  1. Lifecycle Metadata for Digital Objects Danielle Cunniff Plumer School of Information The University of Texas at Austin Summer 2014

  2. Class Introductions • Identify • Yourself • Types of digital projects you have worked on or are interested in • Your role in these digital projects • Your experience with metadata

  3. Metadata • “Metadata is structured information that describes, explains, locates, or otherwise makes it easier to retrieve, use, or manage an information resource.” • Key Concepts: • Structured information • Ease of use • Formal standards Source:NISO. (2004) Understanding Metadata.Bethesda, MD: NISO Press, p.1

  4. Functions of Metadata • List:

  5. Metadata • A good object has associated metadata. • A good object will have descriptive and administrative metadata, and compound objects will have structural metadata to document the relationships between components of the object and ensure proper presentation and use of the components. Source:NISO. (2007). “Objects Principle 6” in A Framework of Guidance for Building Good Digital Collections. Bethesda, MD: NISO Press.

  6. Types of Metadata • Descriptive • Structural • Administrative • Technical • Rights Management • Preservation Source:NISO. (2004) Understanding Metadata.Bethesda, MD: NISO Press, p.1

  7. Metadata Standards • Interoperability and object exchange require the use of established standards • Semantic: Content Standards • Syntactic: Metadata Schemas • Format: Machine encoding • Exchange: Interface protocols • XML is a common method for exchanging metadata descriptions on the Internet • Others include: JSON, RDF

  8. Metadata Components Human Machine

  9. Insert Joke about Standards "Fortunately, the charging one has been solved now that we've all standardized on mini-USB. Or is it micro-USB? Shit." http://xkcd.com/927/

  12. Plan of Course: Assignments

  13. Questions?

  14. Using Metadata • Description • To (more or less) uniquely identifyan item • To identify the parts of an item and their relationship to the whole Author Davis, Ellis A. Title The encyclopedia of Texas, compiled and edited by Ellis A. Davis and Edwin H. Grobe. Imprint Dallas, Texas Development Bureau [1922?]

  15. Using Metadata • Location • To show where to find the item • Call number • Archival container • Storage unit • Uniform Resource Indicator Library: UNT Libraries Location: WILLIS 4FL TEXANA COLL Identifier: 976.4 D292t  V. 1

  16. Using Metadata • Condition • To document the condition of an item at a given time • To record any actions taken with respect to the item’s condition Binding: Full-Leather Book Condition: Fair Jacket Condition: No Jacket

  17. Using Metadata • Use • To explain conditions of use for an item • Based on condition • Based on rights Status: LIB USE ONLY Rights: Public Domain based on publication date of 1922.

  18. Digital is Different • Does the metadata describe the physical item or the digital item, or both? • Physical item • Metadata as “surrogate” for the physical item • Metadata for inventory of and access to the physical item • Metadata aggregated for use in “union catalogs” • Digital item • Metadata as a component of the digital object itself • Metadata used as a way of pointing to the digital object from metadata aggregations

  19. Metadata and Digital Objects • Metadata can be: • In the digital object • File headers, e.g., TIFF, EXIF; EAD, TEI headers • Near the digital object • Same directory, hard drive, network • Thousands of miles from the digital object • On another network, in another state, in another country

  24. Identifiers as Metadata • A good object will be named with a persistent, globally unique identifier that can be resolved to the current address of the object. • Good identifiers will at minimum be locally unique, so that resources within the digital collection or repository can be unambiguously distinguished from each other. • Global uniqueness can then be achieved through the addition of a globally unique prefix element, such as a code representing the organization. Source:NISO. (2007). “Objects Principle 4” in A Framework of Guidance for Building Good Digital Collections. Bethesda, MD: NISO Press.

  25. Identifiers in Metadata • The description of a digital object must be specific enough to distinguish it from similar objects • Unique identifiers make this easier • The link between a digital object and its metadata must exist and be maintained over the entire lifespan of the object • Persistent identifiers are essential

  26. Exercise: Physical & Digital • Break into groups • Choose one of the objects listed (view online) • http://goo.gl/BpkS1U • For each object, create two records: • Surrogate record for the physical object in a library, museum, or archives. • Metadata record for the digitized object available online. • Describe the differences between the two records
