Interest group attributes

[abrik0131]

It would be useful if there was a generic mechanism allowing advertisers to associate (attribute_name, value) pairs with interest groups on device. This information can then be used in the on-device auction.

A particular use-case is a user visiting a specific page on an advertiser's website. While in principle it is possible to implement this functionality by appending attribute-value pairs to interest group names, such an approach does not conceptually correspond well to the use-case of making an interest-group request where the reply depends on the attributes and their values.

Closing this issue as it represents past design discussion that predates more recent proposals. I believe some of this feedback was incorporated into the Protected Audience (formerly known as FLEDGE) proposal's userBiddingSignals. If you feel further discussion is needed, please feel free to reopen this issue or file a new issue.
