  • METADATA SOURCES
  • SOURCING VOCABULARIES 51Where do you get all this metadata?• Industry Standards• Commercial & Open Vocabularies• Your own content ©2012 Razorfish. All rights reserved.
  • INDUSTRY STANDARDS
  • INDUSTRY STANDARDS 53• Provide a good starting point for structural metadata that you can build upon• Make your content more compliant with tools and APIs that also use the standards• Enable more effective Search Engine Optimization ©2012 Razorfish. All rights reserved.
  • THREE FOUNDATIONAL STANDARDS 54Many of the other standards are based on these:• RDF/RDFa – a non-hierarchical structure for expressing metadata• Dublin Core – a set of core attributes that can be used for any type of content• Schema.org – a collection of frameworks for a wide range of content types, developed by a collaboration between Google, Bing & Yahoo! ©2012 Razorfish. All rights reserved.
  • RDF: RESOURCE DESCRIPTION FRAMEWORK 55• Provides a structure (aka framework) for describing identified things (aka resources)• Composed of three basic elements • Resources – the things being described (Ex: “Men In Black”) • Properties – the relationships between things (Ex: “hasStar”) • Classes – the buckets used to group the things (Ex: “Movie”)• Elements combine to make simple statements called Triples • Men In Black is a Movie Movie Actor • Will Smith is an Actor typeOf typeOf • Men In Black stars Will Smith <MenInBlack> <hasStar> <WillSmith> Men In Black hasStar Will Smith ©2012 Razorfish. All rights reserved.
  • RDFA: RDF IN ATTRIBUTES 56• Allows RDF attributes and properties to be included in XHTML and HTML documents. <div> <div xmlns:dc="http://purl.org/dc/elements/1.1/"> <h2 property="dc:title">The trouble with Bob</h2> <h2>The trouble with Bob</h2> <h3 property="dc:creator">Alice</h3> <h3>Alice</h3> … </div>• For more information see: http://rdfa.info/ ©2012 Razorfish. All rights reserved.
  • DUBLIN CORE METADATA INITIATIVE 57• A metadata framework for describing any type of content• Example attributes: • Name: The unique term that identifies the item • Label: The human-readable label assigned to the term • Definition: A description of the term.• Example properties: • abstract: A summary of the item • audience: The intended audience for the item • creator: A person, organization or service responsible for creating the item • license: Indicates usage rights for the item • subject: The topic of the item• For more information see: http://dublincore.org/ ©2012 Razorfish. All rights reserved.
  • SCHEMA.ORG 58• A collaboration between Google, Bing and Yahoo!• Intended to improve the display of search results by directly including valuable data right• Includes formats for marking up the following common types of content (as well as many others): • Creative works (such as Books, Movies, Music, Recipes, etc.) • Non-text objects (such as Audio, Image,Video) • Events • Organizations • Persons • Places • Products & Offers • Reviews• For more information see: http://schema.org/ ©2012 Razorfish. All rights reserved.
  • STANDARDS FOR SPECIFIC TYPES OF CONTENT 59• For Journalism • PRISM = Publishing Requirements for Industry Standard Metadata • NewsML for news, news metadata, and news management metadata • rNews uses RDFa to express news-specific metadata in news content• For Images • EXIF = Exchangeable Image File Format, data embedded by digital cameras • XMP = Extensible Metadata Platform, developed by Adobe • ITPC Photo Metadata for professional news and stock photos• For Videos • MPEG-7 from the Moving Picture Experts Group, add data to audio and video • Media RSS a flavor of RSS that allows for detailed info about media• For Social Connections • FOAF = Friend of a Friend, describes people, their connections & creations • SIOC = Semantically-Interlinked Online Communities, incorporates social networks• For Products • Good Relations for E-commerce ©2012 Razorfish.

  • EXERCISE 61Team Task: Apply a standard• Determine how the properties of rNews would be applied to the sample content• Start by looking through the specification to see which properties seem likely to be applicable ©2012 Razorfish. All rights reserved. Article © The Wall Street Journal
  • COMMERCIAL & OPENVOCABULARIES
  • COMMERCIAL & OPEN VOCABULARIES 63• Provide descriptive metadata, often for a specific knowledge domain• Can hook into other data or content that may be used to augment your own• Will probably need to be expanded or modified• Commercial vocabularies may be expensive to license, but commercially supported• Open vocabularies are free to use, but may not be as well supported ©2012 Razorfish. All rights reserved.
  • USEFUL RESOURCES 64• WAND Inc – commercial taxonomies and tools• WordNet – a lexical database for English• Taxonomy Warehouse – a searchable directory of commercial and open taxonomies• Linked Data – open data sets on the web ©2012 Razorfish. All rights reserved.

  • LINKED OPEN DATA – SEPTEMBER 2011 66Diagram by Richard Cyganiak and Anja Jentzsch
  • YOUR OWN CONTENT
  • YOUR OWN CONTENT 68• Navigation, current classification and other site functionality should be leveraged as a starting point for any new metadata development• Offline resources can also provide inputs• Evaluate current site organization to make sure you’re not carrying over structures that are obsolete• Consider future functionality to make sure you have accounted for additional needs• Entity extraction tools (there are many out there) can evaluate large amounts of content and automatically generate metadata ©2012 Razorfish. All rights reserved.
  • YOUR OWN CONTENT 69 ©2012 Razorfish. All rights reserved. © NME
  • FINAL EXERCISE 70Group Discussion: Identify Sources of Metadata• Pretend you’re going to redesign nme.com• Identify possible sources of metadata you would use – including standards, commercial or open data sets, and data from the site itself. ©2012 Razorfish. All rights reserved. © NME
