And when you leave the domain of published text material many more events
are relevant on different levels:

- - (first) broadcasting of a TV piece (I remember a regional bibliography
  in austria which routinely covers these, because some formats include
  many interviews or portraits of persons of regional importance. Since
  not only the broadcasting firm but also the specific channel and program
  are relevant this could often be inherited from a bibliographic
  part/whole relationship as it might be done for articles in journals
  or newspapers)

- - exact submission or approval dates for technical reports (by whom or
  to whom?)

- - dates of reception (ingress?) for archival material, date of the post-stamp
  for letters

- - date of first public display for works of art (this may well be an
  exhibition as an identifyable entity, or just "19xx by Gallery yz")

I very much appreciate the shift from "Provider" to "Event" but I think
this has to be kept quite general since Bibframe cannot prescribe what
kinds of event a certain community deems important for specific materials
(some examples above are connected to questions of copyright status and
although outside of "bibliographic" questions may be of importance for
"library operations").

Any event seems to have dates or date ranges associated with it (from
years down to the granularity of minutes or seconds), many also explicit
places (as in cities or towns), and agents (corporate bodies typically).

Especially for manufacturing or publication events I do not understand
the concerns about re-use: The manufacture of 1000 copies of book X
and that of 2000 copies of book Y always are distinct events (even when
they happen in the same shop at the same time). We prefer to record only
year granularity and therefore yield identical descriptions for the events,
re-use however would imply they were the same event - that is not what
we want to express (I hope).

And (anonymous) subgraphs to my knowledge are the best and usually
only way to model a non-trivial data structure like needed for "events"
in RDF. Trying to flatten that out for some typical library situations
IMHO just conceals the general mechanics and - as this discussion has
shown so far - introduces a bunch of new problems.
