ITR/IM: Building the Framework of the National Virtual Observatory

AST0122449Inst：约翰·霍普金斯大学PI：Szalay，Alexander在这个奖项下，由约翰·霍普金斯大学领导的广泛合作将为国家虚拟天文台(NVO)建立框架和基础。建立NVO框架是朝着能够无缝整合天文学数据密集型资源的系统迈出的第一步。当完全实施后，NVO将成为天文学发现的引擎。从无线电到x射线的各种波长的太空和地面上的大规模天空测量正在启动，产生了大量高质量、不可替代的数据。这些新调查提供的科学发现的潜力是巨大的。合并使用结果数据集将产生全新的、意想不到的具有重大意义的科学结果，而单独使用这些数据集是不可能的。它们的巨大规模和复杂性需要工具和结构来发现它们内部编码的复杂现象。NVO框架将通过协调现有的各种努力来建立，并为发展尚不存在的能力提供重点。NVO将作为一个赋能和协调实体，促进进一步开发必要的工具、协议和合作，以便在未来十年充分发挥大型天文数据集的科学潜力。NVO的组成部分不仅包括档案，还包括元数据标准、标准化数据访问层、查询和计算服务以及数据挖掘应用程序。NVO的新能力对于实现已在手中或即将创建的TB/PB数据集的全部价值至关重要。快速查询多个大型星表，建立统计关联，发现新的数据模式和时间变化，以及与复杂的数值模拟对抗，这些都是通过NVO实现新科学的途径。未来的调查将有定义良好的模板，使他们能够更容易地发布他们的数据。NVO通过其丰富的内容和专门为学生、教师和公众设计的门户网站，将对广泛的科学教育和公共宣传项目产生重大影响。NVO的目标是国际范围内的，该项目将与国际社会协调其发展活动，以确保最终结果是一个全球虚拟天文台。

AST 0122449Inst : Johns Hopkins University PI: Szalay, AlexanderUnder this award, a broad collaboration led by Johns Hopkins University will establish the framework and foundation for the National Virtual Observatory (NVO). Establishing the framework for the NVO is the first step towards a system that can provide seamless integration of data-intensive resources in astronomy. When fully implemented, the NVO will serve as an engine of discovery for astronomy. Large scale surveys of the sky from space and the ground are being initiated at wavelengths from radio to x-ray, generating vast amounts of high quality, irreplaceable data. The potential for scientific discovery afforded by these new surveys is enormous. Entirely new and unexpected scientific results of major significance will emerge from the combined use of the resulting datasets, science that would not be possible from such sets used singly. Their large size and complexity require tools and structures to discover the complex phenomena encoded within them. The NVO framework will be built by coordinating the diverse efforts already in existence and provide a focus for the development of capabilities that do not yet exist. The NVO will act as an enabling and coordinating entity to foster the development of further tools, protocols, and collaborations necessary to realize the full scientific potential of large astronomical datasets in the coming decade. The components of the NVO include not only the archives, but also metadata standards, a standardized data access layer, query and computing services, and data mining applications. The new capabilities of the NVO will be essential to realize the full value of the tera/petabyte datasets that are in hand or soon to be created. Rapid querying of multiple large-scale catalogs, establishment of statistical correlations, discovery of new data patterns and temporal variations, and confrontation with sophisticated numerical simulations are all avenues for new science that will be made possible through the NVO. Future surveys will have well defined templates available to enable them to publish their data more easily. The NVO, through its rich content and special portals designed for students, teachers and the public, will have major impact on a wide range of science education and public outreach projects. The goal of the NVO is international in scope and the project will coordinate its development activities with the international community, to assure that the end result is a Global Virtual Observatory.
