NAME
XML::NewsML_G2 - generate NewsML-G2 news items
VERSION
0.2.0
SYNOPSIS
use XML::NewsML_G2;
my $ni = XML::NewsML_G2::News_Item_Text->new(%args);
my $writer = XML::NewsML_G2::Writer_2_15(news_item => $ni);
my $dom = $writer->create_dom();DESCRIPTION
This module tries to implement the creation of XML files conforming to the NewsML-G2 specification as published by the IPTC. It does not aim to implement the complete standard, but to cover the most common use cases in a best-practice manner.
For the full specification of the format, visit http://www.iptc.org/site/News_Exchange_Formats/NewsML-G2/. For a quick introduction, you might prefer the Quick Start Guides.
CURRENT STATUS
The implementation currently supports text, picture, video, audio, graphics, as well as multimedia packages and slideshows.
Version 2.15 is the latest version of the standard supported by this software, and should be your first choice. Using versions 2.9 and 2.12 is deprecated, and support for it will beremoved in future releases. Draft version 2.17 is unsupported, but will evolve into 2.18 when it is finalised.
SCHEMES AND CATALOGS
Before starting to use schemes or catalogs with this module, read the chapter 13 of the NewsML-G2 implementation guide. Go on, do it now. I'll wait.
You don't need to use either schemes or catalogs in order to use this module, unless you are required to do so by the NewsML-G2 standard (e.g. the service attribute). If you specify a value for such an attribute and don't add a corresponding scheme, creating the DOM tree will die.
For all attributes where a scheme is not required by the standard, you can start without specifying anything. In that case, a literal attribute will be created, with the value you specified in the qcode attribute. For instance:
my $org = XML::NewsML_G2::Organisation->new(name => 'Google', qcode => 'gogl');
$ni->add_organisation($org);will result in this output:
<subject type="cpnat:organisation" literal="org#gogl">
<name>Google</name>
</subject>If the qcodes used in your organisation instances are part of a controlled vocabulary, you can convey this information by creating a XML::NewsML_G2::Scheme instance, specifying a custom, unique uri for your vocabulary, and registering it with the XML::NewsML_G2::Scheme_Manager:
my $os = XML::NewsML_G2::Scheme->new(alias => 'xyzorg',
uri => 'http://xyz.org/cv/org');
my $sm = XML::NewsML_G2::Scheme_Manager->new(org => $os);The output will now contain an inline catalog with your scheme:
<catalog>
<scheme alias="xyzorg" uri="http://xyz.org/cv/org"/>
</catalog>and the literal will be replaced by a qcode:
<subject type="cpnat:organisation" qcode="xyzorg:gogl">
<name>Google</name>
</subject>If you have multiple schemes, you can package them together into a single catalog, which you publish on your website. Simply specify the URL of the catalog when creating the XML::NewsML_G2::Scheme instance:
my $os = XML::NewsML_G2::Scheme->new(alias => 'xyzorg',
catalog => 'http://xyz.org/catalog_1.xml');and the inline catalog will be replaced with a link:
<catalogRef href="http://xyz.org/catalog_1.xml"/>API
