Project Management

Use-Cases

Actor Use-case Description
CAP profile implementer Implement CAP profile CAP Profile defines a class of CAP alerts which may provide a structure to the CAP alert and speed up the creation of CAP Alerts and templates, for example a Profile may specify a region, a set of languages and generic templates in each language. This can be used during CAP alert creation for centering the map for example and for fast creation of alert messages
CAP template implementer Implements CAP templates CAP templates are Abstract CAP alerts with blanks that need to can be filled really fast in case of an imminent disaster to produce a CAP alert, for example a Tsunami CAP template might be of help in a coastal area, hence an implementer will create the same
CAP message editor Send a CAP alert a message editor can pick a CAP template and fill the blanks in it to send out a CAP alert (user story in description)
CAP alert subscriber Subscribes to CAP Alerts when a CAP alert is created and the subscriber is in the audience, a notification will be issued via modes prescribed by the subscriber

Design

  • The Models: The table definitions go are in modules/s3db/cap.py. Place some functions which will help in the creation, sending and receiving of CAP XML files in s3msg module where it might best fit.
  • The GUI
    • index: A map and a table of alerts sortable by the various fields of an alert. Clicking on a row on the table centers the map to the <Area> associated with the alert.
    • profiles:
      • index: View a listing of templates (We should ship some country-specific profiles by default in Eden since this is recommended)
      • edit & create: Editing / creating a profile. This should allow for specification of constraints for each field of the cap message.
    • templates:
      • index: View a listing of all templates grouped by their pertinent profiles.
      • edit & create: Allow users to create templates: This will allow for creating multiple <info> elements with placeholders for canned inputs such as [AREA] [SEVERITY] etc.which will then be substituted to produce text consumable via various media like SMS and IVR
    • create alert: A map with ability for easy input of polygons and circles, A drop-down for picking profiles and templates to use. A way to specify recipients for restricted alerts.
    • Reference and mockups: http://eden.sahanafoundation.org/ticket/1026

Implementation

Notes

Common Alerting Protocol:

Originating CAP alerts is one need, receiving them and using them to actuate alerting systems, be they SMS drivers or sirens or whatever is another. Another is a message broker that can interoperate with the commercial boxes. Authentication systems are also a factor, especially where cross-jurisdictional reciprocity is required

Ideally the CAP XML should be signed end-to-end, especially in a federated system where there's more than one authority running servers/aggregators. Our current implementations sign the alerts at the originating server, so they're at least traceable to the source server but not necessarily the individual operator. Current servers check integrity when they get a message from another server, but there isn't a regional PKI.

  • The wireframe built using Python and Eden frameworks.​ The code is here. Anyone can use this as the basis to continue the CAP Broker developments.
  • This ticket contains some of the screen shots and initial GUI layouts with some descriptions.
