    name: predicate
    description: The nature of the relationship between the subject and object assets.
      The predicate should be a concise, lowercase string that describes the relationship
      (e.g., "is_part_of", "is_module_of", "is_connected_to"). It should follow a
      consistent naming convention, such as using underscores to separate words and
      avoiding special characters. The maximum length of the predicate string should
      be reasonable (256 characters) to ensure clarity and maintainability. An asset
      management system should check that the length constraint is not violated and
      that the predicate follows the specified naming convention.
