there is a gap here, i don't see how we get from implementing a specific interface in a controller to getting the data in the sonata service. maybe a small example of how to use the sonata service would help.

but i guess this will get quite changed with https://github.com/ElectricMaxxx/CmfSeoBundle/issues/17 anyways. what remains interesting is how i could do some custom seo tweaking in my controller / some listener.
