Well! Quite a bit of success with our test deployment of a SPARQL server. The server runs at http://biodiversity.org.au/sparql/. I have a very nice html page that uses the JSON output, but WordPress won’t let me upload it. Oh well. And, of course, our wiki is locked up. Oh well. Here’s code for a simple HTML form. WordPress clips it, but that’s just display: you can still c/p it into a html file.
