There seems to be a bit of confusion over what RDFa can and can't do as well as the current state of the art. We have created an RDFa Firefox plugin called Fuzzbot (for Windows, Linux and Mac OS X) that is a very rough demonstration of how an browser-based RDFa processor might operate. If you're new to RDFa, you can use it to edit and debug RDFa pages in order to get a better sense of how RDFa works. There is a primer[1] to the semantic web and an RDFa basics[2] tutorial on YouTube for the completely un-initiated. The rdfa.info wiki[3] has further information. ---------------- (sent to public-r...@w3.org earlier this week): We've just released a new version of Fuzzbot[4], this time with packages for all major platforms, which we're going to be using at the upcoming RDFa workshop at the Web Directions North 2009 conference[5]. Fuzzbot uses librdfa as the RDFa processing back-end and can display triples extracted from webpages via the Firefox UI. It is currently most useful when debugging RDFa web page triples. We use it to ensure that the RDFa web pages that we are editing are generating the expected triples - it is part of our suite of Firefox web development plug-ins. There are three versions of the Firefox XPI: Windows XP/Vista (i386) http://rdfa.digitalbazaar.com/fuzzbot/download/fuzzbot-windows.xpi Mac OS X (i386) http://rdfa.digitalbazaar.com/fuzzbot/download/fuzzbot-macosx-i386.xpi Linux (i386) - you must have xulrunner-1.9 installed http://rdfa.digitalbazaar.com/fuzzbot/download/fuzzbot-linux.xpi There is also very preliminary support for the Audio RDF and Video RDF vocabularies, demos of which can be found on YouTube[6][7]. To try it out on the Audio RDF vocab, install the plugin, then click on the Fuzzbot icon at the bottom of the Firefox window (in the status bar): http://bitmunk.com/media/6566872 There should be a number of triples that show up in the frame at the bottom of the screen as well as a music note icon that shows up in the Firefox 3 AwesomeBar. To try out the Video RDF vocab, do the same at this URL: http://rdfa.digitalbazaar.com/fuzzbot/demo/video.html Please report any installation or run-time issues (such as the plug-in not working on your platform) to me, or on the librdfa bugs page: http://rdfa.digitalbazaar.com/librdfa/trac -- manu [1] http://www.youtube.com/watch?v=OGg8A2zfWKg [2] http://www.youtube.com/watch?v=ldl0m-5zLz4 [3] http://rdfa.info/wiki [4] http://rdfa.digitalbazaar.com/fuzzbot/ [5] http://north.webdirections.org/ [6] http://www.youtube.com/watch?v=oPWNgZ4peuI [7] http://www.youtube.com/watch?v=PVGD9HQloDI -- Manu Sporny President/CEO - Digital Bazaar, Inc. blog: Fibers are the Future: Scaling Past 100K Concurrent Requests http://blog.digitalbazaar.com/2008/10/21/scaling-webservices-part-2
