Developing Feeds with RSS and Atom

Name

mod_prism

Synopsis

The mod_prism module allows an RSS 1.0 feed to express metadata terms formalized by the PRISM initiative of IDEAlliance, a publisher and information technology forum. PRISM stands for Publishers Requirements for Industry Standard Metadata and aims to describe content assets from trade serial publications for syndication. PRISM defines a small set of vocabularies that work together to address industry requirements for resource discovery. Adopting the Dublin Core vocabulary (with certain qualifications), PRISM defines an additional basic vocabulary of some 50 terms, plus three smaller, more specialized vocabularies for dealing with rights, inline markup, and controlled vocabularies. This module defines the basic PRISM vocabulary and is frequently used together with the Dublin Core module.

It should be noted that this description of the mod_prism was kindly written by Tony Hammond, a coauthor of the specification itself. Many thanks to him.

Namespace

mod_prism is identified by the prefix prism: and the URI http://prismstandard.org/namespaces/1.2/basic/. Because PRISM uses Dublin Core, it is common practice (though by no means required) to see both the PRISM and Dublin Core namespaces declared together. So, the root element typically appears as:

<rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#"
         xmlns="http://purl.org/rss/1.0/"
         xmlns:dc="http://purl.org/dc/elements/1.1/"
         xmlns:prism="http://prismstandard.org/namespaces/1.2/basic/"
