Manage data domains

Create new data domain

To create a new data domain:

Java

Create a data domain

DataDomain domain = DataDomain.creator("Marketing") // (1)
    .assetIcon(AtlanIcon.ROCKET) // (2)
    .assetThemeHex(AtlanMeshColor.MAGENTA)
    .build(); // (3)
AssetMutationResponse response = domain.save(client); // (4)

1. You must provide a human-readable name for your data domain.
2. You can chain onto the creator any other enrichment, for example choosing a different icon or color to represent the domain.
3. You then need to build the object.
4. You can then save() the object you've built to create the new data domain in Atlan. Because this operation will persist the asset in Atlan, you must provide it an AtlanClient through which to connect to the tenant.

Python

Create a data domain

from pyatlan.client.atlan import AtlanClient
from pyatlan.model.assets import DataDomain
from pyatlan.model.enums import AtlanIcon, AtlanMeshColor

client = AtlanClient()

domain = DataDomain.creator(
    name="Marketing",  # (1)
)
domain.asset_icon = AtlanIcon.ROCKET  # (2)
domain.asset_theme_hex = AtlanMeshColor.MAGENTA

response = client.asset.save(domain)  # (3)

1. You must provide a human-readable name for your data domain.
2. You can apply any other enrichment, for example choosing a different icon or color to represent the domain.
3. You can then save() the object to create the new data domain in Atlan.

Kotlin

Create a data domain

val domain = DataDomain.creator("Marketing") // (1)
    .assetIcon(AtlanIcon.ROCKET) // (2)
    .assetThemeHex(AtlanMeshColor.MAGENTA)
    .build() // (3)
val response = domain.save(client) // (4)

1. You must provide a human-readable name for your data domain.
2. You can chain onto the creator any other enrichment, for example choosing a different icon or color to represent the domain.
3. You then need to build the object.
4. You can then save() the object you've built to create the new data domain in Atlan. Because this operation will persist the asset in Atlan, you must provide it an AtlanClient through which to connect to the tenant.

Raw REST API

POST /api/meta/entity/bulk

{
  "entities": [
    {
      "typeName": "DataDomain", // (1)
      "attributes": {
        "name": "Marketing", // (2)
        "assetIcon": "PhRocket", // (3)
        "assetThemeHex": "#F34D77",
        "qualifiedName": "default/domain/marketing" // (4)
      }
    }
  ]
}

1. The typeName must be exactly DataDomain.
2. Human-readable name for your data domain.
3. You can specify other enrichment, for example choosing a different icon or color to represent the domain.
4. The qualifiedName should follow the pattern: default/domain/<lowerCamelCaseName>.

Create new subdomain

To create a new subdomain:

Java

Create a subdomain

DataDomain sub = DataDomain.creator("Social Marketing", // (1)
    DataDomain.refByQualifiedName("default/domain/marketing")) // (2)
    .build(); // (3)
AssetMutationResponse response = sub.save(client); // (4)

1. You must provide a human-readable name for your data domain.
2. To create subdomain, you must provide the parent domain with at least its qualifiedName.
3. You can chain on other enrichment, like above, but ultimately then need to build the object.
4. You can then save() the object you've built to create the new data subdomain in Atlan. Because this operation will persist the asset in Atlan, you must provide it an AtlanClient through which to connect to the tenant.

Python

Create a subdomain

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

client = AtlanClient()

sub_domain = DataDomain.creator(
    name="Social Marketing",  # (1)
    parent_domain_qualified_name="default/domain/marketing",  # (2)
)
response = client.asset.save(sub_domain)

1. Human-readable name for your data domain.
2. To create subdomain, you must provide the parent domain qualifiedName.

Kotlin

Create a subdomain

val sub = DataDomain.creator("Social Marketing",  // (1)
    DataDomain.refByQualifiedName("default/domain/marketing")) // (2)
    .build() // (3)
val response = sub.save(client) // (4)

1. You must provide a human-readable name for your data domain.
2. To create subdomain, you must provide the parent domain with at least its qualifiedName.
3. You can chain on other enrichment, like above, but ultimately then need to build the object.
4. You can then save() the object you've built to create the new data subdomain in Atlan. Because this operation will persist the asset in Atlan, you must provide it an AtlanClient through which to connect to the tenant.

          }
        }
      }
    }
  ]
}

1. The typeName must be exactly DataDomain.
2. Human-readable name for your data sub-domain.
3. The qualifiedName should follow the pattern: <parentQualifiedName>/domain/<lowerCamelCaseName>.
4. You must provide the qualifiedName of the parent domain.
5. Provide a superDomainQualifiedName for the data domain under which you want to create this sub-domain. If creating a sub-domain under another sub-domains (ie. nested sub-domains), this should be the qualified name of the root-level domain.
6. You must also specify a relationship to the parent domain, in this example through its qualifiedName.

Retrieve data domain

To retrieve a data domain by its human-readable name:

Java

Retrieve a data domain by its human-readable name

DataDomain domain = DataDomain.findByName( // (1)
    client, "marketing", List.of("certificateStatus")
).get(0);

1. Use DataDomain.findByName() method to retrieve a data domain by its human-readable name:

   • client through which to access a tenant.
   • name of the data domain.
   • (optional) a list of attributes to retrieve for the data domain, for example certificateStatus.

Python

Retrieve a data domain by its human-readable name

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

client = AtlanClient()

domain = client.asset.find_domain_by_name( # (1)
    name="marketing",
    attributes=["certificateStatus"]
)

assert domain
assert domain.certificate_status

1. Use client.asset.find_domain_by_name() method to retrieve a data domain by its human-readable name:

   • name of the data domain.
   • (optional) a list of attributes to retrieve for the data domain, for example certificateStatus.

Kotlin

Retrieve a data domain by its human-readable name

val domain = DataDomain.findByName( // (1)

1. Use DataDomain.findByName() method to retrieve a data domain by its human-readable name:

   • client through which to access a tenant.
   • name of the data domain.
   • (optional) a list of attributes to retrieve for the data domain, for example certificateStatus.

Update data domain

To update a data domain or subdomain:

Java

Update a data domain

        "Marketing")
    .userDescription("Now with a description!") // (2)
    .build(); // (3)

2. You can chain onto the updater any other enrichment, for example changing the domain's description.
3. You then need to build the object.
4. You can then save() the object you've built to update the data domain in Atlan. Because this operation will persist the asset in Atlan, you must provide it an AtlanClient through which to connect to the tenant.

Python

Update a data domain

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

client = AtlanClient()

data_domain = DataDomain.updater( # (1)
    qualified_name="default/domain/marketing", # (2)
    name="Marketing", # (3)
)
data_domain.user_description = "Now with a description!" # (4)

response = client.asset.save(data_domain)  # (5)

1. Use the updater() method to update a data domain.
2. You must provide the qualifiedName of the data domain.
3. You must provide the name of the data domain.
4. You can then add on any other updates, such as changing the user description of the data domain.
5. To update the data domain in Atlan, call the save() method with the object you've built.

Kotlin
