+8.  Event IDs in cFE (and across the other cFS components/apps) should be capitalized and use

+    <APPLICATION\_NAME>\_<EVENT>\_<EVENT\_TYPE>\_<EID>

+    | CFE_EVS_NOOP_INF_EID | CFE Event Service | NOOP Command | Informational | Event ID |
+    | HS_CR_PIPE_ERR_EID | Health & Safety | Create Pipe Error | Error | Event ID |
+
+    Common events should be named consistently across applications for ease of recognition.

+    Common command/event descriptions include:
