Scope note: This class comprises activities that result in the allocation of an identifier to an instance of any subclass of E1 CRM Entity. An F40 Identifier Assignment may include the creation of the identifier from multiple constituents. Explicit reference to the used constituents can be made using the property P142 used constituent (was used in). The syntax of the identifier and the kinds of constituents to be used in constructing it may be declared in a rule. The construction of controlled access points for the names of persons, families and corporate bodies following specific cataloguing rules is a typical library application of identifier assignment. F40 Identifier Assignment also includes the assignment of controlled access points for works or expressions. Examples: - Assigning the controlled access point ‘William, Prince, Duke of Cambridge, 1982-’ as a controlled access point for a personal name, using the Anglo-American Cataloguing Rules, 2nd edition. - Assigning the controlled access point ‘Library and Archives Canada’ as an authorised controlled access point for a corporate body name, using the Anglo-American Cataloguing Rules, 2nd edition. - Assigning the controlled access point ‘Bibliothèque et Archives Canada’ as an authorised controlled access point for a corporate body name, using the Règles de catalogage anglo-américaines, 2e édition. - Assigning the controlled access point ‘Goethe, Johann Wolfgang von, 1749-1832. Faust. 1. Theil.’ as an authorised controlled access point for a work. - Assigning the controlled access point ‘Bible. English. American Standard’ as an authorised controlled access point for an expression.
