-## Event schema
-
-Azure Policy events contain all the information you need to respond to changes in your data. You can
-identify an Azure Policy event when the `eventType` property starts with "Microsoft.PolicyInsights".
-Additional information about the usage of Event Grid event properties is documented in
-[Event Grid event schema](../../../event-grid/event-schema.md).
-
-| Property | Type | Description |
-| -------- | ---- | ----------- |
-| `id` | string | Unique identifier for the event. |
-| `topic` | string | Full resource path to the event source. This field isn't writeable. Event Grid provides this value. |
-| `subject` | string | The fully qualified ID of the resource that the compliance state change is for, including the resource name and resource type. Uses the format, `/subscriptions/<SubscriptionID>/resourceGroups/<ResourceGroup>/providers/<ProviderNamespace>/<ResourceType>/<ResourceName>` |
-| `data` | object | Azure Policy event data. |
-| `data.timestamp` | string | The time (in UTC) that the resource was scanned by Azure Policy. For ordering events, use this property instead of the top level `eventTime` or `time` properties. |
-| `data.policyAssignmentId` | string | The resource ID of the policy assignment. |
-| `data.policyDefinitionId` | string | The resource ID of the policy definition. |
-| `data.policyDefinitionReferenceId` | string | The reference ID for the policy definition inside the initiative definition, if the policy assignment is for an initiative. May be empty. |
-| `data.complianceState` | string | The compliance state of the resource with respect to the policy assignment. |
-| `data.subscriptionId` | string | The subscription ID of the resource. |
-| `data.complianceReasonCode` | string | The compliance reason code. May be empty. |
-| `eventType` | string | One of the registered event types for this event source. |
-| `eventTime` | string | The time the event is generated based on the provider's UTC time. |
-| `dataVersion` | string | The schema version of the data object. The publisher defines the schema version. |
-| `metadataVersion` | string | The schema version of the event metadata. Event Grid defines the schema of the top-level properties. Event Grid provides this value. |

-Here's an example of a policy state change event:
-
-```json
-[{
-    "id": "5829794FCB5075FCF585476619577B5A5A30E52C84842CBD4E2AD73996714C4C",
-    "topic": "/subscriptions/<SubscriptionID>",
-    "subject": "/subscriptions/<SubscriptionID>/resourceGroups/<ResourceGroup>/providers/<ProviderNamespace>/<ResourceType>/<ResourceName>",
-    "data": {
-        "timestamp": "2021-03-27T18:37:42.4496956Z",
-        "policyAssignmentId": "<policy-assignment-scope>/providers/microsoft.authorization/policyassignments/<policy-assignment-name>",
-        "policyDefinitionId": "<policy-definition-scope>/providers/microsoft.authorization/policydefinitions/<policy-definition-name>",
-        "policyDefinitionReferenceId": "",
-        "complianceState": "NonCompliant",
-        "subscriptionId": "<subscription-id>",
-        "complianceReasonCode": ""
-    },
-    "eventType": "Microsoft.PolicyInsights.PolicyStateChanged",
-    "eventTime": "2021-03-27T18:37:42.5241536Z",
-    "dataVersion": "1",
-    "metadataVersion": "1"
-}]

 ## Practices for consuming events
 
 Applications that handle Azure Policy events should follow these recommended practices:
