The PRISM specification defines a set of metadata vocabularies. PRISM metadata may be expressed in a different syntax depending on the specific use-case scenario. Currently PRISM metadata can be encoded XML, XML/RDF, or as XMP. Each of these expressions of PRISM metadata is called a profile. • Profile 1 is for the expression of PRISM metadata in XML. An example is the XML PRISM Aggregator Message (PAM). • Profile 2 is for the expression of PRISM metadata in XML/RDF such as for expressing PRISM metadata in RSS feeds. • Profile 3 is for embedding PRISM metadata in media objects such as digital images or PDFs using XMP technology. No matter which profile is used, the PRISM metadata fields and values remain constant. The expression of PRISM metadata for each profile is documented within the PRISM Specification.
