Universal Core (or UCore) was a U.S. government project to facilitate sharing of intelligence and related digital content across U.S. government systems. In a (memorandum ) signed on 28 March 2013, the DoD Chief Information Officer (CIO) announced that DoD will adopt the National Information Exchange Model (NIEM) as the basis for its data exchange strategy in coordination with the NIEM Program Management Office (PMO). This DoD transition to NIEM will incorporate the ongoing efforts of DoD Universal Core (UCore) and Command and Control (C2) Core, effectively ending new development on these DoD data exchange models. The information in this article is provided for reference and background information only. ==History== Universal Core is an XML-based information exchange specification and implementation profile which provides a framework for sharing the most commonly used data concepts of Who, What, When, and Where. The purpose of UCore is to improve information sharing by defining and exchanging a small number of important, universally understandable concepts between data-sharing communities, without requiring complex mediations. The specification is modeled with an extensible XML schema, a taxonomy of high-level entities and events to categorize the concept of What, and supporting documentation and extension strategies. The final released version is v3.0. A key objective in creating UCore was to keep it simple, easy to explain, and easy to implement. UCore supports the National Information Sharing Strategy,〔(United States Intelligence Community Information Sharing Strategy ), Office of the Director of National Intelligence, 22 February 2008. Retrieved 24 September 2009.〕 a post-9/11 initiative. UCore is designed to permit "definable levels of interoperability" across user communities. To facilitate adoption, UCore looks to Communities of Interest, or knowledge domains, to encourage adoption of common vocabularies. UCore is not expected to replace complex data sharing within highly developed domains. UCore traces its roots to several predecessor initiatives: * Department of Defense Directive 8320.1, which proposed a very large data model for all DoD systems.〔(DoD Directive 8320.1 "DoD Data Administration," ) 26 September 1991, Retrieved 24 September 2009.〕 * Department of Defense Directive 8320.02 proposed to implement interoperability around communities of interest, and found success within those communities.〔(DoD Directive 8320.02 "Data Sharing in a Net-Centric Department of Defense," ) 2 December 2004. Retrieved 24 September 2009.〕 * UCore Version 1.0 was issued in October 2007 with an emphasis on sharing terrorism information and a different name. This release focused on exchanging data between Department of Defense (DoD) and the United States Intelligence Community.〔("Common Terrorism Information Sharing Standards (CTISS) Program Manual, version 1.0" ) October 2007. Retrieved 24 September 2009.〕 On 17 April 2008, a memo titled "Department of Defense and Intelligence Community Initial Release of Universal Core (UCore)" was distributed, cosigned by their respective CIOs.〔(Department of Defense and Intelligence Community Initial Release of Universal Core (UCore). ) Retrieved 24 September 2009.〕 * Cursor on Target is a simple exchange standard that is used to share information about targets. Its loosely coupled design led to multiple implementations and is used to facilitate interoperability of several systems with already fielded military software. Cursor on Target was originally developed by MITRE in 2002 in support of the U.S. Air Force Electronic Systems Center (ESC).〔Paone, Chuck. ("Hanscom to host Cursor on Target users meeting next week," ) Air Force Material Command News, 16 September 2009. Retrieved 24 September 2009.〕 Mitre first demonstrated Cursor on Target during a combined joint task force exercise in 2003, during which a Predator unmanned aircraft was able to operate in coordination with manned aircraft.〔Robbins, Doug. ("Unmanned Aircraft Operational Integration Using MITRE's Cursor on Target," ) MITRE's The Edge, Summer 2007. Retrieved 24 September 2009.〕 * UCore Version 2.0 was approved by ESC on 30 March 2009.〔(DoD CIO C2 Research Program Description, - UCore ), Assistant Secretary of Defense (Networks & Information Integration). Retrieved 24 September 2009.〕 This version added additional requirements from DoD, the Intelligence Community, Department of Justice, and the Department of Homeland Security. It incorporated concepts from Cursor on Target, and included cooperative agreements from participating agencies and communities of interest. * The first annual conference on UCore was held on the MITRE Virginia campus in September 2009.〔(UCore Users Conference Announcement - September 23-24, 2009 ), UCore.gov. Retrieved 24 September 2009.〕 The Defense Information Systems Agency was the Technical Agent for UCore, working on behalf of the DoD Chief Information Officer (DoD CIO) to create and support UCore 3.0. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Universal Core」の詳細全文を読む スポンサード リンク
