owl - SWRL: restrict a rule to a specific individual -

-

lets there class "food" containing individuals "grain" , "fruit" . if want select grain can assign food_type data property individuals 

(class) food     (ind_1) grain   food_type ---> "grain_food"     (ind_2) fruit   food_type ---> "fruit_food"

and run code:

  food(?x) ^ food_type(?x,"grain_food") -> sqwrl:select(?x)

but if want job (select grain individual) without needing food_type property? possible directly point specific individual name?

it's not clear you're asking, yes, can use individual in swrl rule. e.g., if have individual c class c, can do:

    c(c) ⟶ sqwrl:select(c)

as long sqwrl:select doesn't require variable (i.e., long can accept individual directly), should fine. if requires variable, opposed individual directly (which go against intent, think), guess use kind of equality predicate, swrbl:equal:

    swrlb:equal(c,?x) ⟶ sqwrl:select(?x)
