Metadata for Digital Content

Jane Mandelbaum, Ann Della Porta,

Rebecca Guenther


Charge
Charge

  • Recommend one common set of metadata elements for all digital content

  • Analyze existing descriptive metadata

  • Recommend methods for creation of metadata for existing digital objects that lack metadata


Why do we need this
Why do we need this?

  • Provide access to LC’s digital content which may be stored in separate environments

  • Share the content and the metadata

  • Provide additional services to users, e.g., Web 2.0 functions

  • Improve LC’s Metasearch service


Building on existing foundation
Building on Existing Foundation

  • Metadata schemas from various digital projects (e.g. American Memory, Performing Arts Encyclopedia, Web capture)

  • Search requirements and use cases are to be supported

  • WDL search and discovery vision – metadata elements and presentation options

  • Relationship (if any) to ILS records needs to be understood


Use cases
Use Cases

  • Concrete examples of “what we could do if we have better metadata”

  • Examples:

  • Navigation by place, date, type of item, topic

  • Reuse for different audiences, in different combinations and delivery mechanisms

  • Better access to the content in web pages


Doing something useful next steps
Doing Something Useful: Next Steps

  • Search and Discovery

    • Improve Data for Faceted Searching

    • Add More Content for Federated Searching

    • Migrate Towards More Access Points for External Search Engines


Doing something useful next steps1
Doing Something Useful: Next Steps

  • Targeted Improvements

    • Create standardized metadata for videos for internal use and external providers

    • More options for presentation and delivery

    • Access to more content in LC web pages


How are we doing it
How are we doing it?

  • Establish a master set of metadata elements commonly used among digital projects

  • Annotate the list with preferred practices for metadata content

  • Create metadata profiles for each initiative, detailing which elements are used and how they are encoded

  • Identify where metadata remediation is needed and attempt to improve existing records


Lc metadata profiles
LC metadata profiles

  • American Memory

  • Performing Arts Encyclopedia

  • LC Web pages

  • LC Web Archives

  • National Digital Newspaper Program

  • World Digital Library

  • LC Webcasts

  • LC Exhibits

Future goals
Future goals

  • Use the metadata profile for newly described digital content so that there is consistency

  • Use common rules for metadata content

  • Remediate existing metadata where possible

  • Establish a common search interface to provide seamless access to LC digital content


Metadata remediation geographic
Metadata remediation: geographic

  • Best practices

    • Supply hierarchical form

    • Prefer controlled form

  • Remediating existing data

    • Translate coded form into controlled textual form for presentation

    • Translate uncontrolled form into controlled form

    • Translate into hierarchical form (e.g. Country—State—City)

    • Extract geographic subdivisions from subject strings and make searchable

    • Extract state information
