To access any metadata from an asset, dataset or file, make sure the app has all the right accesses. Read more about managing Identity.

How do I...?

Create a metadata field definition

To create a metadata field, follow these steps:

  1. Create a CreateField object and fill in the necessary information.
  2. Call create_field_definition with the organization id and your CreateField object. The possible for FieldDefinitionType are:
    • BOOLEAN
    • SELECTION
    • NUMBER
    • TEXT
    • TIMESTAMP
    • URL
    • USER
create_field = CreateFieldDefinition(
  key = "my_new_field",
  display_name = "My Field",
  type = unity_cloud.assets.FieldDefinitionType.SELECT,
  accepted_values = ["value1", "value2", "value3"],
  multiselection = False
)

unity_cloud.assets.create_field_definition(org_id = "0123456", create_field = create_field)

Update a metadata field definition

To update a metadata field, follow these steps:

  1. Create an UpdateField object along with the information to update.
  2. Call update_field_definition with the organization id and your UpdateFieldobject.
update_field = UpdateFieldDefinition(
  key = "my_new_field",
  display_name = "My Field with a new name",
  accepted_values = ["value1", "value2", "value3", "value4"]
)

unity_cloud.assets.update_field_definition(org_id = "0123456", update_field = create_field)

Add accepted values to a SELECT metadata field

To add accepted values to a metadata field of type SELECT, call add_accepted_values_to_field_definition with the new values.

This action removes the necessity of calling update_field_definition with all the already existing values.


unity_cloud.assets.add_accepted_values_to_field_definition(org_id = "0123456", field_key = "my_new_field", accepted_values = ["value5", "value6"])

Remove accepted values from a SELECT metadata field

To remove accepted values to a metadata field of type SELECT, call remove_accepted_values_from_field_definition with the values you want removed.

This action removes the necessity of calling update_field_definition with the values you want to keep.


unity_cloud.assets.remove_accepted_values_from_field_definition(org_id = "0123456", field_key = "my_new_field", accepted_values = ["value5", "value6"])

Delete a metadata field definition

To delete a metadata field, call delete_field_definition with its organization id and field key.

unity_cloud.assets.delete_field_definition(org_id = "0123456", field_key = "my_new_field")

List all field definitions

To retrieve all metadata field from an organization, call list_field_definitions with the organization id and whether or not you want deleted field included in the list.

  • (Optional) Add the parameter name_sorting_order to sort the results alphabetically either in ascending or descending.
  • (Optional) Add the parameter limit_to to limit the amount of results returned. Leave it unchanged or set it to 0 to return everything.
  • (Optional) Add the parameter skip to specify the number of collection to skip in the results. Use in combination with limit_to to page through results.
fields = unity_cloud.assets.list_field_definitions(
  org_id = "0123456",
  include_deleted = False,
  name_sorting_order = SortingOrder.ASCENDING,
  limit_to = 10,
  skip = 0)

Get a field definition

To retrieve a metadata field from an organization, call get_field_definition with the organization id and the key of the field.

field = unity_cloud.assets.get_field_definition(org_id = "0123456", field_key = "my_new_field")

Manage metadata

When managing Metadata dictionaries, make sure the dictionaries have existing metadata field keys and consistent values according to their type.

For a field with a SELECT type, accepted_values can either be a string or an array of strings. This distinction depends on the value set for multiselection:

  • If set to TRUE, the accepted_values is an array of strings.
  • If set to FALSE, the accepted_values is a string.
  • Use the following code sample to create an entity:
metadata = dict()
metadata["Language"] = "C#"

asset_creation = AssetCreation(
  name = "your-asset-name",
  description = "your-asset-description",
  type = unity_cloud.assets.asset_type.MODEL_3D,
  metadata = metadata
)
  • Use the following code sample to update an entity:
    metadata = dict()
    metadata["Language"] = "C#"

    asset_update = AssetUpdate(
      name = "your-asset-name",
      metadata = metadata
    )
  • Use the following code sample to fetch an entity's metadata:
asset_metadata = unity_cloud.assets.get_asset_metadata(
  org_id = "012345",
  project_id = "1234abcd-ab12-cd34-ef56-123456abcdef",
  asset_id = "0123456789",
  keys = [])

asset_prog_language = asset_metadata["Language"]

dataset_metadata = unity_cloud.datasets.get_dataset_metadata(
  org_id = "012345",
  project_id = "1234abcd-ab12-cd34-ef56-123456abcdef",
  asset_id = "0123456789",
  dataset_id = "0123456789",
  keys = [])

file_Metadata = unity_cloud.files.get_file_metadata(
  org_id = "012345",
  project_id = "1234abcd-ab12-cd34-ef56-123456abcdef",
  asset_id = "0123456789",
  dataset_id = "0123456789",
  cloud_file_path = PurePosixPath("path/to/file.ext"),
  keys = [])
