MY DEFINITION 5

• Data is the core communication of a piece of content.

• Metadata is information about the content that provides
structure, context and meaning.


TYPES OF METADATA 9

• Structural Metadata
• Models the content types and attributes

• Administrative Metadata
• Indicates how, when and by whom the content was created
• Defines how it can and will be used, its status, who can access it

• Descriptive Metadata
• Describes the subject matter of the content

EXAMPLE METADATA 10

Title: Ta-dah!
Description: That’s a serious jello mold!
Tags: jello, layers, delicious

EXERCISE 15

Group Discussion: How is Metadata used?


HOW METADATA IS USED 23

• Search
• Browse
• Contextual Linking
• Aggregation
• Syndication
• Access Permissions
• Personalized Content
• Advanced Functionality


CREATING STRUCTURAL METADATA 26

Start with the Content Management System

1. Determine the content types.

2. Determine the elements that make up each type.

3. Determine any potential relationships between content types.


CONTENT MANAGEMENT SYSTEMS 27

Separate the information from
the presentation


DETERMINE THE CONTENT TYPES 28

• Which types of content are different enough that they might
warrant a unique structure and/or layout?
• Article, quiz, slideshow, recipe and event are all fairly distinct.

DETERMINE THE ELEMENTS OF EACH TYPE 29

• Figure out the separate elements, or attributes, of each one.
• Think about how each segment of information will be used.
• EX: Event

Event Name

Date & Time

Location

Event © Barnes & Noble

DETERMINE RELATIONSHIPS BETWEEN TYPES 30

• Content can be linked or embedded within another item.
• EX: The book & author each have their own page

Book Page

Author Page

Event © Barnes & Noble

EXERCISE 31

Individual Task:

• Identify the content
attributes & relationships
in a recipe

Recipe © Food Network

STRUCTURAL METADATA: RECIPE 32

Content Attributes:
• Title
• Author
• Tags
• Time
• Level
• Yield
• Ingredients
• Directions


STRUCTURAL METADATA: RECIPE 33

Relationships:
• Show
• Episode
• Photo
• Sub-Recipes
• Glossary Terms
• Related Guides/Menus
• Recipes Like This


CREATING ADMINISTRATIVE
METADATA

CREATING ADMINISTRATIVE METADATA 35

Consider how the content is used, published, and delivered.

1. Identify functionality driven by administrative aspects of the
content.

2. Determine preferred formats for administrative attributes.

Note: Administrative metadata tends to be used a lot more in digital records of offline
material, so you’ll see it utilized a lot in library and archive work.


CONSIDERATIONS 36

• Where did the content come from?
• Are there restrictions on how it can be used?
• Is the content time-sensitive or evergreen?
• Who can access it?
• When it’s archived or indexed, how will it be ordered?
• Does the content have to adhere to any legal regulations?


IDENTIFY FUNCTIONALITY 37

Dynamic functionality based on the status, date, permissions, or other
administrative aspects of the content.


DETERMINE FORMATS & VALUES 38

• Text Field
• Numbers
• DateTime
• Can appear in a variety of formats, for example:
- YYYY-MM-DDThh:mm:ss[.mmm]
- 2012-03-01T11:00:00

• Boolean
• True or False
• Selection List

Note: In order to reliably sort or filter content by administrative data, use the appropriate
format so that the data can be compared in a meaningful way.

EXERCISE 39

Group Discussion: What kinds of functionality would be
supported by the following Administrative Metadata?

• Publish date
• Status
• Source
• Author
• Version
• Copyright


CREATING DESCRIPTIVE METADATA 41

What is the content is about?

1. Determine the high level dimensions.

2. Determine the level of depth needed to support functionality.

3. Fill out the details in each dimension.

Note:There are a lot of things that can be described about any give content.To constrain
the scope, the aspects that are being described should also be based on data that’s needed
to drive functionality.


IDENTIFY FUNCTIONALITY 42

Dynamic functionality based on descriptive aspects of content.

SOURCING VOCABULARIES 51

Where do you get all this metadata?

• Industry Standards

• Commercial & Open Vocabularies

• Your own content


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


THREE FOUNDATIONAL STANDARDS 54

Many 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!


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


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/


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/


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/

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

RNEWS 60

• Uses RDFa to express news-specific
metadata
• Coordinated with Schema.org
• Used by the New York Times

• For more information see:
http://dev.iptc.org/rNews

Article © The Wall Street Journal

EXERCISE 61

Team 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

COMMERCIAL & OPEN
VOCABULARIES

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


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

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


FINAL EXERCISE 70

Group 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.
