MetadataURL
URL Fields provide a single free-form text entry for a property.
The form will attempt to validate that the URL is formatted properly. This is a loose validation. If the URL is valid, then the LinkOut icon 
will activate. When the user clicks on the icon, the default browser will open and display the URL's page.
You can optionally use Dependencies to set one or more Fields that must have data before a user can enter data in this Field. This Field will be disabled until there is a value present in the Field you specify in Dependencies. Learn more about Dependencies
- To configure, choose one or more Fields from the Dependencies dropdown in the Advanced tab. The dropdown will display all currently defined Fields, so you will need to define Fields before you can use them as Dependencies for other Fields.
