The National Interface represents the interface between the WorkflowManager and the NationalConnector.

The NationalConnector is not an epSOS Common Component, but a collection of adapters to the national protocols and data formats. The NationalConnector makes use of a common exposed API  as required by the WorkflowManager. Also, it exposes a common API to the WorkflowManager itself (called National Interface). Interfaces of the NationalConnector exposed to the national infrastructure are country-specific. The NationalConnector is responsible to access the national infrastructure and fulfil the national requirements.
