor to the resource's URL that can be pinged. A	value is
	   required for	Trackback clients to process the data. If an optional
	   parameter is	passed in the value is set.

       $data->ping([$url])
	   Accessor to the ping	URL of the resource. A value is	required for
	   Trackback clients to	process	the data. If an	optional parameter is
	   passed in the value is set.

       $data->title([$title])
       $data->subject([$subject])
       $data->description([$description])
       $data->creator([$creator])
       $data->date([$date])
       $data->source([$source])
       $data->publisher([$publisher])
       $data->contributor([$contributor])
       $data->type([$type])
       $data->format([$format])
       $data->language([$language])
       $data->relation([$relation])
       $data->coverage([$coverage])
       $data->rights([$rights])
	   Accessor methods to the remaining Dublin Core Metadata Element Set.
	   If an optional parameter is passed in the value is set. All are
	   optional for	Trackback client discovery. Use	as needed. (Title and
	   description are highly recommended by this modules author.)

       $data->to_hash
	   Returns a hash of the object's current state.

       $data->to_rdf
	   Returns an RDF representation of the	object metadata	that can be
	   inserted into an (X)HTML page for discovery by Trackback clients.

   Errors
       This module is a	subclass of Class::ErrorHandler	and inherits two
       methods for passing error message back to a caller.

       Class->error($message)
       $object->error($message)
	   Sets	the error message for either the class Class or	the object
	   $object to the message $message. Returns undef.

       Class->errstr
       $object->errstr
	   Accesses the	last error message set in the class Class or the
	   object $object, respectively, and returns that error	message.
