MicroTurtle, the sloppy RDF format:

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.

Nice!

And it seems to work for just the HTML+RDFa snippet generated by
ReDeFer RDF2HTML:

 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.

 Previously, such data was only used within special applications
 developed in the Yahoo ecosystem. Now, every site owner can add
 meta-data to enhance the search results of offers in Yahoo.

 Just go to

 http://developer.search.yahoo.com/help/objects/product

 and click on the tab RDFa - GoodRelation.

 The tool generates mark-up patterns for copy-and paste into xhtml page
 content.

 Thanks to Peter Mika and everybody at Yahoo for this initiative! It will
 for sure help lower the entrance barrier for any business to use
 Semantic Web technology in general and GoodRelations in particular.

Re: Excellent News for LOD: Yahoo Provides Tool for RDFa+GoodRelations for Site Owners

2009-07-13 Thread Seth Russell
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
