I would encourage everyone to have a look at the report from the recent
TDWG/GBIF Workshop on GUIDs:
One of the outcomes of this workshop was the need to clarify the distinction
between GUIDs assigned to data objecs, vs. GUIDs assigned to conceptual
entities. I was a member of a breakout group that discussed this
distinction, and we were tasked with creating a page or set of pages on the
Wiki to clarify this distinction -- particularly in the context of LSIDs
(the GUID technology which seemed to be strongly preferred by the workshop
participants). It's a subtle distinction with very significant implications
(it's also a topic muddled with unfortunate semantics). Our breakout group
concluded that GUIDs for conceptual entities serve an important role in
biodiversity informatics, if for nothing else than to serve as a "hub"
around which multiple data-object GUIDs may cross-reference each other.
So...James...in your example, there would probably be multiple data-object
GUIDs for the different digital "renderings"; and perhaps a separate
data-less GUID assigned to the the "concept" of the specific publication
instance, to which all of the alternative data-GUIDs may be "hubbed".
This group should also take note of point 5 under the "Work plan" section of
the Workshop Report, regarding the need for a sort of "Publication Bank".

But wouldn't we also want the "corrected" (="interpreted") date (or date
range) to be among the attributes -- even at level 1? If for no other
reason than estimating chronology?
