In other situations, in the absence of any other obvious predicate with that directionality, one must use odrl:target instead.

Looking at that specific example, there are a couple of ways that you could do it, but I'd personally probably do...
<http://example.com/policy:881212>
a policies:Set ;
odrl:permission [
odrl:action actions:index ;
odrl:target <http://example.com/archive/2010> ;
x:collection <http://example.com/x/database> .
] .
I think it's fairly reasonable to say that the reverse-direction relation (i.e., where we use dct:rights or dct:license) only unambiguously applies where it would be the target of *all* permissions and prohibitions which constitute the policy (you could be cleverer about it, but the axiom of diminishing returns applies given the additional burdens it places upon consumers of the data).
