Universal Core

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.

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.
