Outline
  • Why metadata?
  • Concepts to know
  • Selected metadata standards
  • Metadata transport standards
  • Music-related efforts
  • Questions and answers

3
Metadata
  • What is metadata?
  • Data about data
  • Or Structured Data about data
  • Sound familiar?
  • Lots of communities do metadata

4
So whats the big fuss?
  • The Web is large and growing quickly
  • Many producers, many users on the Web
  • Navigating networked resources is difficult
  • Good description
  • better access
  • better control
  • Control and access big business
  • Convergence of interests collaboration in
    building standards (interoperability)

5
Concepts to know
  • Types of metadata
  • Descriptive
  • Structural
  • Administrative

  • Sharing...

Selected metadata standards
  • ISBD AACR2
  • Dublin Core (DC)
  • Text Encoding Initiative (TEI) headers
  • Encoded Archival Description (EAD)
  • VRA Core Categories (VRA CC)
  • http//www.oberlin.edu/art/vra/wc1.html
  • Content Standard for Digital Geospatial Metadata
    (CSDGM, formerly FGDC) http//www.fgdc.gov/metadat
    a/contstan.html

10
Dublin Core
  • DC (Dublin Core)
  • 15 elements for simple resource description
  • Designed to support interoperability
  • Translated into 26 languages
  • Qualifiers under ballot

Dublin Core (in HTML)

Text Encoding Initiative
  • SGML DTD designed to support literary text markup
    but has wider potential
  • TEI standard has been influenced by both scholars
    and librarians
  • TEI header (TEIH) can be used as a metadata
    object in its own right
  • EAD community is considering using TEIH for
    single item metadata records

14
Encoded Archival Description
  • SGML DTD for archival finding aids
  • Maintained by the Library of Congress
  • Allows for simple or complex mark-up to support
    varying levels of indexing
  • Well-suited for interweaving narrative with links
    to specific objects in a collection (either
    directly to the object or via a record).

Metadata transport standards
  • MARC (MAchine Readable Cataloging)
  • SGML (Standard Generalized Markup Language)
  • HTML (Hypertext Markup Language)
  • XML (Extensible Markup Language)
  • RDF (Resource Description Framework)

17
Sample of RDF-XML
RDF see http//www.w3.org/rdf
18
Music markup languages
  • HyTime (Hypermedia/Time-based Structuring
    Language)
  • SMDL (Standard Music Description Language)
  • NIFF (Notational Interchange File Format)
  • MNML (Music Notation Markup Language)
  • SMF Lyric Meta Event Definition
