MicroTurtle, the sloppy RDF format: http://buzzword.org.uk/2009/microturtle/spec That's very interesting. I like it, but I'm not sure that it's necessarily what I would ideally like if I were coming to RDF afresh. It looks like the perl of RDF syntaxes :) Which is good for some people, but not others. Something like NTriples + UTF-8 + @prefix could be an answer for people new to RDF. One of the problems is the various triple shortcut syntaxes we use. Either the stacked syntax of RDF/XML, or the punctuation of Turtle. For anyone who's about to say that Turtle = ntriples + UTF-8 + @prefix - it doesn't help. The vast Majority of examples you see online use at least ; and probably [] and , too, which makes it very hard to follow. At least in my experience of introducing developers to RDF. FWIW my experience with technically savvy but non-semweb people is that Turtle is a not only a low barrier it is a selling feature in a way that abbreviated n-triples isn't. I've people who are using RDF solely because they find Turtle a more convenient, compact notation for writing down their data than any of the (mostly XML based) alternatives they've tried. The fact that you can use a similar notation in queries has helped too. Dave -- Hewlett-Packard Limited Registered Office: Cain Road, Bracknell, Berks RG12 1HN Registered No: 690597 England

Nice!

Re: Excellent News for LOD: Yahoo Provides Tool for RDFa+GoodRelations for Site Owners
Well at first blush this is good news. But then why do we want to use a vocabulary like product:listPrice which is locked to a specific yahoo domain: http://search.yahoo.com/searchmonkey/product/ ? Is Google going to come along with another different word for that? Then which one does a catalog owner choose? Re this example from the referenced page: div typeof=product:Product xmlns:product=http://search.yahoo.com/searchmonkey/product/; xmlns:rdfs=http://www.w3.org/2000/01/rdf-schema#; span property=product:listPrice27.99/span span property=product:currency content=USD / span property=rdfs:labelStartech Serial ATA Cable - 45.72cm - Red/span /div -- Seth Russell www.speaktomecatalog.com On Thu, Jul 9, 2009 at 8:24 AM, Martin Hepp (UniBW) martin.h...@ebusiness-unibw.org wrote: Dear all: Great news: ANY site owner in the world has now a clear incentive to add GoodRelations meta-data in RDFa to his/her page: As of now, Yahoo will display price and offering details and other meta-data of any e-commerce Web page if the site owner uses GoodRelations vocabulary elements.
