Abstract0201264, Archuleta, U. California-Santa Barbara"COSMOS Virtual Data Center"This action supports the continued development of the COSMOS Virtual Strong-motion Data Center (COSMOS VDC), an unrestricted, Web-based, interactive strong ground motion data resource for the practicing earthquake engineering, emergency response, research, and other earthquake professional communities. The major goal of the Virtual Data Center (VDC) is to expand and significantly improve the accessibility and the use of all strong-motion records collected by the ever-growing number of US and international organizations. The VDC operates under the direction of The Consortium of Organizations for Strong-Motion Observation Systems (COSMOS, www.cosmos-eq.org), a public-interest nonprofit corporation for earthquake safety. Its mission is to expand and modernize significantly the acquisition and application of strong-motion data in order to increase public safety from earthquakes. The COSMOS structure enables the VDC to respond to both the organizations that collect the data and the users of the data (academic and professional), and ensures that the VDC evolves so that it remains responsive to the community of engineers, scientists and other users of strong-motion data.This action will advance the capability of the COSMOS VDC by further developing the proven concept of a virtual data center and its important role in coordinating the access and dissemination of strong-motion data. It will: 1) advance Web-based interfaces with the Advanced National Seismic System (ANSS) data management system; 2) advance methods for augmenting the existing VDC metadata database; 3) advance Web-based methods to facilitate efficient query and retrieval of a variety of event, station, and processed time history information; 4) develop Web-based methods for dissemination of information according to user selectable format, processing and visualization; 5) facilitate development of COSMOS standards for data formats and processing; 6) advance Web-based interfaces with other databases to enhance the metadata on earthquakes, recording site characteristics, and other relevant information for the VDC; 7) enhance Web-based interfaces and links for replication sites; and 8) advance Web-based interfaces with geotechnical databases.The VDC provides a very cost-effective way to leverage the data processing and management resources of all of the participating agencies and organizations. It continually develops, updates, and maintains a sophisticated parameter metadata environment in a state-of-the-art relational database. This approach provides a major step forward in improving accessibility of the data to the research, practicing, and emergency response communities for purposes of earthquake hazard mitigation.

0201264，美国加利福尼亚州阿克莱塔-圣巴巴拉“COSMOS虚拟数据中心”这一行动支持COSMOS虚拟强震数据中心(COSMOS VDC)的继续发展，COSMOS VDC是一个不受限制的、基于Web的、交互式的强地面运动数据资源，适用于地震工程、应急响应、研究和其他地震专业社区。虚拟数据中心(VDC)的主要目标是扩大并显著改善由越来越多的美国和国际组织收集的所有强震记录的可访问性和使用情况。VDC在强震观测系统组织联盟(COSMOS，www.Cosmos-eq.org)的指导下运作，该联盟是一家致力于地震安全的公益非营利性公司。它的任务是显著扩大强震数据的获取和应用，并使之现代化，以提高公众免受地震的安全。COSMOS结构使VDC能够对收集数据的组织和数据用户(学术和专业)做出回应，并确保VDC不断发展，以保持对工程师、科学家和其他强震数据用户社区的响应。这一行动将通过进一步发展虚拟数据中心的已证实概念及其在协调强震数据获取和传播方面的重要作用，提高COSMOS VDC的能力。它将：1)改进与先进国家地震系统(ANSS)数据管理系统的基于网络的接口；2)改进扩充现有VDC元数据数据库的方法；3)改进基于网络的方法，以便有效地查询和检索各种事件、台站和已处理的时间历史信息；4)根据用户可选择的格式、处理和可视化，开发基于网络的信息传播方法；5)促进制定COSMOS数据格式和处理标准；6)改进与其他数据库的基于网络的接口，以增强地震元数据、记录场地特征和其他有关信息；7)增强复制站点的基于Web的界面和链接；以及8)与岩土数据库的基于Web的高级界面。VDC提供了一种非常经济高效的方式来利用所有参与机构和组织的数据处理和管理资源。它在最先进的关系数据库中不断开发、更新和维护复杂的参数元数据环境。这一方法在改善数据对研究、实践和应急响应社区的可获得性方面向前迈出了重要的一步，以减轻地震灾害为目的。
