The Inform 7 interactive fiction system parses human readable English assertions and builds an interactive system from your statements. I have only played with it briefly, but take the following example:
"Test" by Jason The Foyer is a room. The crate is in the Foyer. The crate is a Container. The player is in the crate. The crate is closed. The crate is openable. The latch is in the crate. The latch is fixed in place.
