Use cases describe interactions with an application from the end-users' point of view in a variety of what if scenarios. Use cases:

  • Test the application's current functionality.
  • Identify issues that need to be addressed in future releases.
  • Support development of user-end documentation.


Use cases are clustered around the same broad categories as the functional requirements. Like the latter, use cases are organized hierarchy with high-level scenarios broken down into more specific tests (sub- and sub-sub-cases). To facilitate cross-references and links, each case has been assigned an alpha-numeric code: the alpha prefix designates its type (UC = use case), the number establishes its position in the hierarchy. Six main use cases have been identified:

Use case actors

The following generic actors are invoked in the use cases:

  • Institution: a body having custody and control of archival materials.
  • Archivist: a staff member of an Institution.
  • Network: a group of Institutions sharing descriptions and other information relating to archival materials.
  • Administrator: a person responsible for the application of an Institution or Network.
  • Researcher: a person who accesses the archival materials held by Institutions.


Each use case includes some or all of the following information:


  • Use case number: UC-x.x.x, unique tracking number assigned to the use case.
  • Use case name: descriptive name assigned to requirement.
  • Context (parent requirements): links to higher-level cases, if applicable.
  • Sub-requirements: links to lower-level cases, if applicable.
  • Overview: brief description of the scenario.
  • Actors: the main actor(s) involved in the scenario.


  • Preconditions: other use cases whose completion is a precondition for the current case.
  • Trigger: the event that initiates the current case.
  • Successful outcome: the outcomes of a successful resolution of the scenario.
  • Main scenario: step-by-step breakdown describing the scenario as leading to a successful outcome.
  • Exceptions / variations: other possible variations, including unsuccessful outcomes ("Scenario B", "Scenario C" etc).


  • Functional requirements: links to associated functional requirements (FR-x).
  • Metadata requirements: links to associated metadata requirements (MR-x).
  • Technical requirements: links to associated technical requirements (TR-x).


  • Diagrams: work-flow or other diagrams illustrating the scenario.
  • User Manual: links to the User manual sections that provide step-by-step instructions for activities relating to the scenario.
