Projects Using Dublin Core

The Book's Land Digital Library Catalog Electronic Visualization Library EULER (European Libraries and Electronic

Resources in Mathematical Sciences) Gathering the Jewels MALVINE: Manuscripts and Letters via

Integrated Networks in Europe The European Library

Advantages

Simplified nature Least common denominator database Function in databases which utilize various

kinds of metadata Unifying metadata

Cost Flexibility

http://www.loc.gov/marc/marc2dc.html

http://www.loc.gov/marc/dccross.html

Disadvantages

Slow establishment of basic guidelines. Elements not given clear definition.

Example: Creator or Contributor, Source or Relation?

Uses vary for each element Multiple versions of a source.

Example: images: physical vs. digital; who is the creator of which?
