Re: Primary Source again (Re: PROV-ISSUE-518: Data Model Section 5.2.4 ) [prov-dm]

All,
Here is a proposed answer to this issue. When Tim confirms he is OK, I 
will implement it.
Comments, feedback?
regards,
Luc


      ISSUE-518 (PrimarySource)

    * Tracker: http://www.w3.org/2011/prov/track/issues/518
    * Group Response
          o Following the author's suggestion the Working group proposes
            to revise the definition of Primary Source as follows:
                + A primary source is a derivation from an entity that
                  was produced by some agent with direct experience and
                  knowledge about the entity's conceptual topic, at the
                  time of the topic's study, without benefit of hindsight.
          o We also propose to add the following comment, inspired by
            this issue:
                + It is also important to note that a given entity might
                  be a primary source for one entity but not another. It
                  the reason why Primary Source is defined as a relation
                  as opposed to a subtype of Entity.

>> 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.
