Purposes

Purposes are a way of curating assets by a business area, or to further protect particularly sensitive data.

List purposes

1.4.0 1.1.0

To retrieve a listing of purposes, run a search and page the results:

Java Python Kotlin Raw REST API

Purpose.select() // (1)
    .stream() // (2)
    .filter(a -> a instanceof Purpose) // (3)
    .forEach(p -> { // (4)
        log.info("Purpose: {}", p);
    });

1. To start building up a query specifically for purposes, you can use the select() convenience method on Purpose itself.
2. The search will only run when you call the stream() method, which will then lazily-load each page of results into a stream.
3. (Optional) You can do any other operations you might do on a stream, such as filtering the results to ensure they are of a certain type.
4. This is the pattern for iterating through all results (across pages) covered in the Searching for assets portion of the SDK documentation.

from pyatlan.client.atlan import AtlanClient
from pyatlan.model.assets import Purpose
from pyatlan.model.fluent_search import CompoundQuery, FluentSearch

client = AtlanClient()
search_request = (
    FluentSearch()  # (1)
    .where(CompoundQuery.active_assets())
    .where(CompoundQuery.asset_type(Purpose))  # (2)
).to_request()  # (3)
results = client.asset.search(search_request) # (4)
for asset in results: # (5)
    if isinstance(asset, Purpose):
        # Do something with the Purpose

1. Begin building up a query combining multiple conditions.
2. Ensure that we include only objects of type Purpose.
3. Build this query into a new search request.
4. Run the search.
5. Page through the results (each asset in the results will be a purpose).

Purpose.select() // (1)
    .stream() // (2)
    .filter { it is Purpose } // (3)
    .forEach { // (4)
        log.info { "Purpose: $it" }
    }

1. To start building up a query specifically for purposes, you can use the select() convenience method on Purpose itself.
2. The search will only run when you call the stream() method, which will then lazily-load each page of results into a stream.

              }
            }

    },
    "track_total_hits": true
  },
  "suppressLogs": true,
  "showSearchScore": false,
  "excludeMeanings": false,
  "excludeClassifications": false
}

1. Begin building up a query combining multiple conditions.
2. Ensure that we include only objects of type Purpose.

Create a purpose

1.4.0 1.0.0

To create a new purpose:

Java Python Kotlin Raw REST API

Purpose toCreate = Purpose.creator( // (1)
        "Known Issues", // (2)
        List.of("Issue")) // (3)
    .build();
AssetMutationResponse response = toCreate.save(); // (4)
Purpose purpose = (Purpose) response.getCreatedAssets().get(0); // (5)

1. Like other builder patterns in the SDK, the creator() method ensures all required information is provided for the purpose.
2. You must provide a name for the purpose.
3. You must provide a list of the tags that are included in the purpose.
4. To create the purpose in Atlan, call the save() method against the object you've built.
5. You can then retrieve the resulting details of the created purpose from the response (you may of course want to do some type checking first).

from pyatlan.client.atlan import AtlanClient
from pyatlan.model.assets import Purpose

client = AtlanClient()
to_create = Purpose.create( # (1)
    name="Data Assets", # (2)
    atlan_tags=["Issue"]) # (3)
response = client.asset.save(to_create) # (4)
p = response.assets_created(asset_type=Purpose)[0] # (5)

1. Like other builder patterns in the SDK, the create() method ensures all required information is provided for the purpose.
2. You must provide a name for the purpose.
3. You must provide a list of the Atlan tags that are included in the purpose.
4. To create the purpose in Atlan, call the save() method with the object you've built.
5. You can then retrieve the resulting details of the created purpose from the response.

val toCreate = Purpose.creator( // (1)
        "Known Issues", // (2)
        listOf("Issue")) // (3)
    .build()
val response = toCreate.save() // (4)
val purpose = response.createdAssets[0] as Purpose // (5)

1. Like other builder patterns in the SDK, the creator() method ensures all required information is provided for the purpose.
2. You must provide a name for the purpose.
3. You must provide a list of the tags that are included in the purpose.
4. To create the purpose in Atlan, call the save() method against the object you've built.
5. You can then retrieve the resulting details of the created purpose from the response (you may of course want to do some type checking first).

{
  "entities": [ // (1)
    {
      "typeName": "Purpose", // (2)
      "attributes": {
        "displayName": "Known Issues", // (3)
        "purposeClassifications": [
          "jRr7KmCSPliWQQSVK6dqTc" // (4)
        ],
        "isAccessControlEnabled": true, // (5)
        "qualifiedName": "Known Issues", // (6)
        "name": "Known Issues" // (7)
      }
    }
  ]
}

1. Wrap the purpose definition in an entities array.
2. Ensure the type of each nested object is exactly Purpose.
3. Use the displayName to provide the name for the purpose as you want it to appear in the UI.
4. You must specify at least one Atlan tag in the purposeClassifications array. Note that this needs to use the Atlan-internal hashed-string representation of the Atlan tag.
5. Ensure you explicitly set the access control to enabled when creating it.
6. You must provide a qualifiedName for the purpose, although this will be generated and overwritten by the back-end
7. You must provide a name for the purpose, although this will also be normalized by the back-end so will be slightly different once created.

