Pelican: Advancing the Open Science Data Federation Platform

派力肯软件套件提供了一个平台，便于共享研究数据集。通过跨机构边界联合他们的数据集，从单个主要研究者实验室到国际合作的研究工作使他们的本地数据集可供远程客户端访问，以进行查看，缓存或处理。旗舰派力肯联合会是开放科学数据联合会（OSDF），它覆盖了整个开放科学社区。 OSDF利用嵌入在国家和国际网络中的存储，独立或与分布式计算资源结合，促进对远程数据集的有效访问，作为不同科学工作流程的一部分。遵循翻译计算机科学方法，来自三个机构的团队开发了派力肯软件套件，因此OSDF可以承担国家级数据集共享支柱的责任。派力肯的分布式计算原则使数据集提供者能够行使数据主权、访问控制、存储和网络容量保护以及使用的可观察性。派力肯客户端可以嵌入到网络浏览器、笔记本电脑或计算基础设施中。作为一个派力肯联盟，OSDF可以被视为一个“传输总线”，将客户端与使用各种后端存储技术的数据集提供商连接起来。该项目专注于与气候社区相关的数据集，并关注人工智能在研究中不断发展的作用，增强了用户体验，并为派力肯软件套件添加了新的后端。这满足了不断增长的需求，即扩大国家网络基础设施生态系统的覆盖范围，以吸引新用户和更广泛的学院和大学。这项工作也得到了国家探索云气候（NDC-C）资源的支持。该奖项反映了NSF的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。

The Pelican Software Suite provides a platform that facilitates sharing of research datasets. By federating their datasets across institutional boundaries, research endeavors ranging from single Principal Investigator laboratories to international collaborations make their local datasets accessible to remote clients for viewing, caching, or processing. The flagship Pelican federation is the Open Science Data Federation (OSDF) which has the reach of the entire open science community. Utilizing storage embedded throughout national and international networks, the OSDF facilitates, independently or in conjunction with distributed computing resources, effective access to remote datasets as part of diverse scientific workflows.Following Translational Computer Science methodology, the team from three institutions develops the Pelican Software Suite so the OSDF can carry the responsibilities of a national-scale pillar for dataset sharing. The distributed computing principles of Pelican enable dataset providers to exercise data sovereignty, access control, protection of storage and network capacity, and observability of usage. Pelican clients can be embedded in web browsers, Jupyter notebooks, or computing infrastructure. As a Pelican federation the OSDF can be viewed as a “transport bus,” connecting clients to dataset providers that use a diverse set of backend storage technologies.With a focus on datasets relevant to the climate community and attention to the evolving role of AI in research, the project enhances the user experience and adds new backends to the Pelican Software Suite. This addresses the ever-growing need to broaden the reach of the national Cyberinfrastructure ecosystem to new users and a wider spectrum of colleges and universities. This effort is also supported by National Discovery Cloud for Climate (NDC-C) resources.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.
