Universal Core

Last updated

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.

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, [1] 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:

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.

UCore 3.0

UCore Version 3.0 was released on 14 April 2012 and contains modifications approved by the UCore Council and enacted by the UCore Technical Working Group. In this release, UCore is a set of reusable data components (RDCs) for the four interrogatives, an entity-to-entity relationship model, and supporting metadata types. These RDCs can be the foundational building blocks of a custom Community of Interest (COI) vocabulary or information exchange specification. Developers who reuse the designated UCore types are expected to gain a minimum level of understandability and interoperability.

UCore 3.0 also defines a message format for Situational Awareness (SA) messages, which report upon the time and location of entities and events, often with a focus on mapping or recording location history. An instance of this SA message format will contain components which reuse the RDCs; however, a COI can still construct message payloads with the RDCs without making use of the SA message format.

In October 2012, the Department of Defense elected to move towards adopting National Information Exchange Model (NIEM). [10] This decision was formalized in a signed memorandum on 28 March 2013.

The released versions of UCore are expected to remain in place for as long as programs continue to use them, and may also support platforms that are somehow incompatible with NIEM.

Standards Used

In addition to XML, UCore incorporated the following specifications and standards:

Mandates and Recommendations

A joint 2008 DoD / ODNI Memorandum cited the availability of UCore's initial release. The Memorandum reinforced the connection between UCore and DoD 8320.2 "Data Sharing in a Net-Centric Department of Defense," and DoD 8320.2-G "Guidance for Implementing Net-Centric Data Sharing." [11]

Within the Department of Defense, the Marine Corps explicitly mandated UCore for certain applications according to U.S. Marine Corps Order 5231.3. [12]

While no OPNAV Instruction related to UCore was issued, the Navy accepted a role as DoD lead and served as overall co-lead for the federal effort. The Space and Naval Warfare Systems Command is providing engineering leadership for Navy UCore initiatives. [13]

The March 2009 acceptance of UCore by the Air Force ESC suggested a level of commitment from that service.

A letter from U.S. Strategic Command (USSTRATCOM) to the UCore Executive Steering Committee cited USSTRATCOM's sponsorship of UCore from UCore 1.0 through a UCore pilot completed in 2006. [14]

The Universal Core Working Group chartered in April 2007 included DoD lead representative Daniel Green. Green discussed the goals and challenges of the Group in a 2008 Masters thesis for the Naval Postgraduate School. While Green remained with the project through the release of UCore 2.0 in April 2009, the thesis offers additional insight into UCore tradeoffs, challenges to technical adoption, and strategies adopted to cultivate involvement of various intelligence agencies. [15]

UCore Semantic Layer (UCORE-SL)

UCORE-SL was an effort sponsored by the US Army Net-Centric Data Strategy Center of Excellence to augment the UCore Taxonomy with logical definitions for each term or relation defined within. This effort targeted UCore 2.0, which is now deprecated.

Terry Benton Bollinger is an American computer scientist who works at the MITRE Corporation. In 2003 he wrote an influential report for the U.S. Department of Defense in which he showed that free and open source software (FOSS) had already become a vital part of the United States Department of Defense software infrastructure, and that banning or restricting its use would have had serious detrimental impacts on DoD security, research capabilities, operational capabilities, and long-term cost efficiency. His report ended a debate about whether FOSS should be banned from U.S. DoD systems, and in time helped lead to the current official U.S. DoD policy of treating FOSS and proprietary software as equals. The report is referenced on the DoD CIO web site and has been influential in promoting broader recognition of the importance of free and open source software in government circles. Bollinger is also known for his activity in the IEEE Computer Society, where he was an editor for IEEE Software for six years, wrote the founding charter for IEEE Security & Privacy Magazine, and received an IEEE Third Millennium Medal for lifetime contributions to IEEE. He has written about a wide range of software issues including effective development processes, cyber security, and distributed intelligence.

In information science, an upper ontology is an ontology which consists of very general terms that are common across all domains. An important function of an upper ontology is to support broad semantic interoperability among a large number of domain-specific ontologies by providing a common starting point for the formulation of definitions. Terms in the domain ontology are ranked under the terms in the upper ontology, e.g., the upper ontology classes are superclasses or supersets of all the classes in the domain ontologies.

Established by at least February 2006, ISCO is led by the Deputy Associate Director of National Intelligence for Information Sharing and Customer Outreach, which is currently Mr. Richard A. Russell. ISCO's information sharing and customer outreach responsibilities extend beyond the United States Intelligence Community and cross the entire U.S. government.

Information exchange or information sharing means that people or other entities pass information from one to another. This could be done electronically or through certain systems. These are terms that can either refer to bidirectional information transfer in telecommunications and computer science or communication seen from a system-theoretic or information-theoretic point of view. As, "information," in this context invariably refers to (electronic) data that encodes and represents the information at hand, a broader treatment can be found under data exchange.

The National Information Exchange Model (NIEM) is the result of a collaborative effort by the United States Department of Justice and Department of Homeland Security to produce a set of common, well-defined data elements to be used for data exchange development and harmonization.

<span class="mw-page-title-main">Controlled Unclassified Information</span> US government information category

Controlled Unclassified Information (CUI) is a category of unclassified information within the U.S. Federal government. The CUI program was created by President Obama’s Executive Order 13556 to create a streamlined method for information sharing and safeguarding. The Information Security Oversight Office (ISOO) acts as the Executive Agent (EA) of the National Archives and Records Administration (NARA), and is responsible for oversight of the CUI program. The ISOO monitors the implementation of the CUI program by executive branch agencies. CUI will replace agency specific labels such as For Official Use Only (FOUO), Sensitive But Unclassified (SBU), and Law Enforcement Sensitive (LES) on new data and some data with legacy labels will also qualify as Controlled Unclassified Information. Federal contractors who handle CUI will be required to self-assess with the Cybersecurity Maturity Model Certification (CMMC) under the Cyber AB.
