    @RelatedTo(type = "likes", direction = OUTGOING)
    public Set<Beverage> likesBeverages;

    public Person() {

                  final Set<Restaurant> likesRestaurants,
                  final Set<Beverage> likesBeverages) {
        this.name = name;
        this.likesRestaurants = likesRestaurants;
        this.likesBeverages = likesBeverages;
