There are lots of uses for rand and domain.

One is in the user interface -- if you for example link a a person and  
a document, the system
can prompt you for a relationship which will include "is author of"  
and "made" but won't include foaf:knows or is issue of.

Similarly, when making a friend, one can us autocompletion on labels  
which the current session knows about and simplify it by for example  
removing all documents from a list of candidate foaf:knows friends.

It is of course also important for checking hand-written files for  
validity.
