Jeremy Carroll asks for use cases for unasserted RDF. There are many contexts in which one wants to refer to a statement without asserting it. Jonathan Borden described IF THEN statements. Others include: I heard FOO. (I'm not sure whether I believe it...) Tim believes FOO. (But I don't necessarily...) Libby says FOO. (I don't know if it's true.) FOO is false. where, in each case, FOO is a piece of RDF. For example, in an information repository project I've been involved with [1], we record every statement that's been made, automatically inferred, or input into the repository. We do NOT, in general, want to believe all of these statements. (For example, we collect information from email, web browsing, etc. We also automatically infer type information, authorship, etc., sometimes erroneously. Finally, users can hand annotate information and may do so in error.) It would be lovely to represent all of these statements in RDF, but we do NOT want to assert them all!
