1 UNCLASSIFIED 1 Universal Core Overview June 2007

2 UNCLASSIFIED 2 DoD and IC Universal Core Data Schema Constructing a universal core data schema that enables information sharing –Ways to describe when, where, what –Minimal set of terms in the core –Agreed to by DoD and Intel Community –Appropriate use of open and Federal standards –Extensible by COIs and systems as needed Strike Spiral 1 pilot is based on initial C2 common core (e.g., Task/Mission) –Incorporates universal core Increased Data Interoperability AND Agility 2 Log Common Core ** C2 Common Core ISR Common Core ** Financial Common Core ** EIE Common Core ** Universal Core COI Extensions DoD Component and IC Member Extensions ** With the exception of the C2 Common Core, the other Common Cores are notional

3 UNCLASSIFIED 3 Start with just the most common One system, info intersection is everything Two systems, much info less is common Three systems, Intersection gets smaller Universal Core starts here with a core set of common info! Typical approach: Add new information for each new system exchange... Model continues to get larger and larger and difficult to manage

4 UNCLASSIFIED 4 Mining the XML Registry for Common Elements Identified data nuggets that represent common data concepts* –Position (10199 candidate elements – 10.3%) –Quantity (10035 candidate elements – 10.1%) –Shape (7241 candidate elements – 7.3%) –Time (14161 candidate elements – 14.3%) –Type (15444 candidate elements – 15.6%) * From late believe percentages are still valid

5 UNCLASSIFIED 5 Universal Core Background DoD Directive –Attempted to define a large data model for all DoD systems to adopt –Too difficult to harmonize, implement, and scale DoD Directive –Define and implement interoperability around Communities of Interest –Success harmonizing across the community and streamlining implementation Cursor on Target –Simple, small, and powerful exchange standard –Applied loose coupling strategy –Led to numerous implementations and real warfighter capabilities Universal Core –Leverages the harmonization success of Communities of Interest –Simplicity and power of Cursor on Target –Application of commercial and DoD/IC standards

6 UNCLASSIFIED 6 Universal Core Key Principles Key Principles –Build a strong foundation Policy, Governance, Definition, and Test processes –Build Joint from the start DOD and IC communities –Harmonize across communities –Standards based –Small core with the following attributes Suitability - include only a few critical objects Simplicity - for widespread adoption Extensibility - to meet individual community needs Leveragability - of existing standards, tools, and expertise Supportability - for long-term success

7 UNCLASSIFIED 7 Governance Process – Senior Enterprise Services Governance Group (SESGG) Oversee Joint Data Strategy and Enterprise Services Implementation –Define the required measurement and control mechanisms to ensure DoD-wide and IC-wide implementation –Identify and develop necessary policy changes, including measurement and control responsibilities, to ensure consistent implementation –Establish oversight forums, as required, to enable the DoD CIO and DNI CIO to review implementation progress

8 UNCLASSIFIED 8 SESGG Members Mr. Mike Krieger, co-chair, DoD CIO Mr. John Brantley, co-chair, ADNI CIO Mr. Ron Bechtold, Army, Mr. Brian Clingerman, Navy, Mr. Kent Werner, AF Mr. David Green, USMC Ms. Bobbie Stempley, DISA Mr. Mac Townsend, DIA Mr. Dennis Wisnosky, BTA

9 UNCLASSIFIED 9 Universal Core Harmonization, Governance, Policy, Test Four Working Groups, each containing participation from all the organizations that make up the SESGG –DNI and Navy lead the methodology for describing and evolving the universal core schema –AF leads the development of Governance processes –JFCOM and Army lead the Test and Evaluation methodology –DIA and DoD lead the Policy definition

10 UNCLASSIFIED 10 Standards-based Approach GML (ISO-19136) based on the ISO series –ISO – Conceptual Schema Language –ISO – Spatial schema (geometry and topology objects) –ISO – Temporal schema (temporal geometry, topology, temporal reference systems) –ISO – Rules for application schemas –ISO – Spatial referencing by coordinates (coordinate reference systems) –ISO – Schema for coverage geometry and functions Key XML standards –W3C XML Schema –W3C XLink Security Tagging –IC-ISM (Intel Community - Info Security Marking)

11 GML Profile- Logical Subset of GML Standard GML Profile Logical Subset of GML Data Types/ Subset of gml:elements/attributes 11

12 Universal Core – What, When, Where Security Marking – IC ISM Identification – gml:feature –gml:id –gml:name & gml:description Time & Geo Bounding –gml:boundedBy Object Type – cc:type –encoded via gml:dictionary Operational Info Association – cc:link (xlink) 12

13 Security Marking – IC-ISM Approach –IC ISM tagging Required classification, ownerProducer Other optional attributes –Structure document to support tear-lines Low Releasable SA Releasable SA High Situational Awareness Info Situational Awareness Info Cross Domain Guard 13

14 Resource Linking Generic linking to other documents –To other Universal Core-based schemas –To other non-Universal Core-based schemas Utilize W3C xlink standards Utilize locator link –xlink:type – locator –Xlink:href – link to object –Xlink:role – meaning of link –Xlink:title – (String) Description of associations –Xlink:label – (String) – label for referenced object –element property (xs:string) – used to describe the hierarchical type code of referenced object 14

15 UNCLASSIFIED 15 Dictionary Dictionary – structure to define terms/vocabulary –contains dictionaryEntries where each dictionaryEntry has a definition gml:Definition –identifier – unique identifier of the term –name – synonyms for the term being defined –description – textual definition of the term –descriptionReference – link to definition of term –remarks – additional clarifying comments about the term
