If I read correctly in the manual page it is possible to add Dublin Core (DC) metadata to RSS 2.0 feeds, even via the XML::RSS module. I seem to be missing something.

#!/usr/bin/perl use XML::RSS; use strict; use warnings; my $rss = XML::RSS->new (version => '2.0'); $rss->channel(title => 'Example Corp, Inc', link => 'http://example.com', language => 'en', description => 'a one-stop-shop for all your Linux', ); $rss->add_item(title => "GTKeyboard 0.85", permaLink => "http://example.com/1999/06/21/93.html", description => 'blah blah', dc => { creator => 'an author', contributor => 'an editor', }, ); print $rss->as_string; exit(0);
If I run that, I get the following, without the Dublin Core. I was expecting the Dublin Core metadata elements to somehow show up.
<?xml version="1.0" encoding="UTF-8"?> <rss version="2.0" xmlns:blogChannel="http://backend.userland.com/blogChannelModule" > <channel> <title>Example Corp, Inc</title> <link>http://example.com</link> <description>the one-stop-shop for all your Linux</description> <language>en</language> <item> <title>GTKeyboard 0.85</title> <description>blah blah</description> <guid isPermaLink="true">http://freshmeat.net/news/1999/06/21/93.html< +/guid> </item> </channel>

I see that xmlns:dc="http://purl.org/dc/elements/1.1/" is missing from the RSS element.

Perhaps I have to add the namespace

If so, how do I add it for RSS 2.0, not 1.0? The module seems to accept both legitimate DC elements as well as random stuff when making objects but does not print them.

Edit:

I've also tried,

my $rss = XML::RSS->new (version => '2.0', 'xmlns:dc'=>"http://purl.org/dc/elements/1.1/ +", );

and

my $rss = XML::RSS->new (version => '2.0', namespaces => { 'xmlns:dc'=>"http://purl.org/ +dc/elements/1.1/" }, );

Neither produce any visible changes, even using Data::Dumper.

  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:

  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
