Go try the URI and see what the author says. If he didn't, use it whatever
way you want. If the author is not careful of making such statement, it is
his careless. If the author says one way, and you insist the other way,
then it is your ignorance or arrogance.


Suppose the URI is
http://www.knox.edu/Images/_News/news_media/img/2005/obama-barack-1ss.jpg

According to your proposal, what can I use it for in RDF?

First, the presumption is that we will have an assertion of the sort like the follows?

http://www.knox.edu/Images/_News/news_media/img/2005/obama-barack-1ss.jpg ex:license ex:l1.

Where did it come from? Any more explicit assertion can come from the same source. It is up to you to trusted it.

Second, use content negotiation?
