RDF does have a standard way to declare the origin of a statement (presume
an opinion is derived from a statement). This is the distinction between a
statement and stating and is the point of statement "reification". The point
is that since everything is a resource, one can make statements about
statements which is how I assume one might make a statement regarding the
origin of a statement.
suppose:
<RDF>
<Statement ID="S1">
<subject resource="#peppers"/>
<predicate resource="#are" />
<object resource="#hot" />
</Statement>
<Statement ID="S2">
<subject resource="#jon">
<predicate resource="#believes"/>
<object resource="#S1">
</Statement>
<Statement ID="S3>
<subject resource="#fred" />
<predicate resource="#asserts"/>
<object resource="#xpointer(//Statement[2])">
</Statement>
</RDF>
Which yeilds the following English statements:
"Peppers are hot."
"Jon believes that peppers are hot."
"Fred asserts that Jon believes that peppers are hot."
