Introduction • Benefits of Dublin Core Metadata Element Set • Dublin Core Elementsand Qualifiers • Uses of DC Outside the Library • Guidelines for DC Metadata Creation
Benefits of Dublin Core (DC) What is Dublin Core?Metadata standard of 15 elements, used for describing and cataloging electronic resources. Result of 1995 workshop by Online Computer Library Center (OCLC) in Dublin, Ohio. Benefits? • Elements are optional. • Elements are repeatable. • Elements allow qualifiers for refinement. • DC can describe all types of resources, including new electronic and digital data types. • DC can cover descriptive, structural and administrative metadata.
DUBLIN CORE ELEMENTS Content Elements • Title • Subject • Description • Type • Source • Relation • Coverage Intellectual Property Elements • Creator • Publisher • Contributor • Rights Instantiation Elements • Date • Format • Identifier • Language Additional Elements • Audience • Provenance • RightsHolder
Dublin Core qualifiers can add refinement and granularity to element descriptions. Like elements, qualifiers are optional and repeatable. This DC record includes qualifiers for Identifier, Description, and Subject elements. Dublin Core Record with Qualifiers
Using DC: Example The Walters Islamic Manuscript Digital Project Walters Art Museum, Baltimore Md. Digitization project of art and calligraphy, 9-19th century 2 Metadata Entry Steps • Before digitization:Preliminary metadata entered into web-based database • After digitization:Cataloger adds more information. Authors, artists, scribes, dates, materials, languages, keywords…
Using DC: Example Digital Video Repositories • Ball State University Libraries’ Digital Media Repository:Ball State’s video collection, includes commencement speeches, WWII films. Descriptive records mapped into Dublin Core.http://libx.bsu.edu • Folkstreams.net:documentary films of American folk culture. Mapped into Dublin Core.http://www.folkstreams.net • Shannon County Film: original rolls of documentary film footage. MARC to Dublin Core crosswalk.http://library.missouristate.edu/projects/scf/index.html
Using DC: Example Digital Video Repositories (continued) • Australian Center for the Moving Image (ACMI):Collections of film, television, video clips – used at lending library, theater screenings, student filmmakers’ work. Metadata records described directly with Dublin Core.http://www.acmi.net.au • NJVid (New Jersey Digital Video Repository):Centralized video portal from educational institutions in NJ. Record descriptions in Dublin Core, MARC, and MODS.http://www.njvid.net • Windows on Maine: Streaming videos on history of Maine. Union catalog, MARC to Dublin Core Crosswalk.http://windowsonmaine.library.umaine.edu
Using DC: Example Dspace Dspace is an open source digital asset management tool used worldwide by institutions “including public and private colleges and universities and a variety of non-profit corporations.” (Kurtz, 2009)http://www.dspace.org Dublin Core’s elements and qualifiers are central to Dspace.
Guidelines for DC Metadata Creation Guideline #1: “Resource description should beas complete as possible.” Try your best to fill as much detail as you can, see what can be supplied that can’t be found when examining the resource. Leave element blank as a last resort. Guideline #2: “Resource description should be consistent.” Consistency helps human users with information retrieval, reduces cognitive overload. Use controlled values when possible. Coleman, 2005, p. 157
