Hello all,
This issue is not quite new, we discussed E74 in the context of working on
LRMoo at the Cologne meeting. This proposal results from the resolution we
favoured at the time.
ISSUE: Definition of E74 Group, add text to scope note of E21 Person
In the entity hierarchy E74 Group is a subclass of E39 Actor, and a superclass
of E40 Legal Body, as well as of F11 Corporate Body and F39 Family from FRBRoo
(LRMoo). E39 Actor is equal to LRM-E6 Agent, which is the superclass for LRM-E8
Collective Agent (which is the superclass of F11 Corporate Body and F39
Family). Structurally then, E74 Group should be equal to LRM-E8 Collective
Agent. However, the scope note of E74 Group is broader than LRM-E8 and includes
certain groups that are not actually agents (LRM-E6) and which would not
actually be instances of E39 Actor.
Propose to modify the scope note of E74 Group so that it clearly corresponds to
LRM-E8 Collective Agent. To do this any groups of people not having agency,
such as national, religious, cultural, ethnic groups, must be excluded from the
scope of E74. In this way there is no problem with E74 as a subclass of E39
Actor or superclass of E40, F11 and F39. Nothing needs to change formally,
however certain instances attributed to this class may be incorrect. New and
changed text in yellow.
E74 Group
Subclass of: E39 Actor
Superclass of: E40 Legal Body
Scope note: This class comprises any named gatherings or organizations of two
or more people that act collectively to produce some intentional result for
which they can be collectively considered responsible.
In the wider sense this class also comprises holders of
official positions viewed collectively, which used to be regarded in certain
contexts as one actor, independent of the current holder of the office, such as
the president of a country. In such cases, it may happen that the E74 Group
never had more than one member.
A joint pseudonym (i.e., a name that seems indicative
of an individual but that is actually used as a persona by two or more people)
is a particular case of E74 Group.
A gathering of people becomes an E74 Group when it exhibits sufficient
organizational characteristics to be collectively held responsible for actions
performed together. These might be communication, creating some common
artefact, a common purpose such as study, worship, business, sports, etc.
Occasional groups and groups that are constituted as meetings, conferences,
congresses, expeditions, festivals, fairs, etc, are examples of E74 Group as
long as they are identified by a specific name, rather than a generic
description of the gathering, and can act as a unit (such as by publishing
their proceedings, or approving a report). These collective actions may be
performed by representatives selected by the whole, rather than by all
individual members acting together.
Married couples and other concepts of family are regarded as particular
examples of E74 Group.
Examples:
* Exxon-Mobil (E40)
* King Solomon and his wives
* The President of the Swiss Confederation
* Nicolas Bourbaki
* Betty Crocker
* Ellery Queen
Properties:
P107 has current or former member (is current or former member of): E39 Actor
(P107.1 kind of member: E55 Type)
ISSUE: Decision to not duplicate CRM classes in LRMoo results in deprecating
F10 Person as it is equivalent to E21 Person.
Consequence: Present F10 scope note includes additional text not present in the
E21 scope note.
Propose to add the text in yellow highlight to E21. It seems generally
applicable with little modification. Text in green highlight in F10 scope note
is valid, but may be better elsewhere, as in the LRMoo overview.
E21 Person
Subclass of: E20 Biological Object
E39 Actor
Scope note: This class comprises real persons who live or are assumed to have
lived.
Legendary figures that may have existed, such as Ulysses and King Arthur, fall
into this class if the documentation refers to them as historical figures. In
cases where doubt exists as to whether several persons are in fact identical,
multiple instances can be created and linked to indicate their relationship.
The CRM does not propose a specific form to support reasoning about possible
identity.
In a bibliographic context, a name presented following
the conventions usually employed for personal names will be assumed to
correspond to an actual real person (E21 Person), unless evidence is available
to indicate that this is not the case. The fact that a persona may erroneously
be classified as an instance of E21 Person does not imply that the concept
comprises personae.
Examples:
* Tut-Ankh-Amun
* Nelson Mandela
F10 Person
Equal to: E21 Person
Scope note: This class comprises real persons who live or are assumed to have
lived. Bibliographic identities or personae assumed by an individual or a group
should be modelled as F12 Nomen and connected to the relevant person or group
with an instance of F35 Nomen Use Statement, even if nothing more can be said
about this person or group. In a bibliographic context, a name presented
following the conventions usually employed for personal names will be assumed
to correspond to an actual real person (F10 Person), unless evidence is
available to indicate that this is not the case. The fact that a persona may
erroneously be classified as an instance of F10 Person does not imply that the
concept comprises personae.
