Class: identifier

comment "Scope note: This class comprises strings or codes assigned to instances of E1 CRM Entity in order to identify them uniquely and permanently within the context of one or more organisations. Such codes are often known as inventory numbers, registration codes, etc. and are typically composed of alphanumeric sequences. The class E42 Identifier is not normally used for machine-generated identifiers used for automated processing unless these are also used by human agents. [Adapted from the Scope Note of CIDOC CRM E42 Identifier ver. 5.0.1] F13 Identifier covers the notion of “controlled access points” in library practice – both preferred forms and cross references. A cross reference may not identify uniquely an entity, but can be shared by two entities; however, as it displays the same structural characteristics as preferred controlled access points, it is still regarded in the model as an instance of F13 Identifier. Examples: ISSN ‘0041-5278’ (F13) ISRC ‘FIFIN8900116’ (F13) Shelf mark ‘Res 8 P 10’ (E42) ‘Guillaume de Machaut (1300?-1377)’ (F13) [a controlled personal name heading that follows the French rules] ‘Guillaume, de Machaut, ca. 1300-1377’ (F13) [a controlled personal name heading that follows the AACR rules] ‘Rite of spring (Choreographic work: Bausch)’ (F13) " (en)
