handle filtering submitted content
https://github.com/liip/LiipVieBundle/ had optional integration of the DMS Filter library. we should do something about this again. maybe the right place would be in the Midgard\CreatePHP\RdfMapperInterface implementations. we would need "something" to configure how to filter each field.
comment from https://github.com/liip/LiipVieBundle/pull/20 by flack was:
filtering could be configured with the normal createphp type setup and then passed along as config options to the rdfMapper, so transporting this information via createphp wouldn't require any serious code changes. For validation, see my other comment. This needs some sort of support from create.js, since it should normally be handled by the client side, with server validation as fallback only (and of course ideally powered by the same configuration)
maybe we should have a listener on doctrine that does filter everything that gets persisted. we have the same problem with sonata admin.
