Here is an example of using Dublin Core to describe a Dublin Core description of the Web version of Ariadne:

Notes:

• The frist RDF:Description is taken from example AP2 (slightly simplified) and describes the Web version of Ariadne.
• The second RDF:Description describes the first. It asserts that the first set of metadata was written by Andy Powell on 7th March 1998.
• The third RDF:Description is an example only. It is an RDF representation of the following vCard:

  BEGIN:vCard
  FN:Andy Powell
  ORG:University of Bath;UK Office for Library and Information Networking
  ADR;TYPE=work:;;;Bath;;BA2 7AY;United Kingdom
  TEL;TYPE=work,voice:+44-1225-323933
  EMAIL;TYPE=internet:a.powell@ukoln.ac.uk
  URL:http://www.ukoln.ac.uk/ukoln/staff/a.powell.html
  END:vCard
