Exactly. Read the criteria above for the stars, and think about it. Suppose a JPEG image is placed on the web with an open license. Would it make any sense to call it "Linked Open Data", just because it meets the criteria for one star? Certainly not, as that would render the term completely meaningless. And as a second example, notice that linking only comes into play with *five* stars: data meeting the first four stars is not even linked! It would not any make sense at all to call something "4-star Linked Open Data" if it is not even linked! The only sensible interpretation of the stars is that they indicate milestones of progress *toward* "Linked Open Data" -- *not* that there are five levels of Linked Open Data. David
