Overview of event messages and their status
The following event messages are supported by the NEMS for either publication and/or subscription by providers as indicated:
✅ Supported
❌ Not Supported
Requirements and population guidance within the event message specific pages should be followed in addition to the Generic Event Message Requirements within this specification.
Event maturity
The maturity of the event messages are indicated within the tables below. These event maturity labels are intended to indicate the expected stability of the event messages as follows:
| Event Maturity | Description |
|---|---|
| Alpha | Early proposal for an event message, high risk of change. |
| Beta | The event design has been agreed and is intended to become the release candidate but has not been proved through development and testing, therefore there is a risk that changes may be required. |
| Release Candidate | The event has been through a development and testing phase, followed by a successful DVP in live use. The event message should not change unless as a result of a live issue. |
| Released | Event is being widely used and is unlikely to change, unless a change is required as a result of a live issue. |
