Dear all, Erik is totally right, there will be some cases where ordering is server-driven, so we should support both alternatives. I'm not happy with Nandana's proposal, since I would prefer not injecting protocol triples into resource descriptions. In the example, ordering information is represented in the page and not in the container or in its members. I think that the current proposal is complementary to Richard's one. In the example, only the description of the page should be changed: <http://e.org/nw1/assets/?firstPage> a ldp:Page; ldp:pageOf <http://e.org/nw1/assets/>; ldp:order (<http://e.org/nw1/assets/a2> <http://e.org/nw1/assets/a1> <http://e.org/nw1/assets/a3>). Servers could specify ordering in one way, the other, or both.
