The stars are to encourage people *toward* Linked Open Data -- both Linked Data and fully Open Data.

Because PDF is not RDF, and Linked Data is based on RDF. You could call it Linked Stuff or hyperdata or something else like that *if* it contains links. But "Linked Data" has a well-established meaning in the community -- in spite of Kingsley's claims to the contrary -- and that meaning includes being based on RDF:

them. The format is a pain, that's why they only get 1 star.
I was not saying that PDFs cannot have links in them. I was pointing out that the stars on the Linked Open Data coffee cup do *not* indicate that there is such a thing as "one-star Linked Data" or "four-star Linked Data". Think about it. Suppose you have a PDF document **that has no links** and you put it on the web under an open license. Would it make any sense to call it "Linked Data" just because it is on the web with an open license (thus fulfilling the requirements of the first star)? Of course not. But it would qualify for one star on the path *toward* Linked Open Data.
