Modern laboratories provide unprecedented sensitivity to the many different galactic-messengers that stream through our planet by the minute: cosmic rays, light from distant galaxies, elusive neutrinos, and possibly dark matter. Combining this information with models and data from simulations provides insight into how our universe began and continues to evolve -- the scales at which objects first collapsed, the development of stars and galaxies, and the dynamics within our own galaxy. However, this data is often inaccessible: scientists within an experiment or community struggle with the complex, custom-built programs they use to access the data. And switching to a standard format is usually not an option: these data formats are designed for requirements that often do not include cross-experiment synthesis or linking. Junior scientists - let alone the public - can struggle to generate new insights from the data because the data is difficult to access, understand and analyze. The cross-cutting inquiry that could arise from clever reuse and combination of data from different experiments and simulations is rarely conducted. This project makes data accessible both within and across collaborations, providing the infrastructure to search for signals in detectors across the globe. Extending existing efforts to improve data access makes this project possible: yt is software that provides uniform access to simulation data; Kaitai is a data-description language that enables easy access to any data format; Rucio and other tools provide a standard interface that allows data downloads; and ServiceX can identify, subset and process data with little effort from the end user. Scientists have built experiments that offer an incredible wealth of information about our world. This project works to make that information accessible to everyone.Technical DescriptionThe Personal Data-Delivery infrastructure (PONDD) addresses the data challenges of existing dark matter and astrophysics experiments while requiring no changes to existing data formats. This non-invasive, no-changes-necessary support for any file format provides opportunities to expand beyond our two identified use cases, dark matter searches and astrophysics simulations, into many other data-driven science domains that rely on custom file formats. This work delivers an infrastructure that seamlessly delivers data in a well-supported format (such as Parquet) from multiple sources. To successfully deliver cross-experiment data to end users, we bring together ongoing projects from High Energy Physics and the broader NSF community; while this project will involve development of software products (yt and Kaitai) it will also include synthesis of existing investments in cyberinfrastructure and efforts to improve their long-term sustainability. This project is supported by the Office of Advanced Infrastructure in the Directorate for Computer and Information Science and Engineering and the Division of Physics in the Directorate for Mathematical and Physical Sciences.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.

现代实验室对每分钟流经我们星球的许多不同的银河信使提供了前所未有的灵敏度：宇宙射线，来自遥远星系的光，难以捉摸的中微子，可能还有暗物质。 将这些信息与模拟的模型和数据相结合，可以深入了解我们的宇宙是如何开始并继续演变的-物体首次坍塌的尺度，恒星和星系的发展以及我们自己星系内的动力学。然而，这些数据通常是无法访问的：实验或社区中的科学家与他们用来访问数据的复杂的定制程序斗争。 转换到标准格式通常不是一种选择：这些数据格式是为通常不包括交叉实验合成或链接的要求而设计的。年轻的科学家--更不用说公众了--很难从数据中产生新的见解，因为数据很难访问、理解和分析。 从不同的实验和模拟数据的巧妙重用和组合中产生的交叉调查很少进行。该项目使数据可以在协作内部和协作之间访问，为在地球仪中搜索信号提供基础设施。 扩展现有的努力，以改善数据访问使这个项目成为可能：yt是软件，提供统一的模拟数据访问; Kaitai是一种数据描述语言，可以轻松访问任何数据格式; Rucio和其他工具提供了一个标准的接口，允许数据下载;和ServiceX可以识别，子集和处理数据，而最终用户只需付出很少的努力。科学家们已经建立了实验，提供了关于我们世界的大量信息。 技术描述个人数据传输基础设施（PONDD）解决了现有暗物质和天体物理实验的数据挑战，同时不需要更改现有数据格式。 这种对任何文件格式的非侵入性、无需更改的支持提供了机会，可以扩展到我们确定的两个用例（暗物质搜索和天体物理学模拟）之外，进入许多其他依赖自定义文件格式的数据驱动科学领域。 这项工作提供了一个基础设施，可以无缝地从多个源以支持良好的格式（如Parquet）提供数据。 为了成功地向最终用户提供交叉实验数据，我们将高能物理和更广泛的NSF社区正在进行的项目结合在一起;虽然该项目将涉及软件产品（yt和Kaitai）的开发，但它还将包括对网络基础设施现有投资的综合，并努力提高其长期可持续性。该项目得到了计算机和信息科学与工程局高级基础设施办公室以及数学和物理科学局物理部的支持。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。
