[Mediawiki-l] semarbtri help request

[Kelly Jones]

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
