Hi all,

How do we address this issue?
The current definition is:

A primary source^ ◊ 
<http://www.w3.org/TR/prov-dm/#concept-primary-source> for a topic 
refers to something produced by some agent with direct experience and 
knowledge about the topic, at the time of the topic's study, without 
benefit from hindsight.

I wonder whether the wording 'refers to' is suitable here. We don't mean 
'is', but 'a derivation from'. Would this address the concern?

> The definition of a "primary source" implies that it is an entity when in fact the term qualifies the role that a given entity plays during the creation of a new entity, not the derivation itself. This might seem to be a minor point, but it is clearly different from both revision and quotation, both of which could be used when deriving a new entity from an entity used as a primary source.
> It is also important to note that a given entity might be a primary source for one entity but not another ("primary source" is context-dependent).
