Assign unique identifiers to a description

Requirement number	MTD-1.1.1
Requirement name	Assign unique identifiers to a description.
Requirement specification	The application must be able to: Assign one or more unique identifiers (codes) to descriptions. Include in the identifier components that represent the institution that is responsible for the description and its country of origin.
Source quotation	ISAD(G) 3.1.1 OSARIS
Associated functional requirements	FNC-2.5.1 Identify units of description
Associated quality requirements	The application should be able to: Keep database IDs (automatically generated by the application and hidden from user) separate from reference codes (assigned by the archivist and meaningful to users). Support auto-entry of next available reference code upon record creation. Automatically concantenate a repository's institution and country identifiers with the description reference code to ensure unique identifiers in a multi-repository system (user should not have to manually enter institution and country codes).
Associated technical requirements
ICA-AtoM fields	information_object::id information_object::identifier
ICA-AtoM implementation	ICA-AtoM automatically assigns each record a unqiue database ID (id); this value is invisible to users. Users enter their own Reference code (identifier). ICA-AtoM allows any type of value in this field (numbers, text, alpha-numeric code) to accommodate any institutional system for assigning identifiers.
Known issues	ICA-AtoM (v0.6) cannot currently auto-generate next sequential reference code / number.
