Tables that include "Exists" in their titles give the average number of times that the metadata items (elements or attributes) occur per metadata record.

• Cells with numbers > 1.0 indicate elements that typically (although not necessarily) occur one or more times in each record in a collection.
• Cells with numbers = 1.0 indicate elements that typically occur once per record.
• Cells with number < 1 indicate elements that occur less than once per record and are, therfore, not included in all records in the collection. This value is typically the percentage of records in a collection that include the metadata element. 
• Cells with number = 0 and pink backgrounds indicate items that do not occur in any records in a collection.

The Tables that include "Complete" in their titles give the average number of occurrences of UMM-Collection elements in each of these collections. A value of 1 or more typically (although not necessarily) indicates that the element is included one or more times in each record in a collection.  A value < 1.0 Cells with pink backgrounds indicate values of 0, meaning the element is completely missing from the collection% of records in a collection that include a metadata item. These values range from 0 (completely missing) to 1.0 (in all records) and do not provide information about how may times the item occurs.
