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

该项目的重点是数据的鲁棒性，持久性识别，这可以大大提高科学发现和数据集的重用。 持久的数据标识符（PID）可以促进科学发现，是研究数据共享的重要组成部分。 这个项目创建了一个测试平台来评估持久标识符的新功能。 该项目的初始阶段将包括四个不同的存储库，其中包含数百万个PID，第二阶段将允许任何符合NSF资格的机构使用测试平台来评估自己的工作。 该项目将增强研究的互操作性。目前，有几个持久的数据标识符选项（如数字对象标识符，句柄，存档资源键和统一资源名称）。 现有的环境受到多种解决方案、弱互操作性以及将PID转换为不一致的数据对象的过程的限制。 该项目提供了几个新的功能：-一个测试平台，用于研究持久标识符的新功能和互操作性，它建立在印第安纳州大学的网络基础设施和亚马逊网络服务上的实例上; -原型和评估PID类型的能力，允许研究在分布式系统中将类型相互关联的困难和优点;以及-从PID映射到规范文本服务统一资源名称（CTS URN）的方法。 将URN与Handles相结合应该允许精确的CTS URN引用能力，以及现有广泛使用的Handle System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.
