Best Practices

1. The «hasPart» element should be used in describing a collection of individual resources. Thus, a collection-level GEM record can contain multiple «hasPart» elements with each describing (i.e., 'value string') or identifying (i.e., 'value URI') an individual entity in that collection.
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.

      <dcterms:hasPart>
      Lesson Plan 2: Advanced Pythagorean Theorem
      </dcterms:hasPart>
  </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#'
