RE: RDF/A in the wild?

That's really useful, Stephane.
We're also in the process of looking at the business case for adding RDFa to one of our sites, and I'd be really interested to hear people's experience of the impact of RDFa on traffic.

One great example is the bbc.co.uk/news site that also embeds RDFa (see http://www.bbc.co.uk/blogs/internet/posts/News-Linked-Data-Ontology for the details) - I was particularly interested to hear Jeremy Tarling say that not only did RDFa improve their click through rates (as might be expected with pretty search results, and the oft-quoted Best Buy statistic of a 30% improvement in click through), but it also pushed the BBC news pages up the Google search rankings.

Does anyone have any other hard data to support the case for RDFa? Do developers find it useful as a way of harvesting metadata?
Cheers,
Cathy

Hello,

There seems to be no activity on the more public list. I hope this is not an inappropriate question.

I probably have a fundamental misunderstanding but, where can I see RDF/A being used on a web page and resulting in the data being used to produce detailed search results in a search engine. The point being a real world actual use of RDF/A, not an example of how to use RDF/A.

A few random examples:
Event: http://www.curlingcalendar.com/tournaments/664 (Rich snippet review<http://goo.gl/HqyKox>, live search result<http://goo.gl/OXGw9N>)
Person: http://definitivedrupal.org/authors/jacine-luisi (Rich Snippet preview<http://goo.gl/ghsk8a>, live search result<http://goo.gl/Zzo3An>)
Recipe: http://abc-dieta.sk/jahody-s-tvarohovou-plnkou.html (Rich Snippet review<http://goo.gl/LJlgDz>, live search result<http://goo.gl/ci6J7C>)

(search for 'schema:' in the HTML source)



If I look on the goodrelations website, there are examples of marking up web pages with microdata or rdf/a but the pages themselves do not use microdata or rdf/a. Or, I am looking in the wrong place.

Another example, if I search for best buy, for example, in google, I see detailed search results, but I see no microdata or RDF/A anywhere that I have looked there.

If no RDFa or microdata is found, often search engines will try to extract some data using some proprietary heuristics or microformats.

Steph.

Thank you. With the person search, I can see where the data comes from that google is returning in search results. The site searches are accompanied by a google ad for the webmaster structured data tool, hehe.

It is disconcerting that if I try to show someone the value of adding metadata to html, I can't simply do a search and show them how the details are coming from metadata. In nearly all searches that I have done to test this, I can find no corresponding metadata on the page.
