Element Semantics (Definition)

The resource being described is higher in some arbitrary hierarchy than the resource being pointed to by this Relation element. See also «isChildOf»

General

• Name:  hasChild
• Label:  Has Child
• Namespace:  http://purl.org/gem/qualifiers/
• Registration Authority:  GEM Consortium
• Notes:  None

Best Practices

1. The «hasChild» element should be used to reference a hierarchical child of the resource being described.
2. 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)
  

  RDF Example:  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:gemq='http://purl.org/gem/qualifiers/'>
  <rdf:Description>
      <gemq:hasChild>
      [@@@@]
      </gemq:hasChild>
  </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:gemq='http://purl.org/gem/qualifiers/'>
  <rdf:Description>
      <gemq:hasChild rdf:resource='@@@@'/>
  </rdf:Description>
  </rdf:RDF>
  

• XML (Tags & Attributes)
  

  Example #1 (using a 'value string'):
  
  <?xml version='1.0' encoding='UTF-8'?>
  <record xmlns:gemq='http://purl.org/gem/qualifiers/'>
  <gemq:hasChild>
      @@@@  
  </gemq:hasChild>
  </record>
  
  Example #2 (using a 'value URI'):
  
  <?xml version='1.0' encoding='UTF-8'?>
  <record xmlns:gemq='http://purl.org/gem/qualifiers/'
      xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance'
      xmlns:dcterms='http://purl.org/dc/terms/'>
  <gemq:hasChild xsi:type='dcterms:URI'>
      @@@@
  </gemq:hasChild>
  </record>
