HAI Use Case: View/set user-roles and their mapping to URLs

From OPeNDAP Documentation

Point Of Contact: Nathan Potter

1 Description

View/set user-roles and their mapping to URLs

2 Goal

To provide Admin control of the relationships between user-roles and the URL's offered by the Hyrax server.

3 Summary

The Admin logs into the HAI and navigates to the page (or portion thereof) that contains the user-roles interface. There the Admin can:

  • create roles
  • delete roles
  • edit the URL pattern(s) that are mapped to this role.
  • add a user to a role
  • remove a user from a role.

4 Actors

  • Admin
  • HAI
  • Users

5 Preconditions

  • A Hyrax service running with users and authentication enabled.
  • The Administrator has authentication privileges for the HAI.


6 Triggers

The Admin needs to change the user-roles for an instance of Hyrax. This could arise from the need to add a new user, remove a user, change a user's access, etc.


7 Basic Flow

  1. The Admin logs into the HAI
  2. The Administrator uses the HAI to navigate one or more pages to the user-roles interface.
  3. Hyrax returns a page (or portion thereof) with the user-roles interface.
    In the user-roles interface the Admin can:
    • Create roles
    • Delete roles
    • edit the URL pattern(s) that are mapped to this role.
    • Add a user to a role
    • Remove a user from a role.

8 Alternate Flow

Here we give any alternate flows that might occur. May include flows that involve error conditions. Or flows that fall outside of the basic flow.

9 Post Conditions

Here we give any conditions that will be true of the state of the system after the use case has been completed.

10 Activity Diagram

Here a diagram is given to show the flow of events that surrounds the use case.

11 Notes

There is always some piece of information that is required that has no other place to go. This is the place for that information.
