In fairness, Markus was providing an alternative to the Turtle which was given earlier in the message stream. I think, given the subject of this list, that some people may be more comfortable with JSON-LD, and it may better reflect actual message content, as it's not always clear what the HTTP body boundaries are with Turtle. My original Turtle follows:

</collection> a hydra:PagedCollection;
 hydra:member <1>, <2>, ...;
 hydra:nextPage </collection?page=2>;
 hydra:pageOf </collection#dataset> .
<collection#dataset> a hydra:Collection;
 hydra:totalItems 243;
 hydra:itemsPerPage 10;
 hydra:firstPage </collection>;
 hydra:lastPage </collection?page=24> .

While I also prefer Turtle when talking about the model, I can't say I really see how the JSON-LD obscures the ER semantics, given the properties used in the Hydra vocabulary are implicit in this conversation.
