Cross-border Subscriptions
Revision as of 11:57, 1 July 2021 by Ictu mavi.cristache (talk | contribs)
The Cross-border Subscriptions application collaboration consists of various co-operating application components implementing multiple application services used by both Notification Process Realization (DP) and Subscription Process Realization (DP). It implements:
- the full life cycle of subscriptions (CRUD) in a MS and offers functionality to validate and confirm subscriptions as well as error handling;
- event handling, i.e. filtering local (national) events for relevant cross-border events and creating the notifications messages and preparing the list of subscribers for particular cross-border events that need to be dispatched;
- notifications of events, it provides a UI (front-end) in order to inspect log files and manually dispatch events if needed. A back-end serves this front-end and connects with the event handling.
It uses interfaces to communicate with the Base Registry of companies in the MS.
