The effect of multiple inheritance can be achieved by using modules.

First define the ActiveRecord objects like this:

class Topic < ActiveRecord::Base; end
class Location < ActiveRecord::Base; end

There is no longer a base Tag abstract class, allowing Tag to be defined as a module like this (app/concepts/tag/crud.rb):

module Tag
