51. 4.1. Title Label: Title Element Description: The name given to the resource. Typically, a Title will be a name by which the resource is formally known. Guidelines for creation of content: If in doubt about what constitutes the title, repeat the Title element and include the variants in second and subsequent Title iterations. If the item is in HTML, view the source document and make sure that the title identified in the title header (if any) is also included as a Title. Examples: Title="A Pilot's Guide to Aircraft Insurance" Title="The Sound of Music" Title="Green on Greens" Title="AOPA's Tips on Buying Used Aircraft" Entry Guidelines for Dublin Core Element #1: Title Source: http://dublincore.org/documents/usageguide/elements.shtml
52. 4.2. Subject Label: Subject and Keywords Element Description: The topic of the content of the resource. Typically, a Subject will be expressed as keywords or key phrases or classification codes that describe the topic of the resource. Recommended best practice is to select a value from a controlled vocabulary or formal classification scheme. Guidelines for creation of content: Select subject keywords from the Title or Description information, or from within a text resource. […] In general, choose the most significant and unique words for keywords, avoiding those too general to describe a particular item. Subject might include classification data if it is available (for example, Library of Congress Classification Numbers or Dewey Decimal numbers) or controlled vocabularies (such as Medical Subject Headings or Art and Architecture Thesaurus descriptors) as well as keywords. […] Examples: Subject="Aircraft leasing and renting" Subject="Dogs" Subject="Olympic skiing" Subject="Street, Picabo" Source: http://dublincore.org/documents/usageguide/elements.shtml Entry Guidelines for Dublin Core Element #3: Subject

What is Metadata? Structuring Metadata Metadata in Practice Going to crash through a bunch of stuff tonight, but just a few main points: structured data makes good and important things possible. HIST 678 - METADATA LECTURE: J. RILEY 2/23/11

Structured and standardized. Data = structured information.. Structure + Standards = the key! What are some other examples of structured data? telephone book shopping catalog iTunes library… HIST 678 - METADATA LECTURE: J. RILEY 2/23/11
You could read that first line as “Describing a resource with additional structured, standardized information…” HIST 678 - METADATA LECTURE: J. RILEY 2/23/11
What are the benefits of iTunes metadata? Allows resources to be found, identified, described, annotated, collocated, shared and disambiguated - go through each one of these re/how iTunes makes that possible. Found: can search – “Journey” the band vs “Journey” in a song title Identified HIST 678 - METADATA LECTURE: J. RILEY 2/23/11

iTunes chose to include certain fields. The set of fields it chose were ok, but lacking in some ways and users often find them confusing or lacking. Various communities of practice – archivists, professional photographers, scientists, videographers – have settled on their own sets of fields that they want to use to describe the resources that they create and use. These sets of fields are arrived at after long discussions and require institutional heft, and communication and getting everyone on board. But once they’re on board, you have a SCHEMA, or structural standard. HIST 678 - METADATA LECTURE: J. RILEY 2/23/11

This is true of ALL of schemas – elements are defined for you, guidelines and tools are available. HIST 678 - METADATA LECTURE: J. RILEY 2/23/11
Do these fields seem that they would be able to describe most cultural heritage objects? HIST 678 - METADATA LECTURE: J. RILEY 2/23/11
