DocumentAttributeTarget - Amazon Kendra API Reference


The target document attribute or metadata field you want to alter when ingesting documents into Amazon Kendra.

For example, you can delete customer identification numbers associated with the documents, stored in the document metadata field called 'Customer_ID'. You set the target key as 'Customer_ID' and the deletion flag to TRUE. This removes all customer ID values in the field 'Customer_ID'. This would scrub personally identifiable information from each document's metadata.

Amazon Kendra cannot create a target field if it has not already been created as an index field. After you create your index field, you can create a document metadata field using DocumentAttributeTarget. Amazon Kendra then will map your newly created metadata field to your index field.

You can also use this with DocumentAttributeCondition.



The identifier of the target document attribute or metadata field.

For example, 'Department' could be an identifier for the target attribute or metadata field that includes the department names associated with the documents.
