# StandardizeMetadata

The `StandardizeMetadata` processor performs field standardization.

Field standardization modifies documents so that they have a consistent structure and consistent field names. You can use field standardization so that documents which originated from different connectors use the same fields to store the same type of information.

For example, documents created by the File System Connector can have a field named `FILEOWNER`. Documents created by the Documentum Connector can have a field named `owner_name`. Both of these fields store the name of the person who owns a file. Field standardization renames the fields so that they have the same name.
