associatedOccurrences Identifier: http://rs.tdwg.org/dwc/terms/associatedOccurrences Class: http://rs.tdwg.org/dwc/terms/Occurrence Definition: A list (concatenated and separated) of identifiers of other Occurrence records and their associations to this Occurrence. Comment: Example: "sibling of FMNH:Mammal:1234; sibling of FMNH:Mammal:1235". For discussion see http://code.google.com/p/darwincore/wiki/Occurrence Details: associatedOccurrences
My questions: a. Are the names of the associations, and/or the syntax of the value meant to be community defined? b. If no to a. , where are those definitions? If yes, Have any communities defined any names and syntax? I am especially interested in "duplicate of" in the case of herbarium sheets." c. (May share an answer with b.) Is there any use being made by anyone in which associatedOccurrences is designed to have machine-readable values. If yes, where?
Thanks Bob
