Reference excerpt

The Publishing Requirements for Industry Standard Metadata (PRISM) for the Internet, computing, and computer science, is a specification that 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 assigned to PRISM specific namespaces.

Overview PRISM consists of three specifications. The PRISM Specification, itself, provides a 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 provide a simple, flexible model for transmitting content and PRISM metadata. The third, and newest, specification provides an XML schema (XSD) for the 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.

Background In 1999, Idealliance contracted Linda Burman to found the PRISM Working Group to address emerging publisher requirements for a metadata standard to facilitate “agile” content for search, digital asset management, content aggregation. Since that time, individuals from more than 50 Idealliance member companies have participated in the development of the specifications. PRISM is an Idealliance specification but is available free of charge. Idealliance (International Digital Enterprise Alliance) is a not-for-profit membership organization. Its mission is to advance user-driven, cross-industry solutions for all publishing and content-related processes by developing standards, fostering business alliances, and identifying best practices. Many organizations use PRISM because it provides a common metadata standard across platforms, media types and business units. Organizations who are involved in any type of content creation, categorization, management, aggregation and distribution, both commercially and within intranet and extranet frameworks can use the PRISM standards. The PRISM Working Group is open to all Idealliance members and includes: Adobe Systems, Hachette Filipacchi Media, Hearst, L.A. Burman Associates, LexisNexis, The McGraw-Hill Companies, Reader's Digest, Source Interlink Media Companies, Time Inc., The Nature Publishing Group, and U.S. News & World Report.

Usage and Applications PRISM can be incorporated into other standards and at this time, the PRISM Working Group is only aware of PRISM incorporation with RSS 1.0. See RSS 1.0 and the RSS 1.0 PRISM Module for more information. 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. PRISM describes many components of print, online, mobile, and multimedia content including the following:

Who created, contributed to, and owns the rights to the content? What locations, organizations, topics, people, and/or events it covers, the media it contains, and under what conditions it may be reproduced? When it was published? (cover date, post date, volume, number), withdrawn? Where it can be republished, and the original platform on which it appeared? How it can be reused? Common PRISM Usage

Syndication to partners Content aggregation Content repurposing Resource discovery and search optimization Multiple platform and channel distribution Content archiving Capture rights usage information Creation of feeds, such as RSS Standalone services Embedded descriptions, such as XMP Web publishing

Worked examples

Example 1 — a first encounter with Publishing Requirements for Industry Standard Metadata

Start with the simplest possible case. Write down what Publishing Requirements for Industry Standard Metadata claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Publishing Requirements for Industry Standard Metadata before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Publishing Requirements for Industry Standard Metadata ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Publishing Requirements for Industry Standard Metadata

In research: Publishing Requirements for Industry Standard Metadata appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Publishing Requirements for Industry Standard Metadata in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Publishing Requirements for Industry Standard Metadata is common in secondary-school and first-year university syllabi. It links to neighbouring topics Semantic Web, XML, so understanding it makes those chapters shorter.
In everyday life: Look for Publishing Requirements for Industry Standard Metadata outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
