I have noticed that some annotators have been using the role :duration for cases like the one below. I think that :age is more appropriate, even for non-biological entities.
In a sense, :age is a special case of :duration ("duration of existence to date").
In particular, unlike :duration, :age includes the notion that the temporal-quantity of its entity keeps increasing as it continues to age.
"They lobbied Congress to repeal the 15-year-old law."
