# Add 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.

To add field standardization

1. Add a processor, by dragging the processor icon from the components toolbar to the canvas.

   The Add Processor dialog box opens.

2. In the Source list, click idol.nifi.

   The list of processors is filtered to those that are provided in the NiFi Ingest distribution.

3. Select the StandardizeMetadata processor and click ADD.

   The processor is added to the canvas.

4. Create a connection between the KeyViewFilterDocument processor and the StandardizeMetadata processor. Hover the mouse over the KeyViewFilterDocument processor until you see the connection icon - - and then drag the icon to the StandardizeMetadata processor.

   The Create Connection dialog box opens.

5. In the For Relationships area, select the success check box and click ADD.

   The connection appears on the canvas. NiFi automatically adds a queue between the processors.
