Mapping Navigator metadata to Atlas
You must validate the Navigator to Apache Atlas transition by reviewing the list of metadata mapping and its types transitioned from the Navigator.
Use this topic as a checklist to help you validate the transition of metadata from Navigator to Atlas.
User-supplied metadata mapping
The following user-supplied metadata is transitioned to Atlas, including definitions and
assignments to entities. Enumerations defined in Navigator are created as instances of the
enumeration type in Atlas.

Policy mapping
Navigator policies provided the ability to apply metadata to Navigator entities. They do
not have an equivalent function in Atlas and are not transitioned. You may be able to
implement similar functionality through data profilers in the Data Catalog.
You can create a report of Navigator policies using the Navigator API, for example, use a
GET call to the
/policy
API:
curl -X GET "<navigator host>:<port>/api/v14/policy" -u <username>:<password>
Technical metadata mapping
The transition process maps all the needed technical metadata for entities from Navigator to be represented in Atlas. There are some instances where the transition has to convert data from one type to another or generate new content to conform to the Atlas data model. The details of the entity mapping are exhaustively described in the Atlas technical metadata transition reference.
