Status

Proposed

This RSS 1.0 module has [not yet] been reviewed by the IDEAlliance PRISM Working Group and reflects the current PRISM specification, version 2.0. It is intended that revised versions of this module will be published as the PRISM specification is upgraded.

This module allows RSS 1.0 newsfeeds to make use of the basic PRISM metadata vocabulary.

Description

The Publishing Requirements for Industry Standard Metadata (PRISM) specification defines a standard for interoperable content description, interchange, and reuse in both traditional and electronic publishing contexts. PRISM recommends the use of certain existing standards, such as XML, RDF, the Dublin Core, and various ISO specifications for locations, languages, and date/time formats. Beyond those recommendations, it defines a small number of XML namespaces and controlled vocabularies of values, in order to meet the goals listed above.

The PRISM working group, a joint effort of representatives from publishers and vendors in an initiative organized under IDEAlliance, prepared the PRISM specifications.

The PRISM RSS 1.0 module augments the RSS core and Dublin Core module's metadata with channel and item-level elements specific to PRISM-based sites.

Namespace Declarations

The PRISM namespace depends on the version of PRISM that is being used:

Note that the current version is v2.0 with Errata (July 2008).

Model

<channel>, <item>, <image>, and <textinput> Elements:

This section lists each of the elements used in all versions of the basic PRISM vocabulary together with a content model for that element. For ready reference the table below shows each of the PRISM elements and the versions in which that element appears, together with the subsection numbers for the relevant versions.

The latest version in which a PRISM element appears is indicated in the listing by the version number given in brackets. For a definitive description of element usage, however, the reader should consult the relevant PRISM specifications.
