Apps like Mail and TextEdit can recognise commonly used bits of information in your text: a physical address, a phone number, a date and time, etc. With a click, you can send that information into the appropriate program, like Calendar, Contacts, or your Web browser (for looking up an address on a map). This is what the DataDetectorsActionService is used for.

Awesome. Thank you. Was wondering myself. Should such a thing show up in Settings - Security and Privacy - Privacy - Location Services? It looks a little unprofessional for Apple.
