Introduction to Metadata for IDAH Fellows

  1. 1. Introduction to metadata for IDAH fellows Jenn Riley Metadata Librarian Digital Library Program
  2. 2. 12/5/2008IDAH Seminar 2 Many definitions of metadata • “Data about data” • “Structured information about an information resource of any media type or format.” (Caplan) • “Structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use, or manage an information resource.” (NISO) • …
  3. 3. 12/5/2008IDAH Seminar 3 Some uses of metadata • By information specialists ▫ Describing “non-traditional” materials ▫ Cataloging Web sites ▫ Navigating within digital objects ▫ Managing digital objects over the long term • By novices ▫ Preparing Web sites for search engines ▫ Depositing materials into an institutional repository ▫ Managing citation lists ▫ iTunes ▫ Tagging – flickr, del.icio.us, etc. ▫ LibraryThing
  4. 4. Good metadata… • Meets a defined purpose • Conforms to accepted standards and/or best practices • Doesn’t have to be created by humans 12/5/2008 4 IDAH Seminar
  5. 5. Metadata formats • Predefined sets of features likely to be necessary or useful for a specific purpose • Choosing a format others also use improves interoperability • Can be: ▫ Official standards ▫ Backed by professional organization ▫ Backed by trusted institution ▫ Locally developed 12/5/2008 5 IDAH Seminar
  6. 6. 12/5/2008IDAH Seminar 6 Creating metadata • HTML <meta> tags • Spreadsheets • Databases • XML • Library catalogs • Digital library/content management systems
  7. 7. Some types of metadata • Descriptive metadata • Technical metadata • Structural metadata • Markup languages 12/5/2008 7 IDAH Seminar
  8. 8. How metadata is used 12/5/2008IDAH Seminar 8
  9. 9. Descriptive metadata • A description of a resource • For discovery ▫ Includes both search and browse ▫ In a controlled environment designed to match target users with interesting resources ▫ Pushed out to the network for others to make use of • For display ▫ Gives a user the context they need to understand a resource • Can be both objective and subjective • Usually human-generated 12/5/2008 9 IDAH Seminar

  15. 15. Structural metadata • Describes relationships ▫ Points of interest within a resource ▫ Between parts and wholes ▫ Between different representations of the same content ▫ When resources should be presented in sequence ▫ When resources should be presented in parallel • Often machine generated 12/5/2008 15 IDAH Seminar
