+# Action
+
+An *action* is a metadata entity that describes an activity required by the governance defined for the open metadata ecosystem.  There are two types of action:
+
+* A [To Do](/concepts/to-do) is an action that must be performed by a third party, typically a person.
+* An [Engine Action](/concepts/engine-action) is an automated action that is performed by a [governance engine](/concepts/governance-engine).

+# Context Event
+
+A *Context Event* describes an event in time.  It may be a moment in time or a time period.  It is used to explain anomalies or changes in data or activities.  It is also used to provide scope and timelines to projects and other activities.

+# Event Action Engines
+
+An *event action engine* describes a set of related [event action services](/guides/developer/event-action-services/overview). Each event action service implements a specific type of event management.  This event management is built around [context events](/concepts/context-event) and actions.
+
+An event action engine is hosted in the [Event Action Open Metadata Engine Service (OMES)](/services/omes/event-action/overview) running on one or more [Engine Host OMAG Servers](/concepts/engine-host).
+
+![Event Action Engine](/connectors/event-action/event-action-service.svg)
+
+When an event action engine is called, it is passed a governance request type and request parameters. This is mapped to a call to an [event action service](/concepts/event-action-service) through the [event action engine definition](/concepts/governance-engine-definition).

+
+    The Open Metadata Types used to define the event action engines are located in [model 0461 Governance Engines](/types/4/0461-Governance-Engines).

 The unique name of the governance engine defined in the governance engine definition is added to the [OMES configuration](/guides/admin/servers/configuring-an-engine-host/#configure-engine-service).  When the [engine host](/concepts/engine-host) starts up the OMES, it reads the *governance engine definition* from its partner [metadata access server](/concepts/metadata-access-server) to complete its initialization.  The engine host monitors changes in the governance engine definition so the services within the governance engine can be dynamically maintained.
 
-Calls to the governance engine are made by creating [engine actions](/concepts/engine-action in the open metadata ecosystem.  The engine host is monitoring for new governance actions for the governance engine.  When one occurs, it claims the governance action and passes on the request to the governance engine to run.  The claim process is used since there may be multiple engine hosts running that governance engine and only one of them should process the request.

-> A governance action can be created anywhere in the open metadata ecosystem.  The result is an event that is passed via its connected metadata access server to the engine host.  If the request is for a governance engine that it is hosting, the engine host claims the governance action and passes the request to the governance engine.
