Hi, I've started doing a survey of various SPARQL extensions. The survey is going to be in two parts. The first will look at SPARQL extension functions, i.e. extensible value testing. The second will look at property functions (aka magic predicates, etc). My overall goal is to try and pull together lists of the various functions to help promote some cross-pollination and convergence. I'm hoping the SPARQL WG might find this useful. I've made a first pass at a review of the extension functions. You can look at the info here: http://spreadsheets.google.com/pub?key=tl2FDWghDKDc3G70xKkNoNg&output=html I've put it into a spreadsheet initially for my own convenience but will publish it somewhere else once its completed. If you have know of any engines that support either extension functions or property functions then please drop me a mail. Similarly if you think I've made any mistakes or omissions then please feel free to correct me. Its entirely possible I've overlooked something (its late! ;) Cheers, L. -- Leigh Dodds Programme Manager, Talis Platform Talis leigh.dodds@talis.com http://www.talis.comReceived on Tuesday, 6 October 2009 20:11:30 GMT
