class DataItem(proto.Message):
    r"""A piece of data in a Dataset. Could be an image, a video, a
    document or plain text.

    Attributes:
        name (str):
            Output only. The resource name of the
            DataItem.
        create_time (google.protobuf.timestamp_pb2.Timestamp):
            Output only. Timestamp when this DataItem was
            created.
        update_time (google.protobuf.timestamp_pb2.Timestamp):
            Output only. Timestamp when this DataItem was
            last updated.
        labels (Sequence[google.cloud.aiplatform_v1.types.DataItem.LabelsEntry]):
            Optional. The labels with user-defined
            metadata to organize your DataItems.
            Label keys and values can be no longer than 64
            characters (Unicode codepoints), can only
            contain lowercase letters, numeric characters,
            underscores and dashes. International characters
            are allowed. No more than 64 user labels can be
            associated with one DataItem(System labels are
            excluded).

            See https://goo.gl/xmQnxf for more information
            and examples of labels. System reserved label
            keys are prefixed with
            "aiplatform.googleapis.com/" and are immutable.
        payload (google.protobuf.struct_pb2.Value):
            Required. The data that the DataItem represents (for
            example, an image or a text snippet). The schema of the
            payload is stored in the parent Dataset's [metadata
            schema's][google.cloud.aiplatform.v1.Dataset.metadata_schema_uri]
            dataItemSchemaUri field.
        etag (str):
            Optional. Used to perform consistent read-
            odify-write updates. If not set, a blind
            "overwrite" update happens.
