I was thinking the same as Michael (using a mechanism akin to the common
use of rdfs:seeAlso), and then describe the nature of the page linked to.
Perhaps seeing it as a variant of a Linkset, to use VoID terminology [1].
Giving us something like:

    </markus> a schema:Person ;
        rdfs:seeAlso </markus/friends/page/1> .    # or something like
:describedBy (as an inverse of :about)

    </markus/friends/page/1> a void:Linkset;    # or e.g. :LinkPage
        void:linkPredicate :knows .    #  ...

(The difference to VoID is that this is reasonably occurring within the
same dataset, just partitioned across various documents
(pages/records/named graphs/information resources/...).)

Cheers,
Niklas
