## Properties
<a name="aws-properties-comprehend-documentclassificationjob-inputdataconfig-properties"></a>

`InputFormat`  <a name="cfn-comprehend-documentclassificationjob-inputdataconfig-inputformat"></a>
Specifies how the text in an input file should be processed:  
+ `ONE_DOC_PER_FILE` - Each file is considered a separate document. Use this option when you are processing large documents, such as newspaper articles or scientific papers.
+ `ONE_DOC_PER_LINE` - Each line in a file is considered a separate document. Use this option when you are processing many short documents, such as text messages.
*Required*: No  
*Type*: String  
*Allowed values*: `ONE_DOC_PER_FILE | ONE_DOC_PER_LINE`  
*Update requires*: [Replacement](https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/using-cfn-updating-stacks-update-behaviors.html#update-replacement)

`S3Uri`  <a name="cfn-comprehend-documentclassificationjob-inputdataconfig-s3uri"></a>
The Amazon S3 URI for the input data. The URI must be in same Region as the API endpoint that you are calling. The URI can point to a single input file or it can provide the prefix for a collection of data files.   
For example, if you use the URI `S3://bucketName/prefix`, if the prefix is a single file, Amazon Comprehend uses that file as input. If more than one file begins with the prefix, Amazon Comprehend uses all of them as input.
