recorded(?Key,
?Value, ?Reference)True if Value is recorded under Key and has the
given database Reference. If Reference is given,
this predicate is semi-deterministic. Otherwise, it must be considered
non-deterministic. If neither Reference nor Key is
given, the triples are generated as in the code snippet below.90Note
that, without a given Key, some implementations return
triples in the order defined by recorda/2
and recordz/2.