Retrieve a purpose

1.4.0 1.0.0

To retrieve a purpose by its name:

Java Python Kotlin Raw REST API

List<Purpose> list = Purpose.findByName("Known Issues"); // (1)

1. The findByName() method handles searching for the purpose based on its name, which could therefore return more than one result. You can also (optionally) provide a second parameter with a list of attributes to retrieve for each purpose.

from pyatlan.client.atlan import AtlanClient

client = AtlanClient()
result = client.asset.find_purposes_by_name("Known Issues") # (1)

1. The asset.find_purposes_by_name() method handles searching for the purpose based on its name, which could therefore return more than one result.

val list = Purpose.findByName("Known Issues") // (1)

1. The findByName() method handles searching for the purpose based on its name, which could therefore return more than one result. You can also (optionally) provide a second parameter with a list of attributes to retrieve for each purpose.

{
  "dsl": {
    "query": {
      "bool": {
        "filter": [
          {
            "term": {
              "__state": {
                "value": "ACTIVE"
              }
            }
          },
          {
            "term": {
              "__typeName.keyword": {
                "value": "Purpose" // (1)
              }
            }
          },
          {
            "term": {
              "name.keyword": {
                "value": "Known Issues" // (2)
              }
            }
          }
        ]
      }
    },
    "track_total_hits": true
  },
  "suppressLogs": true,
  "showSearchScore": false,
  "excludeMeanings": false,

Add policies to a purpose

Do not add policies in bulk

Be careful to only add policies one-by-one to a purpose. While the SDKs will allow you to add them in bulk, currently this results in a purpose where only the final policy in the batch is active at the end of the operation.

Add a metadata policy

1.4.0 1.0.0

To add a metadata policy to a purpose:

Java Python Kotlin Raw REST API

AuthPolicy metadata = Purpose.createMetadataPolicy( // (1)

        AuthPolicyType.ALLOW, // (4)
        Set.of(PurposeMetadataAction.READ), // (5)
        null, // (6)
        null, // (7)
        true) // (8)
    .build();
AssetMutationResponse response = metadata.save(); // (9)

1. Use the createMetadataPolicy() method to start building a metadata policy with the minimal required information.
2. You must give the policy a name.
3. You must provide the GUID of the purpose to attach this policy to.
4. Specify the type of policy (granting or denying the actions specified next).

5. Specify the set of permissions you want to allow (or deny) in this policy.

   To include all permissions

   If you want to include all permissions, you can simply use Arrays.asList(PurposeMetadataAction.values()).

6. (Optional) Specify the internal names of groups you want the policy to apply to. At least this or the list of users, or all users must be provided.

7. (Optional) Specify the usernames of users you want the policy to apply to. At least this or the list of groups, or all users must be provided.
8. (Optional) Apply this policy to all users. If this is set to true it will override the previous two parameters, or if false one of the previous two parameters (users or groups) must be specified.
9. To then add the policy to the purpose in Atlan, call the save() method against the policy object you've built.

from pyatlan.client.atlan import AtlanClient
from pyatlan.model.assets import Purpose
from pyatlan.model.enums import AuthPolicyType, PurposeMetadataAction

6. Specify either the internal names of groups, the usernames of users, or this all_users option to control who you want the policy to apply to. At least one of these must be provided.
7. To then add the policy to the purpose in Atlan, call the save() method with the policy object you've built.

val metadata = Purpose.createMetadataPolicy( // (1)
        "Simple read access",  // (2)
        "3886a92c-2510-40ea-a14d-803d7ac1616b",  // (3)

5. Specify the type of policy (granting or denying the actions specified next).
6. You must use a policy service name of atlas_tag.
7. You must give the policy a name.
8. You must give the policy itself a qualifiedName, although this will be overwritten by a generated value by the back-end.

9. Specify the set of permissions you want to allow (or deny) in this policy.

   To review available permissions

   To review the available permissions, see the SDKs — for example, the PurposeMetadataAction enum in the Java SDK.

10. Use an embedded accessControl object to define the purpose to attach this policy to.

11. The embedded type name of the accessControl object must be exactly Purpose.
12. You must provide the GUID of the purpose to attach this policy to.
13. You must set the policy resource category to TAG.
14. You must specify at least one username in a policyUsers array or one internal group name in a policyGroups array. The special group public covers all users.

