mod_DCTerms

Synopsis

Once Dublin Core metadata has sunk its I-must-add-metadata-to-everything addictive nature into your very soul, you soon realize that the core terms are lacking in depth. For example, dc:relation means “is related to,” but in what way? We don’t know, unless we use mod_DCTerms.

mod_DCTerms introduces 28 new subelements to channel , item, image, and textinput, as appropriate. These subelements are related, within Dublin Core, to the core elements found within mod_dublincore, but mod_DCTerms does not express this relationship. For example, dcterms:created is actually a refinement of dc:date.

Namespace

mod_DCTerms takes the namespace prefix dcterms: and is identified by the URI http://purl.org/dc/terms/. So, the root element looks like this:

<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" 
         xmlns="http://purl.org/rss/1.0/"
         xmlns:dcterms="http://purl.org/dc/terms/"
>

Elements

You have a lot to choose from with this module. As we’ve said, the elements can be subelements of channel, item, image, or textinput. Apply liberally and with gusto.

dcterms:alternative

An alternative title for the item. For example:

<title>Programming Perl</title>
<dc:title>Programming Perl</dc:title>
<dcterms:alternative>The Camel Book</dcterms:alternative>
dcterms:created

The date the object was created, in W3CDTF standard (YYYY-MM-DDTHH:MM:SS).

dcterms:issued

The date the object was first made available. This should be used, for backward compatibility, with ...
