Enhanced Connector Enhanced connectors add extended capabilities and require a separate entitlement in addition to your Alation platform license.

The Purview File enhanced connector is used to catalog Purview assets in Alation. It extracts Purview objects such as collections, folders, files, and schemas. After extraction, users can search for and find Purview objects and curate the corresponding catalog object pages.

The connector is distributed as a .zip package that you upload and install in the Alation application. You can download the latest connector package from the Alation Customer Portal (Customer Portal > Connectors).
