FREN 3560 Digital Gallery Project (Guenther): Metadata

What is metadata?

It's data about data.  More specifically, metadata is a vocabulary that consists of elements or tags that are used to describe a variety of materials including: books, web pages, journal articles, data sets, images, digital exhibitions, and physical objects.

Examples of everyday metadata:

  • tagging photos in Facebook or Flickr
  • naming MS Word files
  • giving a title to a Youtube video
  • library catalog record

Omeka uses the Dublin Core metadata standard.  See the box at right for core elements.

 

What are the core elements in Dublin Core?

There are many potential elements that can be used in Dublin Core.  Here are the 15 basic elements that we as an institution suggest you use whenever possible (at least use the highlighted elements):

  • Title
    • name of the resource
  • Creator
    • entity primarily responsible for the creation of the resource
  • Subject
    • topic of the resource
  • Description
    • account of the resource
    • e.g. summary, table of contents
  • Publisher
    • who/what made the resource available
  • Contributor
    • who/what made contributions to the resource
    • someone who contributed a file an Omeka project or who donated a collection
  • Date
    • date when the original resource was created, not the digitized version
    • If you can find a date on the resource, use it - if not, simply enter n.d.
  • Type
    • the nature or genre of the resource
    • use these itemtypes from Omeka: Document, Moving Image, Oral History, Sound, Still Image, Website, Event, Email, Lesson Plan, Hyperlink, Person, or Interactive Resource
  • Format
    • physical medium, file format, or dimensions of a resource
  • Identifier

    • this should be the title of the original source
  • Language
    • language of the resource
  • Relation
    • a related resource
    • e.g. separate issues from a particular series
  • Coverage
    • usually the spatial or temporal topic
    • e.g. postcard - does it depict a location or a time period?
