2D sexpressions for GIS, Frank/Nile

Has anyone considered GIS sexpressions for Frank/Nile/Open Croquet/Cobalt?
First one would be given a map with capabilities, one could place
sexpressions on a map on points in areas,  like (deposit (sell (bottle
(ferment (harvest #grapes #harvest-location-capability)) #wente-riesling))
#bank-of-america-account-capability).  Perhaps I am thinking of simfarm but
with sexpressions for learning programming and commerce.  Perhaps I'll do
some googling if no one has anything.  Perhaps this is a kind of 2D SHRDLU.
