Elements complete in no IDN Collections and some NASA Collections

Sixty-three elements are complete in no IDN Collections and some NASA Collections. These are the bubbles on the X axis in the chart. None are complete in more than nine NASA collections. Many of these elements are related to keyword thesaurus and additional attribute information. It is interesting to note that keyword thesaurus information is completely absent from the IDN collections, reflecting the fact that GCMD keywords are used in those collections, perhaps as a requirement of participation in the IDN.
