module Mobility
module Backend
=begin
Stores translations as serialized attributes in a single text column. This
implies that the translated values are not searchable, and thus this backend is
not recommended unless specific constraints prevent use of other solutions.
To use this backend, ensure that the model table has a text column on its table
with the same name as the translated attribute.
==Backend Options
===+format+
Format for serialization. Either +:yaml+ (default) or +:json+.
