Hi,

This is now updated with extension functions from Sesame, Mulgara and
TopQuadrant:

http://spreadsheets.google.com/pub?key=tl2FDWghDKDc3G70xKkNoNg&output=html

Remaining are to add some additional bif functions from Virtuoso and
1-2 additional ones I've overlooked in ARQ.

Not sure what to do yet about ARC which allows any MySQL function
(that passes the parsing rules, to be used in a query) that'd be a
long list to add to the spreadsheet :) Might be more useful to try and
find out which ones people are using.

Cheers,

L.
