This guide is for everyone who seeks advice for creating stable, secure, and persistent Uniform Resource Identifiers (URIs) in order to publish their data in accordance to the FAIR principles. The use case does not matter. It could range from publishing the results of a small research project to a large knowledge graph at a big corporation. The FAIR principles apply equally and this is why it is important to put extra thought into the URI selection process. The title aims to extend the tradition of "Cool URIs don't change" and "Cool URIs for the Semantic Web". Much has changed since the publication of these works and we would like to revisit some of the principles. Many still hold today, some had to be reworked, and we could also identify new ones

翻译：本指南面向所有希望依据FAIR原则发布数据、需要创建稳定、安全且持久统一资源标识符（URI）的实践者。具体应用场景不受限制，既可以是小型科研项目成果的发布，也可以是大型企业级知识图谱的构建。FAIR原则在不同规模场景中具有同等适用性，这正是需要审慎设计URI选择策略的重要原因。本指南标题旨在延续"Cool URIs don't change"与"Cool URIs for the Semantic Web"的学术传统。自这些经典文献发表以来，技术环境已发生深刻变革，我们有必要重新审视部分设计原则：其中许多原则至今依然有效，部分原则需进行适应性调整，同时我们也识别出若干新兴设计准则。
