The term relationshipOfResource has the recommendation to use a controlled
vocabulary. The vocabulary does not yet exist - it is an aspect that
requires community development. The ResourceRelationship class has the added
benefits over the associatedOccurrences term that there is no dependence on
the syntax of the content to discern the correct meaning.

>>>From http://rs.tdwg.org/dwc/terms/index.htm#relationshipOfResource:

Definition: The relationship of the resource identified by relatedResourceID
to the subject (optionally identified by the resourceID). Recommended best
practice is to use a controlled vocabulary.

Comment: Examples: "duplicate of", "mother of", "endoparasite of", "host
to", "sibling of", "valid synonym of", "located within". For discussion see
