Adding new integrators

• The Sword engine has an integrator to work with Hyrax. This resides in app/controllers/concerns/integrator/hyrax.

• This integrator is loaded from app/controllers/concerns/willow_sword/integrator

• To add a new integrator, add functionality similar to the hyrax integrator and override app/controllers/concerns/willow_sword/integrator in your local rails app, to load your new integrator.
