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?
