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.
Kind regards,
