Dear Thanasis, All,

This is a good summary, but I would like to point out, that there is a 
fundamental distinction between ontology and uncertainty. Uncertainty is 
a question of knowing (epistemology), and not being (ontology) and 
pertains to all facts being. Therefore a solution must be generic and 
independent from the ontology. Another approach to have properties of 
uncertainty from CRM Entity and Primitive Value, and create combinations 
of these with the ontological ones. It is equivalent to a .2 property, 
but computationally efficient, and standard RDF. It only blows up the 
RDFS, but that can be generated automatically.

E13 introduces an additional agency, and is computationally heavy, as 
all reification-equivalent constructs.

All the best,
