SDCI NMI Improvement: OPeNDAP and NetCDF IntegrationThe integration of OPeNDAP's network technology and Unidata's netCDF scientific data access software enables the construction of data archives that provide wide-reaching benefits.Many computer applications used in advanced scientific analysis read and write data using the netCDF software package, developed by Unidata. This software package offers a number of advantages to both the developers of those applications and to the application's users. However, one thing the netCDF package lacks is a way to read from data over the Internet. OPeNDAP has developed such a capability and is working with Unidata to integrate that capability into the netCDF software. Using this new capability, applications which use netCDF can open remote files, learn about the information they contain and read data from them all without local copies of those files. Instead, the files are served like a web site where users access only those parts they need. Researchers and government laboratories can build data archives which users then access with a wide variety of existing analysis applications. The broader impacts of this project are significant. Separately, both OPeNDAP and netCDF are already widely used data infrastructure for research and education. Such infrastructure can have profound and lasting impacts on how communities use scientific data. These technologies have already advanced understanding as exemplified by their use in numerous research projects, workshops, and published papers. Combining OPeNDAP and netCDF will have a number of positive effects. Facilitating data access to large data archives helps to remove barriers and level the playing field among researchers at large institutions and individual researchers or students at small colleges or universities. Efforts at regularizing and standardizing access to data from multiple sources and disciplines encourage collaborations and new cross-disciplinary insights. Platform-independent software benefits small institutions that cannot afford special-purpose computing equipment.By facilitating the ease with which large or small data archives can be established and accessed remotely, this project helps to bring us closer to a time when scientific data are as easy as text to find and access.

SDCI NMI改进：OPeNDAP和NetCDF集成OPeNDAP的网络技术和Unidata的NetCDF科学数据访问软件的集成使数据档案的构建能够提供广泛的好处。许多用于高级科学分析的计算机应用程序使用由Unidata开发的NetCDF软件包读取和写入数据。该软件包为这些应用程序的开发人员和应用程序的用户提供了许多优势。然而，netCDF包缺乏一种通过互联网读取数据的方法。OPeNDAP已经开发了这种能力，并正在与Unidata合作，将这种能力整合到netCDF软件中。使用这一新功能，使用NetCDF的应用程序可以打开远程文件，了解它们包含的信息，并从这些文件读取数据，而不需要这些文件的本地副本。取而代之的是，这些文件就像一个网站，用户只访问他们需要的部分。研究人员和政府实验室可以建立数据档案，然后用户可以通过各种现有的分析应用程序访问这些档案。这个项目的更广泛影响是显著的。另外，OPeNDAP和netCDF都已经是广泛用于研究和教育的数据基础设施。这样的基础设施可以对社区如何使用科学数据产生深远和持久的影响。这些技术已经促进了人们的理解，它们在许多研究项目、研讨会和发表的论文中的使用就是例证。将OPeNDAP和netCDF结合起来将产生许多积极影响。促进对大型数据档案的数据访问有助于消除障碍，在大型机构的研究人员和小型学院或大学的个人研究人员或学生之间建立公平的竞争环境。对来自多个来源和学科的数据的访问进行规范化和标准化的努力鼓励合作和新的跨学科见解。独立于平台的软件使负担不起特殊用途计算设备的小型机构受益。通过促进建立和远程访问大小数据档案的简便性，该项目帮助我们更接近一个科学数据像文本一样容易查找和访问的时代。
