@Transactional
public class ContentDaoImpl<C extends ContentDescriber>

Default JPA implementation for ContentDao with support by the default Transaction Manager
TODO: All locale based code is based on AbstractContent.getLocale().Language. Country & variant are currently practically null and place-holders in the object. In the future respect them in DB queries for extended Locale and region based support for content.
