I suggest to answer as follows:

rif:local is a symbol space in RIF, not a datatype. That means it 
doesn't have a particular value space or lexical-to-value mapping defined.

Given this, I am unsure about what the question means, but maybe that 
already gives an answer?

BTW: also note that RIF is not restricted to Herbrand interpretations.
