I'd be tempted to generalise or just remove the domain/range
restrictions. Any thoughts?
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.
