>I think your concerns can be expressed thus:
>1. The Concepts document is not clear that RDF does not define a mechanism 
>for distinguishing asserted and non-asserted forms.

changing the subject line


>2. The informal example in section 4.1 can be read as suggesting RDF 
>defined means to express propositional attitudes.  We should be clear that 
>propositional attitudes are not supported.
>You also raise an issue of provenance, but I don't think that impacts the 
>Concepts document.
>(You also note RDF's lack of a mechanism to refer to a graph;  by my 
>recollection, this idea, or something very like it, was discussed but 
>considered out of scope for the current WG effort, and has been noted as 
>an issue for possible future consideration.  I don't think there's 
>anything else we should say in our documents.)
>If this adequately captures your concerns, I'll ask Brian to raise an 
>issue for this, so the WG can consider your comments and get back to you.
>>The second issue is the question of unasserted forms/statements.
>>I am unable to find an RDF example of how to represent

>>I find an example showing exactly what is meant by an
>>unasserted RDF statement. (If there are examples, they are not

>>These are what I referred to as unanwered issues.  I'm hoping that
>>someone will tell me what the "official" position is.
>>My last e-mail summarized my position
>>as to these two issues, so I won't go any deeper here.
