To declare this entity in your CloudFormation template, use the following syntax:

### JSON
<a name="aws-properties-entityresolution-idmappingworkflow-idmappingworkflowinputsource-syntax.json"></a>

```
{
  "[InputSourceARN](#cfn-entityresolution-idmappingworkflow-idmappingworkflowinputsource-inputsourcearn)" : String,
  "[SchemaArn](#cfn-entityresolution-idmappingworkflow-idmappingworkflowinputsource-schemaarn)" : String,
  "[Type](#cfn-entityresolution-idmappingworkflow-idmappingworkflowinputsource-type)" : String
}
```

### YAML
<a name="aws-properties-entityresolution-idmappingworkflow-idmappingworkflowinputsource-syntax.yaml"></a>

```
  [InputSourceARN](#cfn-entityresolution-idmappingworkflow-idmappingworkflowinputsource-inputsourcearn): String
  [SchemaArn](#cfn-entityresolution-idmappingworkflow-idmappingworkflowinputsource-schemaarn): String
  [Type](#cfn-entityresolution-idmappingworkflow-idmappingworkflowinputsource-type): String
```

## Properties
<a name="aws-properties-entityresolution-idmappingworkflow-idmappingworkflowinputsource-properties"></a>

`InputSourceARN`  <a name="cfn-entityresolution-idmappingworkflow-idmappingworkflowinputsource-inputsourcearn"></a>
An AWS Glue table Amazon Resource Name (ARN) or a matching workflow ARN for the input source table.  
*Required*: Yes  
*Type*: String  
*Pattern*: `^arn:(aws|aws-us-gov|aws-cn):entityresolution:[a-z]{2}-[a-z]{1,10}-[0-9]:[0-9]{12}:(idnamespace/[a-zA-Z_0-9-]{1,255})$|^arn:(aws|aws-us-gov|aws-cn):entityresolution:[a-z]{2}-[a-z]{1,10}-[0-9]:[0-9]{12}:(matchingworkflow/[a-zA-Z_0-9-]{1,255})$|^arn:(aws|aws-us-gov|aws-cn):glue:[a-z]{2}-[a-z]{1,10}-[0-9]:[0-9]{12}:(table/[a-zA-Z_0-9-]{1,255}/[a-zA-Z_0-9-]{1,255})$`

`SchemaArn`  <a name="cfn-entityresolution-idmappingworkflow-idmappingworkflowinputsource-schemaarn"></a>
The ARN (Amazon Resource Name) that AWS Entity Resolution generated for the `SchemaMapping`.  
*Required*: No  
*Type*: String  
*Pattern*: `^arn:(aws|aws-us-gov|aws-cn):entityresolution:.*:[0-9]+:(schemamapping/.*)$`

`Type`  <a name="cfn-entityresolution-idmappingworkflow-idmappingworkflowinputsource-type"></a>
The type of ID namespace. There are two types: `SOURCE` and `TARGET`.   
The `SOURCE` contains configurations for `sourceId` data that will be processed in an ID mapping workflow.   
The `TARGET` contains a configuration of `targetId` which all `sourceIds` will resolve to.  
*Required*: No  
*Type*: String  
*Allowed values*: `SOURCE | TARGET`
