[Final] 

== Definition ==
The Use Case "Doing Business in Another Member State" of the [[Doing Business Abroad Pilot]] (DBA UC2) uses the [[Subscription and Notification Pattern]].

This use case focusses at assessing the consequence for active eServices in case of a business event, e.g. company goes bankrupt, company stops it’s activities, company merges, etc. The data consumer may subscribe to notifications on selected business events. In case such an event occurs, the data provider notifies the data consumer. The data consumer needs to assess the relevance of the notification. It can then for example request the updated data from the data provider or decide it doesn’t need any additional data. Furthermore, the data consumer may intervene in an active eService (e.g. stop periodical grants or impose a tax obligation). The data consumer may also use the notifications as input to a general fraud prevention and protection procedure.
== Major design decisions ==
BRIS will not be used for subscription & notification. The notifications send resorting under BRIS regulation are out of scope of DE4A. The DE4A pattern has its own subscriptions and notifications that do no relate to BRIS regulation. Note that in some cases this could lead to the situation that a Data Evaluator receives both a BRIS and a DE4A notification for one business event.

Note the BRIS proposed change in the technical working group: Subscription will be replaced by a push notification through registering international branches in the registry of the mother company. Thereby reversing the responsibilities.

== Legal Consideration ==
[Starting from exciting national and union law: Looking at this specific use case of DBA, we should     have an analysis of applicable law to uncover what is and what is not  possible today, given the specific combination of MS that are participating in the exchange. Cooperation between the pilot DBA and legal experts in the DE4A program. If we are able to get to a preliminary analysis in the next two to three weeks we might include it in the DBA chapter of D2.5. Otherwise it could become a working paper in context of the solution architecture for the new DBA pattern.]
