MIKROKOSMOS

Produce and manufacture are two common predicate heads in the business domain. Agent and theme are common slots for these heads--someone or some company "makes" something.

Another common type of text includes the number of items produced or the rate at which items are produced/manufactured. For this, there is a rate slot. An example of how it is used:

;; Acme Co. produced 30000 tons of steel this year.

%produce_1
    agent	%company_1
		    name	"Acme Co."
    theme       %steel_1
    [...]
    rate	%rate_1
			unit	    *ton
 			interval    *year
                        quantity    *30000

Note that the rate slot works just as well for other types of units and intervals (weeks, etc.).
