PRISM (Publishing Requirements
for Industry Standard Metadata)

PRISM is an IDEAlliance Specification that defines an XML metadata fields and controlled vocabularies for managing, aggregating, and delivering publishing content for magazines, journals and more. . .

The PRISM Working Group initiated its work in 1999, released PRISM 1.0 in 2001 and addressed publishing across media platforms by releasing PRISM 2.0 in 2008. Today PRISM Specifications serve as the foundation for two XML Tagging Schemas:

PRISM Aggregator Message: An XML tag set developed in 2004, designed to package articles for delivery to content aggregators. PAM is built on PRISM metadata fields and XHTML for encoding text.
PRISM Source Vocabulary: An XML tag set developed in 2011, designed to encode a wide variety of content, from articles, to advertisements to the chapters of books. PSV is built upon PRISM 3.0 metadata and HTML5 for encoding text and rich media content.
