Use Symfony components to map incoming JSON onto objects. Those provide a mapping. They can then be used to fetch the data in a common way and insert it into the system. - Handle languages within JsonDecode (normalize incoming data based on language) - Handle Single Value and List of Values within Entities. They will map incoming Data to proper Objects. (We now generally transform during serialization process if target is array but we got single entity) - Add missing tests for existing data. - Finish migration of all existing data, this includes next step - Provide discriminator to ObjectNormalizer to auto detect target class based on "type" property. (Done for now by own registry) - Combine generated object with current structure for import -> generate data array out of it. - Resolve foreign references to existing entities, (images, contentresponsible, etc.)
