Sub-Use Cases



Co-ordinate Access Activities receives an order request from Consumer and provides a DIP to Deliver Response

  • Consumer
  • Co-ordinate Access Activities
  • Deliver Response
  • Data Management>Perform Queries
  • Data Management>Generate Report



Consumer submits order request (no reference use case number, as this is an externally initiated action)

Successful outcome

Deliver Response receives DIP

  1. Co-ordinate Access Activities receives an order request from Consumer (OAIS s, p 4-15)
  2. Co-ordinate Access Activities evaluates resources available to respond to request (OAIS s, p 4-15)
  3. Co-ordinate Access Activities evaluates Consumer's authorization to access requested information (OAIS s, p 4-15)
  4. Co-ordinate Access Activities provides notification of acceptance/rejection of Consumer's order request to Deliver Response (OAIS s, p 4-15)
  5. Co-ordinate Access Activities sends DIP request to Generate DIP(OAIS s, p 4-15; OAIS Figure F-1: Composite of Functional Entities)
  6. Co-ordinate Access Activities receives DIP from Generate DIP (OAIS s, p 4-15; OAIS Figure F-1: Composite of Functional Entities)
  7. Co-ordinate Access Activities sends DIP to Deliver Response (OAIS Figure 4-7: Functions of Access; OAIS Figure F-1: Composite of Functional Entities)

OAIS s, p 4-15 The Coordinate Access Activities function provides a single user interface to the information holdings of the archive. This interface will normally be via computer network or dial-up link to an on-line service, but might also be implemented in the form of a walk-in facility, printed catalog ordering service, or fax-back type service. Three categories of Consumer requests are distinguished: …and orders, which may access either or both Data Management and Archival Storage to prepare a formal Dissemination Information Package (DIP) for on- or off-line delivery. An order may be an Adhoc Order… This function will determine if resources are available to perform a request, assure that the user is authorized to access and receive the requested items, and notify the Consumer that a request has been accepted or rejected (possibly with an estimate of request cost and an option to cancel the request). It will then transfer the request to Data Management or to the Generate DIP function for execution. This function also provides assistance to OAIS Consumers including providing status of orders and other Consumer support activities in response to an assistance request.

  • An "order" is the OAIS term for a request to prepare and deliver a DIP to the Consumer. Orders may be initiated by the Consumer, or Administration on behalf of the Consumer. This use case addresses only those orders directly initiated by the Consumer. For orders initiated by Administration, refer to UC-6.5 Co-ordinate Administration Dissemination Request
  • Orders referred to in this sub-use case (and in UC-6.1 as well) are Adhoc Orders as described on OAIS page 2-10 (section 2.3.3). Event Based Orders are addressed by use case UC-6.5
