Re: Yahoo RDFa enahced results example

Hi Eugenio:

ago

), am I >wrong?

Yahoo announced the support for RDFa in the SearchMonkey index last autumn.

That meant, they started crawling RDFa on the basis of a set of selected 
vocabularies (foaf, sioc, goodrelations, ...)
and make the resulting meta-data available for Yahoo-internal and other 
applications via
the extra SearchMonkey index.

Since then, application developers have been able to access that index 
for their own software or build own search engines with the Yahoo BOSS 
framework.

For example, we wrote a small demo app that mimics Yahoo search and 
shows the RDFa meta-data for any page as in the Yahoo index, if any such 
data is available:

http://goodrelations-search.appspot.com/

(Note that the N3 output has quite some quirks as compared to what 
PyRDFa extracts; there is a bug at Yahoo's side, but they are working on 
that).

In a nutshell: Until recently, SearchMonkey meta-data was visible only

- inside BOSS-applications or
- if you were signed in to Yahoo AND activated an extension from the 
Yahoo SearchMonkey gallery or
- if you were signed in to Yahoo AND wrote your own extension based on 
SearchMonkey meta-data.

Now, very recently Yahoo announced that SearchMonkey meta-data for a 
couple of typical page contents, namely GoodRelations-based price 
information,
would be used to improve the rendering of the general Yahoo search 
results pages - i.e., for anybody, without the need to use any extra 
software or signing in.

That is a major innovation because it creates an incentive for any 
business in the world to use GoodRelations and other vocabularies for 
augmenting their pages.

I hope that clarifies the issue.
