Manage tags and tagged items. Data assets are tagged at the resource level and the field level. These tags may be provided by authorized users or suggested by the Data Catalog's discovery engine. |
| 5 | Manage Data Objects | Search and find assets created by curated and studied data to start a project. Data objects are assets formed by joining several other assets and represent the most curated and studied data. |

At the bottom of the Home page are the My Information and Continue Working cards.
The My Information card lists your user information, such as the roles assigned to you and any pre-defined filters for your search dimensions.
The Continue Working card lists the number of your new or unread notifications, the last five searches you performed, and up to the last five resources you worked during your last login.
Role-based access control
Role-based access permissions control access to the Lumada Data Catalog.
Data Catalog provides two pre-defined roles, Guest and System Admin, with limited privileges. Users with the System Admin role can create custom roles with access to more Data Catalog assets and features.
If your user role is a pre-defined role, you are configured for browse-only access to virtual folders and tag domains. With a pre-defined user role, you cannot customize or override search dimensions or custom roles.
Roles and permissions
Lumada Data Catalog provides two predefined roles, Guest and System Admin. These have limited privileges, just enough to get Data Catalog set up started. Data Catalog custom roles, derived from basic roles created by the System Admin user, can participate in Role Based Access Control with customized access to Data Catalog assets and features.
Resource read access control
While pre-defined roles control the curation capabilities of data, role-based access provides finer control over the visibility of resource metadata based on the user role.
Data Catalog provides the following levels of access control:
NATIVE (N)
When the Read Access permission is set to this level, data visibility is controlled by the native system. The system permissions of the individual resource control the user's data access.
For example, users with the FinanceAnalyst role who are granted Native read access in Data Catalog cannot view the metadata of the resources unless they are also granted permission in the native system, even when those virtual folders are assigned to them in the Data Catalog.
METADATA (M)
When the Read Access permission is set to this level, users can view the metadata for the resource in Data Catalog, even when the system permissions of the resource deny them access to the data.
When a user is assigned multiple roles, the most trusted read-level access prevails. The user can view the metadata of all resources within the virtual folders assigned to the role. For example, if a user is assigned both the MarketingAdmin and SalesSteward roles, and the MarketingAdmin role is assigned NATIVE read access to a resource while the SalesSteward role is assigned METADATA read access to the same resource, then the user can view the metadata of the resource within the virtual folders assigned to this role.
