Manage App assets¶
In general, these should be:
- Created in top-down order (Connection, then Application)
- Deleted in bottom-up order (Application, then Connections)1

Asset structure¶
Connection¶
An App connection requires a name
and qualifiedName
. For creation, specific settings are also required to distinguish it as an App connection rather than another type of connection. In addition, at least one of adminRoles
, adminGroups
, or adminUsers
must be provided.

- Retrieve the GUID for the admin role, to use later for defining the roles that can administer the connection.
- Build up the minimum request to create a connection.
- Provide a human-readable name for your connection, such as
production
ordevelopment
. - Set the type of connection to APP.
- List the workspace roles that should be able to administer the connection (or null if none). All users with that workspace role (current and future) will be administrators of the connection. Note that the values here need to be the GUID(s) of the workspace role(s). At least one of
adminRoles
,adminGroups
, oradminUsers
must be provided. - List the group names that can administer this connection (or null if none). All users within that group (current and future) will be administrators of the connection. Note that the values here are the name(s) of the group(s). At least one of
adminRoles
,adminGroups
, oradminUsers
must be provided. - List the user names that can administer this connection (or null if none). Note that the values here are the username(s) of the user(s). At least one of
adminRoles
,adminGroups
, oradminUsers
must be provided. - Actually call Atlan to create the connection.
- Retrieve the qualifiedName for use in subsequent creation calls. (You'd probably want to do some null checking first.)

- The
typeName
must be exactlyConnection
. - Human-readable name for your connection, such as
production
ordevelopment
. - The
connectorName
must be exactlyapp
. - The
qualifiedName
should follow the pattern:default/app/<epoch>
, where<epoch>
is the time in milliseconds at which the connection is being created. - The
category
must beAPP
. - List any workspace roles that can administer this connection. All users with that workspace role (current and future) will be administrators of the connection. Note that the values here need to be the GUID(s) of the workspace role(s). At least one of
adminRoles
,adminGroups
, oradminUsers
must be provided. - List any groups that can administer this connection. All users within that group (current and future) will be administrators of the connection. Note that the values here are the name(s) of the group(s). At least one of

must be provided. - List any users that can administer this connection. Note that the values here are the username(s) of the user(s). At least one of

must be provided.
Access policies
Atlan creates the policies that grant access to a connection, including the ability to retrieve the connection and to create assets within it, asynchronously. It can take several seconds (even up to approximately 30 seconds) before these are in place after creating the connection.
You may therefore need to wait before you'll be able to create the assets below within the connection.
To confirm access, retrieve the connection after it has been created. The SDKs' retry loops will automatically retry until the connection can be successfully retrieved. At that point, your API token has permission to create the other assets.
Note: if you are reusing an existing connection rather than creating one via your API token, you must give your API token a persona that has access to that connection. Otherwise all attempts to create, read, update, or delete assets within that connection will fail due to a lack of permissions.
Application¶
An Application requires a name
and a qualifiedName
. For creation, you also need to specify the connectionQualifiedName
of the connection for the Application. You can also provide the appId
and applicationOwnedAssets
for the asset.

- Build up the minimum request to create an Application.
- Provide a human-readable name for your Application.
- Provide the qualifiedName of the connection for this asset.
- (Optional) Provide the
appId
of this application in the source system. - (Optional) Provide the list of assets that exist in this application. Also update the individual assets to hold the qualifiedName of this application in the attribute
applicationQualifiedName
. - Actually call Atlan to create the application.

- The
typeName
must be exactlyApplication
. - Human-readable name for your asset.
- The
qualifiedName
should follow the pattern:default/app/<epoch>/<assetName>
, wheredefault/app/<epoch>
is the qualifiedName of the connection for this asset and<assetName>
is the name of this asset. - The
connectionQualifiedName
must be the exact qualifiedName of the connection for this asset. - The
connectorName
must be exactlyapp
. - (Optional) The
appId
should be id of the application in the source system. - (Optional) The Catalog assets which are present inside this application are added in
applicationOwnedAssets
attribute. - The
typeName
for this embedded reference must be the type of asset being embeded. - To complete the reference, you must include a
uniqueAttributes
object with the qualifiedName of the asset. Note: the asset must already exist in Atlan before creating the path.
Available relationships¶
Every level of the App structure is an Asset
, and can therefore be related to the following other assets.
erDiagram
Asset }o--o{ AtlasGlossaryTerm : meanings
Asset ||--o{ Link : links
Asset ||--o| Readme : readme
Asset }o--o{ Process : inputToProcesses
Asset }o--o{ Process : outputFromProcesses
AtlasGlossaryTerm¶
A glossary term provides meaning to an asset. The link terms to assets snippet provides more detail on setting this relationship.
Link¶
A link provides additional context to an asset, by providing a URL to additional information.
Readme¶
A README provides rich documentation for an asset. The add asset READMEs snippet provides more detail on setting this relationship.
Process¶
A process provides lineage information for an asset. An asset can be both an input and an output for one or more processes. The lineage snippets provide more detail on creating and working with lineage.

Although if you want to delete everything in a connection, your better avenue is the packaged connection delete utility in the UI. ↩
