Element Semantics (Definition)

A reference to a resource from which the present resource is derived.

General

• Name:  source
• Label:  Source
• Namespace:  http://purl.org/dc/elements/1.1/
• Registration Authority:  Dublin Core Metadata Initiative (DCMI)
• Notes:  The present resource may be derived from the Source resource in whole or in part. Recommended best practice is to reference the resource by means of a string or number conforming to a formal identification system.

Best Practices

1. In GEM, the use of the «source» element is discouraged. The preferred mechanism for making statements about an entity from which the resource being described was derived is to use the «isDerivedFrom» element (a refinement of the «relation» element).
2. The source can be represented using a 'value string' (e.g., the literal name of the source) or by means of a 'value URI' (a machine-addressable identifier of the source).

Metadata Encodings Examples

• Resource Description Framework (RDF/XML)
  

  Example #1 (using 'value string'):
  
  <?xml version='1.0' encoding='UTF-8'?>
  <rdf:RDF xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#'
      xmlns:dc='http://purl.org/dc/elements/1.1/'>
  <rdf:Description>
      <dc:source>
      Gone with the Wind
      </dc:source>
  </rdf:Description>
  </rdf:RDF>
  
  Example #2 (using 'value URI'):
  
  <?xml version='1.0' encoding='UTF-8'?>
  <rdf:RDF xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#'
      xmlns:dc='http://purl.org/dc/elements/1.1/'>
  <rdf:Description>
      <dc:source rdf:resource='http://www.GoneWithTheWind.html'/>
  </rdf:Description>
  </rdf:RDF>
  

• XML (Tags & Attributes)
  

  Example #1 (using a 'value string'):
  
  <?xml version='1.0' encoding='UTF-8'?>
  <record xmlns:dc='http://purl.org/dc/elements/1.1/'>
  <dc:source>
      Gone with the Wind.
  </dc:source>
  </record>
  
  Example #2 (using a 'value URI'):
  
  <?xml version='1.0' encoding='UTF-8'?>
  <record xmlns:dc="http://purl.org/dc/elements/1.1/"
      xmlns:dcterms='http://purl.org/dc/terms/' 
      xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
  <dc:source xsi:type='dcterms:URI'>
      http://www.GoneWithTheWind.html
  </dc:source>
  </record>
