Group

Version: 1.0

The Group reference data model provides a list of standard descriptors (fields) that are typically present in the description of a Group or institution in cultural heritage data systems. The intention of this reference model is to provide a consolidated, high-level formal structure comprising the most commonly reused descriptors for a Group.

Group Names and Classifications

The attribution of names and types to things, including Groups, is a basic human activity. The disambiguation of Groups is aided by the understanding of the various names and identifiers that have been given to a Group at different moments in time. Moreover, classifications such as Group type and legal status can help in identifying and studying Groups over time.

Group Parthood

Groups often exist in complex internal structuration with relations of subsumption towards sub-parts of the Group. This information category gathers together the basic descriptors typically deployed to this end.

Filed ID Name Description Data Type CRM Path
LAF.18 Members This field is used to link the documented Group to an instance of person or Group which is a member of it. Reference Model [Person] ->p107->E21[18_1]

Group Existence

Of essential importance in identifying and tracking Groups is to know when they came into existence as such. For this reason, we have clustered descriptors relevant to such information into a common ‘existence’ category tracking the formation of a Group. These are described in the table below.

Filed ID Name Description Data Type CRM Path
LAF.142 Organization Formed By This field is used to link the documented group formation activity to an actor responsible for carrying it out. Reference Model [Person/Group] ->P95i->E66[139_1]->P14->E39[142_1]
LAF.139 Formation Place This field is used to link the documented group formation activity to a location at which it was carried out. Reference Model [Place] ->P95i->E66[139_1]->P7->E53[139_2]
