We need to think of a way to query a remote collection to determine whether it contains an item without downloading the whole thing. This could be useful in a number of different ways — like getting an authoritative response on whether a wall post was accepted, or whether someone is someone else’s friend.

SPARQL?
LDP lightly mentions Sparql in 5.1.1.
Sorting/ordering is also kind of relevant to querying, see LDP-Paging.

This is another proposed way of querying: Linked Data Fragments | Concept

• e.g. query for the triple “[container] [ldp:contains] [item]”
