Excellent, why didn't I think of that? I stand corrected.

I'll go you one better.  English has the copula ("am"), which is lacking in
many natural languages.  So we can read <> as analogous to the "sum" of
"Cogito ergo sum".  And since <> is general, we can take it as referring
not just to identity but to space-time location, yielding <> =
sum-here-now.  Then if we discard the notion that RDF triples must be
translatable directly or naturally to Subject-Verb-Object constructions in
some natural language, we can write

<> <> <> .

At least I think we can.  I'm not sure how best to gloss it; something like
"every doc is related to itself by itself (in space-time)"?  Which is kinda
sorta like "I am", if you squint hard enough.

It won't get published in Philosphical Quarterly any time soon, but it
makes for a pretty good RDF riddle.
