prototype

From the latest version of my paper (or, alternatively, your cell
phone camera):

There are three fundamental types of objects in the system: Things,
Triples, and Theories. A Thing is any Lisp object Elephant can
store. They are stored with the format [id|data]. A Triple
indicates three Things, by id. These are interpreted as
relationships or semantic links; so a Triple (C, A, B) says that A is
related to B by C. A Theory indexes an arbitrary collection of
Things, possibly giving each element a new ``local'' name.
Basically, however, a Theory is just a subset of the collection of
all Things (and so, a subnetwork, viewed under the relations defined
by Triples).

I'd like to modify this slightly and actually put together a
prototype. (Looks like it will be a bit of a wait for Elephant.)
Specifically, let's say the data components of Things were just
strings.

Suppose we can do this within a week in SQL? I'd like to give it a
try; if you can help with the database implementation that would be
super.
