 Below we describe the JSON schema for the **func_stats**, **counter_stats** and **ad_model** collections of the **global database** component of the provenance database.
 
+A common data structure **RunStats** is used extensively to represent statistics (mean, min/max, std. dev., etc) of some quantity. It has the following schema:
+
+|      {
+|        **'accumulate'**: *The sum of all values (same as mean \* count). In some cases this entry is not populated*,
+|        **'count'**: *The number of values*,
