But how did Siri learn who Scott’s wife was? The demo didn’t show us, but I have a suspicion about how it works. The Mac Address Book has long had an entry for setting up relationships between contacts. I can indicate who my spouse is in Address Book. I suspect that the iPhone Contacts app will gain similar new fields in iOS 5. I haven't used Siri so I don't know whether it'll use those fields, but I do know that if it didn't know who Scott's wife was, it'd have asked him and then remembered his answer. I also don't know (but would like to!) whether it does said remembering by updating the contact. Edit: seen on Twitter, "Siri doesn't just remember your mother, father, and other significant people, it adds them to your contact details." So: it's not a separate store.
