Element Semantics (Definition)

The described resource is a physical or logical part of the referenced resource.

General

• Label:  Is Part Of
• Namespace:  http://purl.org/dc/terms/
• Registration Authority:  Dublin Core Metadata Initiative (DCMI)
• Notes:  None

Best Practices

1. The «isPartOf» element should be used to reference a resource of which the resource being described is a part.
2. For example:
   • The resource referenced in the «isPartOf» element is a collection-level record (e.g., a collection of lesson plans) and the resource being described is a member of that collection (i.e., a single lesson plan).
   • The resource being described is a chapter in a book and the «isPartOf» element contains a reference to a record for the book itself.
3. GEM discourages the use of simple textual descriptions of the related resource (i.e., a 'value string') and instead encourages the use of a 'value URI'--i.e., a URIref that can provide a direct link to the related resource.

Metadata Encodings Examples

• Resource Description Framework (RDF/XML)
  

  Example #1 (using a 'value string'):
  
  <?xml version='1.0' encoding='UTF-8'?>
  <rdf:RDF xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#'
      xmlns:dcterms='http://purl.org/dc/terms/'>
  <rdf:Description>
      <dcterms:isPartOf>
      This is the second lesson in the "Living Things" unit.
      </dcterms:isPartOf>
  </rdf:Description>
  </rdf:RDF>
  
  Example #2 (using a 'value URI'):
  
  <?xml version='1.0' encoding='UTF-8'?>
  <rdf:RDF xmlns:rdf='http://www.w3.org/1999/02/22-rdf-syntax-ns#'
      xmlns:dcterms='http://purl.org/dc/terms/'>
  <rdf:Description>
      <dcterms:isPartOf rdf:resource='http://www.beaconlearningcenter.com/LivingThings/'/>
  </rdf:Description>
  </rdf:RDF>
  

• XML (Tags & Attributes)
  

  Example #1 (using a 'value string'):
  
  <?xml version='1.0' encoding='UTF-8'?>
  <record xmlns:dcterms='http://purl.org/dc/terms/'>
  <dcterms:isPartOf>
      This is the second lesson in the "Living Things" unit.  
  </dcterms:isPartOf>
  </record>
  
  Example #2 (using a 'value URI'):
  
  <?xml version='1.0' encoding='UTF-8'?>
  <record xmlns:dcterms='http://purl.org/dc/terms/'
      xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'>
