This analysis compares element usage in the 18 NASA collection with the 8 non NASA (Other) collections. The bubble chart below This evaluation identifies elements which exist in collections as well as elements that are complete in collections. In order for an element to exist in a collection it must be present in at least 1 metadata record included in the collection. In order for an element to be complete in a collection it must be present in all metadata records included in the collection.
Chart 1 below compares element existence in NASA Collections with Other collections. The X axis shows elements that exist in NASA collections.
The X axis shows the number of NASA collections that include an element. The Y axis shows number of Other collections that include an element. The bubble size shows the number of elements included in the bubble. The large blue bubble in the upper right corner of the plot includes elements that exist is all 18 NASA collections and in all 8 Other collections. This bubble includes 51 elements, as referenced in the legend.
