Note:
This analysis compares element usage in 17 NASA 2016 collection with element usage in 18 2017 collections. This evaluation identifies elements which exist in collections. In order for an elements to exist in a collection it must be present in at least 1 metadata record included in the collection. Element usage for NASA 2016 collections and NASA 2017 collections is shown below using bubble charts. The bubble chart interpretation graphic provides a schematic for interpreting the bubble plots.
Bubble Chart Interpretation
Chart 1 below compares element existence in 2016 NASA Collections with 2017 NASA collections. The X axis shows the percent of NASA 2016 collections that include an element. The Y axis shows the percent NASA 2017 collections that include an element. The bubble size shows the number of elements included in the 2 collections.
The large red bubble in the upper left corner of the plot shows elements that exist is 100 percent of NASA 2017 collections and 0 percent of NASA 2016 collections. This bubble includes 24 elements, as shown in the legend. The large yellow bubble in the upper right corner of the plot shows elements that exist is 100 percent of NASA 2016 and 100 percent of NASA 2017 collections. This bubble includes 22 elements, as shown in the legend. The data for Chart 1 is accessible in Google Sheets. To view the data and bubble chart in Google Sheets click on the image.

To access the data for this chart, click on the chart graphic above to view an interactive version in Google Sheets. The interactive version enables data identification for each bubble and includes a look up table for identifying the ISO elements associated with the bubble. To access and use the interactive version:
Twenty-seven items (elements and attributes) are complete in all NASA and all Other Collections: See the All NASA and All Other filtered view to identify these items.
Nineteen items (elements and attributes) are complete in all Other collections and complete in a smaller number of NASA collections. See the All Other and Some NASA filtered view to identify these items.
Ted please double check this filter. The table below includes 52 items not 19
Table 2. Metadata Elements that are in all Other and in a smaller number of NASA collections
One hundred and fifteen items (elements and attributes) are complete in 0 Other collections and are complete some number of NASA collections. See the No Other and Some NASA filtered view to identify these items.
