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 assign one or more unique identifiers (codes) to descriptions. In a multi-repository system (network), the identifier should include include components that uniquely identify the institution that is responsible for the description and its country of origin. |
| Context (parent requirements) | |
| Source quotation | |
| Associated functional requirements | |
| Associated quality requirements |
Separate database IDs (automatically generated by the application and hidden from user) and reference codes (assigned by the archivist and meaningful to users). Support auto-entry of next available reference code upon record creation. Automatically concantenate repository's institution and country identifiers with the description reference code to generate a unique identifier in a multi-repository system (user should not have to manually key 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. |
