Request presentation use
In order to use the request presentation UI, a valid OpenIoT account is required. When the user first launches the request presentation UI they will be automatically redirected to a log-in screen. After a successful log-in, the user will be redirected to the main application UI.

To open a specific application dashboard click the open application menu and select one of the available applications. A dashboard containing all sink nodes that were defined in the selected applications will be generated and displayed. The dashboard data will be periodically updated every 1 minute.
This menu option allows the user to reload their applications from the openIoT repositories. The loaded applications will replace the currently loaded applications.

For using the Request Presentation application a service must have been created for it. When the OpenIoT graph is initialized, a service is created for the Request Presentation with the following address, key and secret as defined in the openiot.properties:
- security.initialize.reqPres.prefix=http://localhost:8080/ui.requestPresentation
- security.initialize.reqPres.secret=requestPresentationUI-secret
- security.initialize.reqPres.key=requestPresentationUI
Currently, for using the application, no permissions are needed for the user on the request definition service. However, the user must have the permission "*" on the Scheduler and SD&UM services.
The security configuration for the Request Presentation application is located in security-config.ini in the JBoss configuration directory. The configuration content is delimited by @BEGIN-requestPresentation and @END-requestPresentation.
