# 9.4.3.6 Metadata Delimiter Property

#

Step 9: Set the metadata delimiter property

In order for synchronization between the Ontology metadata tables and the CRC dimension tables to work correctly a backslash may need to be added to your metadata. Whether or not a backslash is added automatically is defined in the **Metadata delimiter (backslash)** section.

1. In the **ontology.properties** file scroll to the section called **Metadata delimiter (backslash)**.

2. Update the delimiter value for your environment.

  **METADATA delimiter (backslash)**

Ontology.terminal.delimiter=true

| Value | Description |
| --- | --- |
| true | A backslash will be added automatically to the metadata **fullpath name** if it does not already exist. |
| false | This setting will not add a backslash to the fullpath name and will provide true backward compatibility with release 1.3 |

3. Save your changes and close the file.
