Test & Evaluation Data Archival Repository (TEDAR)

TEDAR is an intuitive archival database and interfacing system that will serve as a centralized repository for results from testing and evaluation (T&E), modeling and simulation (M&S), and other analysis events sponsored by Federal agencies and other organizations in large-scale evaluation and analysis of radiation/nuclear (RN) detection instruments and procedures. The TEDAR will provide a repository for T&E event data, M&S event data, and other analysis event data, consisting of very large amounts of processed and raw structured and unstructured detection device data collected by T&E and M&S events and analyses of these data. Authorized users will be able to search for and access these data collections and retrieve data relevant to their business needs, such as performing engineering analyses and studies. This combination of raw and processed data is crucial, for example, to any replay capability to enhance algorithm sensitivity supporting the pre-deployment evaluation of algorithm enhancements based on previously collected data. TEDAR will support a variety of T&E/M&S and analysis data users and provide access to T&E/M&S data sources providing essential support to engineering, acquisition, and operational decision-making. The TEDAR will also provide each data collection and analysis organization a standard interface for sharing T&E data and lessons learned. There are a number of significant issues that must be addressed and resolved with effective solutions to successfully provide the required capabilities. The Phase I effort will be focused on developing and demonstrating highly innovative solutions to these issues that involve: (1) developing TEDAR such that it is easily customizable to meet the varying needs of a broad range of government and commercial applications beyond the immediate needs of DNDO; (2) significantly reducing the potential Operations and Maintenance (O&M) costs for a large repository system such as represented by the DNDO requirements; (3) providing a very flexible and intuitive interface for the system users; (4) providing an effective and efficient search mechanism via a rich and comprehensive set of metadata that is integrated and linked across the many disparate data collections in the repository; and (5) protecting the T&E/M&S data collections from unauthorized access, change, or corruption. Phase I will include loading of T&E data collections made available by DNDO to support development and demonstration, with a functional repository, user interface, data search and retrieval capabilities, demonstrating the innovative solutions described in this proposal. In the six months of Phase I, ArchSmart will provide a powerful system baseline with innovative solutions to the key requirements of a T&E/M&S repository, providing full confidence that the follow-on Phase II effort will result in a cost-effective and high performance system for DNDO needs, and will be well-positioned for commercial exploitation.
