Example: Swapping the Order of a Name [MIIS]

Attribute values that are staged in the connector space might need some data transformations before they are flowed into the metaverse. Rules extensions can do these data transformations during import attribute flow. For example, business rules may require that the displayName attribute be stored in the metaverse as the combination of the first and last name of the user. However, the connected data source may provide the data in this attribute with the last name before the first name. To swap these values, you can use a rules extension.
