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.
