   A setup can look as follows:

positive.code: 
  `ResourceMetaProvider` exposes all JSON API resources and repositories as meta data. You may add further provides to
  expose more meta data, such as the `JpaMetaProvider`.
  
  To learn more about the set of available resources, have a look at the `MetaElement` class and all its subclasses. Some of the
  most important classes are:

  ### Identifiers for Meta Elements
  
  Of importance is the assignment of IDs to meta elements. For resources the resource type is used to compute the meta
  id and a `resources` prefix is added. In the example above, person gets a `resources.person` meta id.
  Related objects (DTOs, links/meta info) located in the same or a subpackage of a resource gets the same meta id prefix.
