Hello all,

I've seen a couple members of this list twitter about this  
announcement, but I thought it would be good to mention it here a  
little more formally. As of yesterday,[1] Yahoo! has started providing  
all of the semantic data we've harvested directly through our BOSS  
Search API.[2] Previously, this data was only available in the  
SearchMonkey developer tool,[3] and was difficult to see in bulk.

A little easter egg: if you want to see how many URLs we have with  
RDFa, you don't need to call the BOSS API. Instead just use the  
following search:


We think that's actually an undercount; Ben Adida and others have  
provided some helpful suggestions for refining how our extractor  
works, and I expect we will be harvesting RDFa even more voraciously  
in the coming months. :)

If you want to compare our RDFa coverage to our microformat coverage,  
use searches like:


where <microformat> is hcard, hresume, etc.

Best regards,

Evan Goer
