--- title: classification slug: /main-concepts/metadata-standard/schemas/entity/classification/classification --- # Classification *A `Classification` entity contains hierarchical terms called tags used for categorizing and classifying data assets and other entities.* ## Properties - **`id`**: Unique identifier of this entity instance. Refer to *[../../type/basic.json#/definitions/uuid](#/../type/basic.json#/definitions/uuid)*. - **`name`**: Refer to *[../../type/basic.json#/definitions/entityName](#/../type/basic.json#/definitions/entityName)*. - **`fullyQualifiedName`**: FullyQualifiedName same as `name`. Refer to *[../../type/basic.json#/definitions/fullyQualifiedEntityName](#/../type/basic.json#/definitions/fullyQualifiedEntityName)*. - **`displayName`** *(string)*: Display Name that identifies this entity. - **`description`**: Description of the classification. Refer to *[../../type/basic.json#/definitions/markdown](#/../type/basic.json#/definitions/markdown)*. - **`version`**: Metadata version of the entity. Refer to *[../../type/entityHistory.json#/definitions/entityVersion](#/../type/entityHistory.json#/definitions/entityVersion)*. - **`termCount`** *(integer)*: Total number of children tag terms under this classification. This includes all the children in the hierarchy. Minimum: `0`. - **`updatedAt`**: Last update time corresponding to the new version of the entity in Unix epoch time milliseconds. Refer to *[../../type/basic.json#/definitions/timestamp](#/../type/basic.json#/definitions/timestamp)*. - **`updatedBy`** *(string)*: User who made the update. - **`href`**: Link to the resource corresponding to the classification. Refer to *[../../type/basic.json#/definitions/href](#/../type/basic.json#/definitions/href)*. - **`usageCount`** *(integer)*: Count of how many times the tags from this classification are used. - **`changeDescription`**: Change that lead to this version of the entity. Refer to *[../../type/entityHistory.json#/definitions/changeDescription](#/../type/entityHistory.json#/definitions/changeDescription)*. - **`deleted`** *(boolean)*: When `true` indicates the entity has been soft deleted. Default: `false`. - **`provider`**: Refer to *[../../type/basic.json#/definitions/providerType](#/../type/basic.json#/definitions/providerType)*. - **`disabled`** *(boolean)*: System classifications can't be deleted. Use this flag to disable them. Default: `false`. - **`mutuallyExclusive`** *(boolean)*: Tags under this classification are mutually exclusive. When mutually exclusive is `true` the tags from this classification are used to **classify** an entity. An entity can only be in one class - example, it can only be either `tier1` or `tier2` and not both. When mutually exclusive is `false`, the tags from this classification are used to **categorize** an entity. An entity have multiple tags simultaneously - example a customer can be `newCustomer` and `atRisk` simultaneously. Default: `"false"`. - **`domain`**: Domain the asset belongs to. When not set, the asset inherits the domain from the parent it belongs to. Refer to *[../../type/entityReference.json](#/../type/entityReference.json)*.
