Labeling Example

Sample Hit Data

Suppose you have the following hit data:

  • The first row contains the labels for each variable.
  • The second row is the name of the variable. If it has an ID label, it contains the assigned namespace in parentheses.
  • Hit data starts in the third row.
Labels I2
ID-PERSON
DEL-PERSON
ACC-PERSON		 I2
ID-DEVICE
DEL-DEVICE
ACC-ALL		 I2
DEL-PERSON
ACC-PERSON		 I2
DEL-DEVICE
DEL-PERSON
ACC-ALL		 I2
ID-DEVICE

Variable Name

(user)		 Visitor ID
(AAID)		 MyEvar1 MyEvar2 MyEvar3
(xyz)

Sample Access Request

If I submit an access request, the summary file will contain the values indicated in the table below. A request may return only a device file, only a person file or one of each. Two summary files are only returned if a person ID is used and expandIds is true.

user=Mary false person Mary 77, 88, 99 A, B, C M, N, O X, Y, Z
user=Mary true person Mary 77, 88, 99 A, B, C M, N, O X, Y, Z
user=Mary true device not present 77, 88 not present N, P U, W
user=Mary AAID=66 true person Mary 77, 88, 99 A, B, C M, N, O X, Y, Z
user=Mary AAID=66 true device not present 66, 77, 88 not present N, P U, W, Z
xyz=X false device not present 55, 77 not present M, R X
xyz=X true device not present 55, 77 not present M, P, R W, X

Notice that the setting for expandIDs does not make any difference to the output when a cookie ID is used.

Sample Delete Request

With a delete request using the API values in the first row of the table, the hit table will be updated to look something like this:

AAID=77 expandIDs value
does not matter		 AAID=77 expandIDs value
does not matter		 AAID=77 expandIDs value
does not matter		 AAID=77 expandIDs value
does not matter		 AAID=77 expandIDs value
does not matter
MyProp1 AAID MyEvar1 MyEvar2 MyEvar3
Mary 42 A Privacy-7398 Privacy-9152
Mary 88 B N Y
Mary 99 C O Z
John 42 D Privacy-1866 Privacy-8216
John 88 E N U
John 44 F Q V
John 55 G R X
Alice 66 A N W
NOTE

Only cells on rows containing AAID = 77 and a DEL-DEVICE label are impacted.

user=Mary
expandIDs=false		 user=Mary
expandIDs=false		 user=Mary
expandIDs=false		 user=Mary
expandIDs=false		 user=Mary
expandIDs=false
MyProp1 AAID MyEvar1 MyEvar2 MyEvar3
Privacy-0523 77 Privacy-1866 Privacy-3681 X
Privacy-0523 88 Privacy-2178 Privacy-1975 Y
Privacy-0523 99 Privacy-9045 Privacy-2864 Z
John 77 D P W
John 88 E N U
John 44 F Q V
John 55 G R X
Alice 66 A N W
NOTE

Only cells on rows containing user=Mary and a DEL-PERSON label are impacted. Also, in practice the variable containing A_ID would probably be a prop or eVar and its replacement value would be a string starting with “Privacy-”, followed by a random number (GUID), rather than replacing the numeric value with a different, random numeric value.

user=Mary
expandIDs=true		 user=Mary
expandIDs=true		 user=Mary
expandIDs=true		 user=Mary
expandIDs=true		 user=Mary
expandIDs=true
MyProp1 AAID MyEvar1 MyEvar2 MyEvar3
Privacy-5782 09 Privacy-0859 Privacy-8183 Privacy-9152
Privacy-5782 16 Privacy-6104 Privacy-2911 Privacy-6821
Privacy-5782 83 Privacy-2714 Privacy-0219 Privacy-4395
John 09 D Privacy-8454 Privacy-8216
John 16 E Privacy-2911 Privacy-2930
John 44 F Q V
John 55 G R X
Alice 66 A N W

Note the following:

  • Cells on rows containing user=Mary and a DEL-DEVICE or DEL-PERSON label are impacted, as well as cells with a DEL-DEVICE label on rows containing any Visitor ID that occurred on a row containing user=Mary.
  • MyEvar2 in the fourth and fifth rows is updated because these rows contain the same Visitor ID values as those on the first and second rows, so ID expansion includes them for device-level deletes.
  • The values of MyEvar2 in rows two and five match both before and after the delete, but after the delete no longer matches the value N that occurs in the last row, because that row was not updated as part of the delete request.
  • MyEvar3 behaves very differently than it did without ID expansion, because without ID expansion, no ID-DEVICES matched. Now AAID matches on the first five rows.
