Well, ok, I'll set aside my questions of how this data will get into Hadoop for now. A more fundamental question is who is going to set this up? †Vendors? The libraries?
I disagree. Knowing the name of something, its type(s), and a few other seemingly mundane clues can be enough to identify a thing in a broader context. RDF/Linked Data is not merely a variant record format. Patterns exist in information that extend well beyond records, even if they are only probabilistic. Donít underestimate Hadoop.
