The whole thing actually reminds me of Inform7, which is a natural language implementation of text adventures on a similar (albeit very old) database query language system.
I just wrote a tiny parser game in Inform, and the language is fascinating. You can create complex, fully interactive scenes in just a few sentences. For example, with just "There is a billiards table in the Gazebo. On it is a trophy cup. A starter pistol is in the cup." Inform would create three objects (a billiards table, a trophy cup and a starter pistol) in a previously established room (the Gazebo), and would deduce that the billiards table is a supporter (you can put things on it) and the trophy cup is a container (you can put things in it). With no further code you can examine all three items, remove the pistol from the cup and put it on the table, and so on.
