在 ODRL 2. 0 版权描述语言的基础上,提出了一种适用于数字印刷企业资产版权保护的许可证模型,并设计了一种基于 ODRL 2. 0 许可证的数字印刷版权保护模型。 分析了 ODRL 2. 0 的核心模型、抽象模型、补偿模型和 XML 编码,给出了一个适用于数字印刷企业的许可证实例和 XML 编码。 分析了现有的资产版权保护模型的缺陷和不足,提出了侧重于许可证文件应用性的扩充和改进模型。 该模型扩充了版权保护模型,提高了实用性和安全性。

On the basis of copyright description language ODRL 2. 0, a novel asset copyright protection license model for digital printing business was proposed; a digital print copyright protection model was designed based on ODRL 2 license. ODRL 2 core model, abstract model, remedy model and XML encoding was analyzed, and a license instance and the XML encoding suitable for digital printing business was provided. The defects and deficiencies in existing asset copyright protection model were analyzed, and an application-oriented expansion and advanced model focus on the license file was proposed. The model expanded the original copyright protection model, improved usability and security.
