Thanks to everyone who replied. Answers to questions:
% I originally tried to integrate this into Semantic MediaWiki, but
the code there seems very "page-centric". There doesn't seem to be a
concept of an arbitrary tuple. I'm sure this could be integrated into
Semantic MediaWiki (and since both are open source, anyone is welcome
to try), but I found it easier to write something separate. I'd
definitely like to get a lot of Semantic MediaWiki's features, either
by merging it into my code or vica versa.
% If you put [[x::R::y]] on page z: S Page is correct. You can edit
the tuple on page z only. It will be displayed read-only on both pages
x and y. However, the display on x and y will tell you that z created
the tuple, so you know where to go to edit it.
% I'd really like to get the table data looking nicer (eg, using
Exhibits), though I'd prefer something more server-side than
client-side (not sure JSON/JavaScript is that universally supported
browser-side?)
% I'd like to get a little more done (in terms of bug fixes +
formatting) before "officially" announcing this at
http://www.mediawiki.org/wiki/Extension_Matrix

Suppose I put [[x::r::y]] on a page. Does it appear
on page x? On page
y? Can I edit it in either of those places? What happens if I do?

I've now created a test site for a semantic

put the triple (x,R,y) anywhere, not just on page x:
http://semarbtri.kgprog.com/wiki/index.php/Main_Page
The code is available:
http://semarbtri.kgprog.com/SemArbTri.txt
The syntax for a triple is "[[x::R::y]]" (or just "[[R::y]]" if
you're
already on page x).
Broken things I'd like help with:
% When editing an existing page, all the semantic info vanishes. Compare:
http://semarbtri.kgprog.com/wiki/index.php/The_Light_Fantastic
The first page has semantic info, the second doesn't. My extension
does have a "in edit mode, don't display semantic data" comment + some
supporting code, but commenting out this code doesn't help.
% When editing a new page, semantic info is visible, but unformatted:
http://semarbtri.kgprog.com/wiki/index.php?title=Wizard&action=edit
% If I try to protect against spammers by adding this to
LocalSettings.php:
