CC* Storage: Robust Persistent Identification of Data (RPID)

该项目的重点是稳健、持久的数据识别，这可以极大地改进数据集的科学发现和重复使用。数据的永久标识(PID)加强了科学发现，是研究数据共享的一个重要因素。该项目创建了一个试验床来评估持久标识符的新功能。该项目的第一阶段将包括四个不同的储存库，其中包含数百万个ID，第二阶段将允许任何符合NSF资格的机构使用试验床来评估他们自己的工作。该项目将增强研究的互操作性。目前，数据有几个永久标识符选项(如数字对象标识符、句柄、档案资源密钥和统一资源名称)。现有的环境受限于解决方案多、互操作性差，以及将PID转换为数据对象的过程不一致。这个项目提供了几个新的能力：-一个研究持久标识符的新能力和互操作性的试验台，它建立在印第安纳大学网络基础设施和Amazon Web服务实例的基础上；-能够对PID类型进行原型和评估，允许研究在分布式系统中将类型彼此关联的困难和优势；以及-从PID到规范文本服务统一资源名称(CTS URN)的映射方法。将骨灰盒与手柄相结合，将允许精确的CTS骨灰盒引用能力，并具有现有广泛使用的手柄系统的灵活解析。目标是标准化PID解析的结果，允许各种PID服务在更高级别上进行互操作。

This project focuses upon robust, persistent identification of data, which could greatly improve scientific discovery and reuse of datasets. Persistent identifiers of data (PIDs) enhance scientific discovery and are an important element of research data sharing. This project creates a testbed to evaluate new capabilities for persistent identifiers. The initial stage of the project will include four diverse repositories containing millions of PIDs, and the second stage will allow any NSF-eligible institution to use the testbed to evaluate their own work. The project would enhance research interoperability.Currently, there are several persistent identifier options for data (such as Digital Object Identifiers, Handles, the Archive Resource Key, and Uniform Resource Names). The existing environment is limited by multiple solutions, weak interoperability, and procedures translating PID to data object that are inconsistent. This project provides several new capabilities: - A testbed to research new capabilities and interoperability for persistent identifiers, which builds upon Indiana University cyberinfrastructure and instances on Amazon Web Services; - The ability to prototype and evaluate PID types, allowing study of the difficulties and advantages of relating types to one another across a distributed system; and - Approaches to mapping from PIDs to Canonical Text Services Uniform Resource Names (CTS URNs). Combining URNs with Handles should allow a precise CTS URN referencing capability, with the flexible resolution of the existing widely-used Handle System.The goal is to standardize the results of PID resolution, allowing various PID services to interoperate at a higher level.
