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.
