# AWS::Glue::Classifier
<a name="aws-resource-glue-classifier"></a>

The `AWS::Glue::Classifier` resource creates an AWS Glue classifier that categorizes data sources and specifies schemas. For more information, see [Adding Classifiers to a Crawler](https://docs.aws.amazon.com/glue/latest/dg/add-classifier.html) and [Classifier Structure](https://docs.aws.amazon.com/glue/latest/dg/aws-glue-api-crawler-classifiers.html#aws-glue-api-crawler-classifiers-Classifier) in the *AWS Glue Developer Guide*. 

## Syntax

## Return values
<a name="aws-resource-glue-classifier-return-values"></a>

### Ref
<a name="aws-resource-glue-classifier-return-values-ref"></a>

When you pass the logical ID of this resource to the intrinsic `Ref` function, `Ref` returns the classifier name.

For more information about using the `Ref` function, see [https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html](https://docs.aws.amazon.com/AWSCloudFormation/latest/TemplateReference/intrinsic-function-reference-ref.html).
