I picked on the hash since that was your example - what appeared to be a User record. Yes, you can save anything you want, it's only yaml after all...
So the :summary_data from your example maps on to a series of name<>value tuples. Other languages refer to this as marshalling, I seem to recall that Ruby has some functions with marshall in their name. Rails likes to talk about serializing and attribute lists, ActiveRecord provides the attributes method as an easy way to serialize the record's fields.
