I do not consider using "linked data" to be "scraping" by any meaning of 
that term. Machine-actionable data is returned in formats like RDF/XML 
or ttl or JSON. And I'm curious that linked data is somehow not 
considered to be usable as "data" and that microformat data is not 
considered to be searchable -- in fact, its raison d'etre is search 
optimization.

But is it available to everyone, and is the data retrieved also usable 
as ODC-BY by any member of the Web public?
