 * Decouples the client from the server.
 * Clients may not want ALL the fields.

-* This client isn't used to form links, to no need to implement the `Identifiable<T>` interface.
 * This client isn't used to fashion test data (yet), so no need for special constructors.
 
 All in all, it's enough to give it the empty constructor so Jackson can handle serializing/deserializing data over the wire.

 NOTE: Make your REST resources robust by instructing Jackson to ignore unknown attributes. That way, additional elements,
 like hypermedia (HAL *_links*, HAL-Forms *_templates*, etc.) and newer attributes will be discarded.
