  description: >
    Fields that describe a device instance and its characteristics. 
    Data collected for applications and processes running on a (mobile) device can be enriched with these fields
    to describe the identity, type and other characteristics of the device.

    This field group definition is based on the Device namespace of the OpenTelemetry Semantic Conventions (https://opentelemetry.io/docs/reference/specification/resource/semantic_conventions/device/).

      short: The unique identifier of a device. 
      description: >
        The unique identifier of a device. The identifier must not change across application sessions but stay fixex for an instance of a (mobile) device. 

        On iOS, this value must be equal to the vendor identifier (https://developer.apple.com/documentation/uikit/uidevice/1620059-identifierforvendor).
        On Android, this value must be equal to the Firebase Installation ID or a globally unique UUID which is persisted across sessions in your application.

        For GDPR and data protection law reasons this identifier should not carry information that would allow to identify a user.
