# AWS::Bedrock::DataSource BedrockFoundationModelContextEnrichmentConfiguration
<a name="aws-properties-bedrock-datasource-bedrockfoundationmodelcontextenrichmentconfiguration"></a>

Context enrichment configuration is used to provide additional context to the RAG application using Amazon Bedrock foundation models.

## Syntax
<a name="aws-properties-bedrock-datasource-bedrockfoundationmodelcontextenrichmentconfiguration-syntax"></a>

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

### JSON
<a name="aws-properties-bedrock-datasource-bedrockfoundationmodelcontextenrichmentconfiguration-syntax.json"></a>

```
{
  "[EnrichmentStrategyConfiguration](#cfn-bedrock-datasource-bedrockfoundationmodelcontextenrichmentconfiguration-enrichmentstrategyconfiguration)" : {{EnrichmentStrategyConfiguration}},
  "[ModelArn](#cfn-bedrock-datasource-bedrockfoundationmodelcontextenrichmentconfiguration-modelarn)" : {{String}}
}
```

### YAML
<a name="aws-properties-bedrock-datasource-bedrockfoundationmodelcontextenrichmentconfiguration-syntax.yaml"></a>

```
