摘要： A descriptive data structure provides an abstract representation of a rights management data structure such as a secure container. The abstract representation may describe, for example, the layout of the rights management data structure. It can also provide metadata describing or defining other characteristics of rights management data structure use and/or processing. For example, the descriptive data structure can provide integrity constraints that provide a way to state rules about associated information. The abstract representation can be used to create rights management data structures that are interoperable and compatible with one another. This arrangement preserves flexibility and ease of use without compromising security.

摘要翻译： 描述性数据结构提供诸如安全容器之类的权限管理数据结构的抽象表示。 抽象表示可以描述例如版权管理数据结构的布局。 它还可以提供描述或定义权限管理数据结构使用和/或处理的其他特征的元数据。 例如，描述性数据结构可以提供完整性约束，其提供了一种关于关联信息的规则的方式。 抽象表示可用于创建彼此可互操作和兼容的权限管理数据结构。 这种安排保持灵活性和易用性，而不会影响安全性。
