Dear George,
Actually I agree, I propose to detach the discussion of what an auction
lot is completely from curated holdings and aggregates. I propose this
change of scope note independent from auction lots.
In auction houses, there exist kinds of auctions which require the
objects to be physically transferred to the house. With the notion of
e-auction, the whole concept blurs completely. I or someone else could
try to contact an expert for the auction concepts.
There is a Europeana white paper about collections I participated in the
writing. It makes exactly the distinction you talk about. We
distinguished physical holdings from referential collections - we may
also call them "epistemic collections", or referential sets.
Their identity is declarative, and used to summarily refer to anything,
without any claim about their commonalities, and without material control.
Best,
Martin

Hi Martin,
I think it's clear an auction lot is not a curated holding. The change
of scope note can be fine but it doesn't really get to the heart of
the question. An auction lot is not an aggregate of physical things
but is a declarative set of objects. They need never have been
aggregated together and therefore it would be wrong to model them as
either E19 or E78. Moreover, the things sold in auction lot can be not
only a physical thing, but a concept, an experience, whatever.
To me it raises the question of what is actually exchanged in an
acquisition which, and I know this would be a breaking change, does
not seem to me to be the physical object at all but a right over
something.
While improving the scope note is always nice, I think that the heart
of the discussion here might be elsewhere in terms of what is
exchanged in an acquisition event and how to describe declarative sets
of things that are neither aggregates in the sense of E78 nor
aggregates in the sense of E19.
Look forward to the live discussion.
Best,
George

Dear All,
Here my proposal to make clear that an auction lot or exhibition
set is not a curated holding:
*OLD*
E78 Curated Holding
Subclass of:
E24 <#m_-8136630108576602709__heading=h.2dlolyb> Physical
Human-Made Thing
Scope note:
This class comprises aggregations of instances of E18 Physical
Thing that are assembled and maintained (“curated” and
“preserved,” in museological terminology) by one or more instances
of E39 Actor over time for a specific purpose and audience, and
according to a particular collection development plan. Typical
instances of curated holdings are museum collections, archives,
library holdings and digital libraries. A digital library is
regarded as an instance of E18 Physical Thing because it requires
keeping physical carriers of the electronic content.
Items may be added or removed from an E78 Curated Holding in
pursuit of this plan. This class should not be confused with the
E39 Actor maintaining the E78 Curated Holding often referred to
with the name of the E78 Curated Holding (e.g. “The Wallace
Collection decided…”).
Collective objects in the general sense, like a tomb full of
gifts, a folder with stamps or a set of chessmen, should be
documented as instances of E19 Physical Object, and not as
instances of E78 Curated Holding. This is because they form wholes
either because they are physically bound together or because they
are kept together for their functionality.
Examples:
the John Clayton Herbarium
the Wallace Collection (Ingamells, 1990)
Mikael Heggelund Foslie’s coralline red algae Herbarium at Museum
of Natural History and Archaeology, Trondheim, Norway
The Digital Collections of the Munich DigitiZation Center (MDZ)
accessible via https://www.digitale-sammlungen.de/
<https://www.digitale-sammlungen.de/>at least in January 2018.
In First Order Logic:
E78(x) ⇒E24(x)
Properties:
P109 <#m_-8136630108576602709__heading=h.ibhxtv> has current or
former curator (is current or former curator of): E39
<#m_-8136630108576602709__heading=h.pkwqa1> Actor
*NEW*
Scope note:
This class comprises aggregations of instances of E18 Physical
Thing that are assembled and maintained (“curated” and
“preserved,” in museological terminology) by one or more instances
of E39 Actor over time for a specific purpose and audience, and
according to a particular collection development plan. *The
diachronic identity of an instance of curated holdings is given by
the continuity of the evolution of its contents according to the
same development plan and its adequate modifications, and not by
any essential part. Essential changes of the development plan and
a corresponding reorganization of the curated holdings may however
be regarded as transformation into a new instance of curated
holdings. *
Typical instances of curated holdings are museum collections,
archives, library holdings and digital libraries. A digital
library is regarded as an instance of E18 Physical Thing because
it requires keeping physical carriers of the electronic content.
Items may be added or removed from an E78 Curated Holding in
pursuit of this plan. This class should not be confused with the
E39 Actor maintaining the E78 Curated Holding often referred to
with the name of the E78 Curated Holding (e.g. “The Wallace
Collection decided…”).
Collective objects in the general sense, like a tomb full of
gifts, a folder with stamps or a set of chessmen, should be
documented as instances of E19 Physical Object, *and not as
instances of E78 Curated Holding, because, in contrast to the
above, their identity is given by the constellation of their
parts, physically bound together or kept together for their
functionality, regardless whether parts are lost, destroyed, or
replaced by substitutes and regardless the duration of the process
that brought them together into their identifying constellation.*