Add a data policy

1.4.0 1.0.0

To add a data policy to a purpose:

5. Specify either the names of internal groups, the usernames of users, or this all_users option to control who you want the policy to apply to. At least one of these must be provided.
6. If you set the policy type to DATAMASK, you also need to set the type of masking you want to apply.
7. To then add the policy to the purpose in Atlan, call the save() method with the policy object you've built.

val data = Purpose.createDataPolicy( // (1)
        "Mask the data",  // (2)
        "3886a92c-2510-40ea-a14d-803d7ac1616b",  // (3)
        AuthPolicyType.DATA_MASK,  // (4)
        null,  // (5)
        null,  // (6)
        true) // (7)
    .policyMaskType(DataMaskingType.HASH) // (8)
    .build()
val response = data.save() // (9)

1. Use the createDataPolicy() method to start building a data policy with the minimal required information.
2. You must give the policy a name.
3. You must provide the GUID of the purpose to attach this policy to.
4. Specify the type of policy (granting, denying or masking the data of assets with the tags in the purpose).
5. (Optional) Specify the names of internal groups you want the policy to apply to. At least this or the list of users, or all users must be provided.
6. (Optional) Specify the usernames of users you want the policy to apply to. At least this or the list of groups, or all users must be provided.
7. (Optional) Apply this policy to all users. If this is set to true it will override the previous two parameters, or if false one of the previous two parameters (users or groups) must be specified.
8. If you set the policy type to DATA_MASK, you also need to chain on the type of masking you want to apply.
9. To then add the policy to the purpose in Atlan, call the save() method against the policy object you've built.

        "policyGroups": [
          "public" // (15)
        ]
      }
    }
  ]
}

1. Wrap all updates in an entities array.
2. For each embedded object, use the exact type name AuthPolicy.
3. You must use a policy subcategory of metadata.
4. You must use a policy category of purpose.
5. Specify the type of policy (granting, denying or masking the data of assets with the tags in the purpose).

6. If you set the policy type to dataMask, you also need to set the type of masking you want to apply.

   To review available masking options

   To review the available masking options, see the SDKs — for example, the DataMaskingType enum in the Java SDK.

7. You must use a policy service name of atlas_tag.

8. You must give the policy a name.
9. You must give the policy itself a qualifiedName, although this will be overwritten by a generated value by the back-end.
10. Specify the set of permissions you want to allow (or deny) in this policy. A data policy for a purpose can only allow or deny select permissions.
11. Use an embedded accessControl object to define the purpose to attach this policy to.
12. The embedded type name of the accessControl object must be exactly Purpose.
13. You must provide the GUID of the purpose to attach this policy to.
14. You must set the policy resource category to TAG.
15. You must specify at least one username in a policyUsers array or one internal group name in a policyGroups array. The special group public covers all users.

List policies in a purpose

1.4.0 1.1.0

To list all the policies in a purpose:

Java Python Kotlin Raw REST API

Purpose.select() // (1)
    .where(Purpose.NAME.eq("Known Issues")) // (2)
    .includeOnResults(Purpose.POLICIES) // (3)
    .includeOnRelations(AuthPolicy.NAME) // (4)
    .includeOnRelations(AuthPolicy.POLICY_TYPE)
    .includeOnRelations(AuthPolicy.POLICY_ACTIONS)
    .includeOnRelations(AuthPolicy.POLICY_USERS)
    .includeOnRelations(AuthPolicy.POLICY_GROUPS)
    .stream() // (5)
    .filter(a -> a instanceof Purpose)
    .forEach(p -> { // (6)
        Set<IAuthPolicy> policies = ((Purpose) p).getPolicies();
        for (IAuthPolicy policy : policies) {
            // Do something with each policy
        }
    });

1. Start by selecting a purpose, here using a FluentSearch-based approach.
2. You can select the purpose by whatever you like, in this example we are selecting based on its name.
3. Include the policies for the purpose as part of the search results.
4. Include all the attributes you want about each policy on the relations of the search results. Here we are including the name, type, actions and users controlled by each policy.
5. You can then directly stream the results of the search.
6. For each result of the search (itself a Purpose), you can then retrieve its policies and iterate through them.

from typing import cast

from pyatlan.client.atlan import AtlanClient
from pyatlan.model.assets import AuthPolicy, Purpose
from pyatlan.model.fluent_search import FluentSearch

client = AtlanClient()
request = (
    FluentSearch()

response = client.asset.search(request)  # (6)
for p in response:  # (7)
    policies = cast(Purpose, p).policies
    for policy in policies:
        # Do something with each policy

1. Start by selecting a purpose, here using a FluentSearch-based approach.

3. Include the policies for the purpose as part of the search results.
4. Include all the attributes you want about each policy on the relations of the search results. Here we are including the name, type, actions and users controlled by each policy.
5. You can then translate the FluentSearch into a search request.
6. Run a search using the search request.
7. For each result of the search (itself a Purpose), you can then retrieve its policies and iterate through them.

Purpose.select() // (1)
    .where(Purpose.NAME.eq("Known Issues")) // (2)
    .includeOnResults(Purpose.POLICIES) // (3)
    .includeOnRelations(AuthPolicy.NAME) // (4)

    .stream() // (5)
    .filter { it is Purpose }
    .forEach { // (6)
        val policies = (it as Purpose).policies

Personalize the purpose

1.4.0 1.0.0

To personalize which details to show for assets within a purpose:

Java Python Kotlin Raw REST API

Purpose toUpdate = Purpose.updater( // (1)
