Publishing Requirements for Industry Standard Metadata : ウィキペディア英語版 | Publishing Requirements for Industry Standard Metadata
The Publishing Requirements for Industry Standard Metadata (PRISM)〔(PRISM Metadata Standard )〕 specification defines a set of XML metadata vocabularies for syndicating, aggregating, post-processing and multi-purposing content. PRISM provides a framework for the interchange and preservation of content and metadata, a collection of elements to describe that content, and a set of controlled vocabularies listing the values for those elements. PRISM can be XML, RDF/XML, or XMP and incorporates Dublin Core elements. PRISM can be thought of as a set of XML tags used to contain the metadata of articles and even tag article content. PRISM conforms to the World Wide Web standard for Namespaces. PRISM namespaces are PRISM (prism:), PRISM Usage Rights (pur:), Dublin Core (dc: and dcterms:), PRISM Inline Metadata (pim:), PRISM Rights Language (prl:), PRISM Aggregator Message (pam:), and PRISM Controlled Vocabulary (pcv:). PRISM incorporated existing industry standards such as Dublin Core and XHTML in order to leverage work that had already been done in the publishing industry. New elements were created only when required, and were assigned to PRISM specific namespaces. == Overview == PRISM consists of three specifications. The PRISM Specification, itself, provides definition for the overall PRISM framework. A second specification, the PRISM Aggregator Message (PAM) Schema/DTD, is a standard format for publishers to use for delivery of content to websites, aggregators, and syndicators. PAM is available as an XML DTD and an XML schema (XSD). Both PAM formats provides a simple, flexible model for transmitting content and PRISM metadata. The third, and newest, specification provides an XML schema (XSD) for capture of content usage rights metadata. This Guide to PRISM Usage Rights utilizes the elements found in PRISM’s Usage Rights Namespace to allow users to comprehensively capture and relay rights metadata for text and media content.
