ontologies OF programs

Reading Daniel Dennett’s “From Bacteria to Bach and Back” this morning, I came across an interesting section where he extends the notion of ontology—a “system of things that can be known”—to programs. Specifically, he writes about what kinds of things a GPS program might know about: latitudes, longitudes, etc.

I was struck by the connection to the “data definition” part of the design recipe. Specifically, would it help beginning programmers to think about “the kinds of data that their program ‘knows about’”? This personification of programs can be seen as anti-analytical, but it might help students a lot.

Perhaps I’ll try it out this fall and see how it goes.

Okay, that’s all.
