Some documents represent a snapshot at the current time.
Some documents represents a snapshot at some particular time.

The former may require runtime resolution of links, but the latter
can well use hardcoded links (i.e. the named result of some 
previous query.)   

I  am not sure we need to deem that hardcoded links are good and 
queries are bad, or vice versa, if the question is really just one
of timing.
