The Art. 2 of the UE Council conclusions of 21 May 2014 on cultural heritage as a strategic resource for a sustainable Europe (2014/C 183/08) states: “Cultural heritage consists of the resources inherited from the past in all forms and aspects—tangible, intangible and digital (born digital and digitized), including monuments, sites, landscapes, skills, practices, knowledge and expressions of human creativity, as well as collections conserved and managed by public and private bodies such as museums, libraries and archives”. Starting from this assumption, we have to rethink digital and digitization as social and cultural expressions of the contemporary age. We need to rethink digital libraries produced by digitization as cultural entities and no longer as mere dataset for enhancing fruition of cultural heritage, by defining clear and homogeneous criteria to validate and certify them as memory and sources of knowledge for future generations. By expanding R: Re-usable of the FAIR Guiding Principles for scientific data management and stewardship into R⁴: Re-usable, Relevant, Reliable and Resilient, this paper aims to propose a more reflective approach to creation of descriptive metadata for managing digital resource of cultural heritage, which can guarantee their long term preservation.

艺术。2014年5月21日UE理事会关于将文化遗产作为可持续欧洲战略资源的结论中的2（2014 / C 183/08）指出：“文化遗产包括从过去继承的各种形式和各个方面的资源，包括有形，无形和数字（天生数字和数字化），包括纪念碑，遗址，风景，技能，做法，人类创造力的知识和表现形式，以及由博物馆，图书馆和档案馆等公共和私人机构保存和管理的藏品”。从这个假设出发，我们必须重新考虑数字和数字化，将其视为当代的社会和文化表现形式。我们需要重新定义数字化产生的数字图书馆，将其作为文化实体，而不再是单纯的用于增强文化遗产成果的数据集，方法是通过定义明确且统一的标准来验证和证明它们是后代的记忆和知识源。通过扩展[R ：重-可用的的FAIR指导原则的科学数据管理和管理为[R ⁴：重-可用，相关，可靠和弹性，本文旨在提出创建描述性元数据的多个反射的方式来管理的文化数字资源遗产，可以保证其长期保存。
