What is the difference between the Contact Person Primary
and Contact Organization Primary elements?
In developing the metadata standard, reviewers asked for a way to
distinguish cases in which the primary contact was a person, whose
organizational affiliation was incidental, versus those in which
the primary contact was an organization, whose personnel were
incidental. The Contact Person Primary element is for the first
case; the Contact Organization Primary is for the second. Both
are comprised of the same elements; the difference is which
elements are mandatory and which are optional.
