### Data Profile Annotation
-The data profile annotations count the instances of each type and the counts of the elements attached to them. This is illustrated in figure 6.
+This discovery service attaches multiple data profile annotations to each data field depending on their category (entity, relationship, classification or business metadata).

+It sets up the following fields in each data profile annotation:
+
+* *analysisStep* - this is always set to "PROFILE".
+* *annotationType* - this identifies the type of values that the annotation contains.
+* *explanation* - this provides more information about the annotation type.
+* *valueCount* - this is a map of typeName to count. For example, if this annotation was counting the classifications attached to the *DataSet* entity type, then the map would include an entry for each type of classification attached to this type of entity and a count of how many times it is used.
+* *additionalProperties* - contains the count of instances for the particular type that the data field represents.
+
+The table summarizes the values in each of the data profile annotations depending on the category of the data field it is attached to.
