We are currently implementing Audience Studio, one piece needed in our project is a first-party import. My initial thought for this was to use a data extract activity in the marketing cloud to do this as a daily job. I am trying to figure out if the Data Extract activity can be manipulated to model the data needed to work with SF Audience Studio. Here is an example of how the data needs to be structured:
User1234^gender:male;age:18-24;interest:fishing
User2345^gender:female
User3456^age:35-44
User4567^gender:male;interest:fishing,boating
Any help would be appreciated! Hopefully, as the products become more integrated this will be a native feature.
