Understanding traits using score ID (d_sid)

[Michael_Wills]

Hi there,

I am trying to understand a trait (123456) that has been implemented in our instance of Audience Manager.

I believe the trait is populating based on a call being made to https://example-company.demdex.net/event?d_sid=123456, when someone signs into our intranet environment, therefore making the trait population essentially "staff". I've confirmed this request is being made by inspecting chrome developer tools (network tab) while accessing our intranet.

I noticed in Adobe Audience Manager however, the trait expression is   pixel == "staff"  for trait 123456. What is the role of this expression and what do 'pixel' and 'staff' mean? There was no additional payload/parameters with the above request to demdex, so I am unsure what the purpose of this expression is.

Any help would be greatly appreciated.

Hi @Michael_Wills 

There are two ways of Trait qualification

1) Qualification via Key:value Pair or Signal (in your case it is pixel==staff)

2) Direct Trait Id qualification irrespective of its rule or signal (in your case it is d_sid=123456)

From your statement it seems like you are directly qualifying for a Trait Id (d_sid=123456) instead of Trait rule (pixel==staff) therefore in your case the Trait definition can be anything either "pixel==staff" or "a==b" it doesn't matter because the  https://example-company.demdex.net/event?d_sid=123456 call is directly qualifying the Trait Id 123456.

You can check internally with your team who have created this Trait. It seems like they are using this signal as an identifier for their internal use only.

Do let me know if that helps

Thanks

Hey @Praupadh - thanks for your reply.

So if I understand correctly, there are two possible methods for trait qualification as per your post... and if I have a trait with expression pixel==staff (which may be a signal), the trait will qualify if either the expression is satisfied OR if a call to demdex is made?

Hi @Michael_Wills 

Yes, Your understanding is correct here, the Trait will qualify if either the expression (pixel==staff) is satisfied or the Trait id (d_sid) is itself present in the demdex call (https://example-company.demdex.net/event?d_sid=123456)
