        What is an Ontology
•   Metaphysics that studies the nature of existence

•   An ontology is a description (like a formal
    specification of a program) of the concepts and
    relationships that can exist for an agent or a
    community of agents

        C4ISR Data Ontology
    A specification mechanism for conceptualization
    of C4ISR interoperability data

          Ontologies Enable
          The Semantic Web
• Interweave concepts & their representation
• Capture semantics describing processes
  within domains
• W3C languages provide common syntax
  for cross-domain information exchange

                                               Page 12
 Current Systems Are Not Web-Enabled
• Support tasks, not processes
  – Local optimization (vertical integration)
  – Lack enterprise perspective (horizontal integration)
• Point-to-point data exchanges using military
  message formats
  – Difficult to implement
  – Expensive to maintain
• Current systems must co-exist with new
  web-enabled systems
  – Same data is needed to support processes

           Describes AS-IS Data Exchange
• Translates IERs into a form useful to Data Modelers
   – Implemented in OWL, a W3C ontology language
       • Supports re-use: No need to re-engineer for each DM
       • Generates code: could be used as core for future Physical Data Models
   – Uses C2IEDM v6.1 for core concepts
       • C2 data used supporting multi-national operations
       • System-specific concepts flagged as potential extensions to C2IEDM
• Supports IER refinement
   – Early identification of gaps
       • E.g., new data requirements introduced by system implementations
   – Eliminate need for rarely used data concepts.
• Supports Net-Centric Data Strategy
   – Reduces need for pair-wise system-specific interfaces
   – Supports management of Net-Centric Checklists

       C4ISR Data Ontology
   Applies to Net-Centric Attributes
ASD/NII Net Centric Checklist questions are
designed to gather program information to assist
DoD leadership in better understanding our
move to net-centricity.
Questions are tagged as Foundational [F] or
Discovery [D].
 – Foundational questions relate to a net-centric attribute
 – Discovery questions relate to how programs implement a
                 The DoD C4ISR Data Ontology

                    C4ISR Data Ontology

•   Translate IERs into a form useful to Data Modelers
     – Supports Re-use: No need to re-engineer for each COI’s DM
     – Generates code that can be used as core for Physical Data Model (SV-11)
•   Flexible, Conceptual Representation
     – Allows system-specific dialects
     – Keeps system-specific concepts hidden from other systems
•   Supports Net-Centric Data Strategy
     – Configuration managed organizationally aligned with Army COIs.
     – Configuration Management scales to DoD {and broader) enterprise scope.
•   Reduces Complexity
     – Reduces need for pair-wise system-specific (and COI-specific) interfaces
     – Objective identification of potential extensions to C2IEDM (and other core DMs)
     – Early identification of gaps
         • E.g., new data requirements introduced by system implementations
     – Supports IER refinement: Eliminate need for rarely used data concepts.

    Communities of Interest (COIs)

                                  in pursuit of their shared

COI define shared vocabulary, information to be shared, how it
should be shared.

    DoD Net-Centric Data Strategy is now Policy (DoD 8320.2 & AR 25-1)
•   All must identify, prioritize, select information (data assets) to be shared with the
    enterprise, and designate authoritative data sources
•   Mission Areas and Domain leads must organize for battle by…
     – Forming and resourcing expedient COIs (lead/support joint & Army)
     – Forming Army Institutional COIs (focus area)
•   CIO-G6 is organized to support Data Strategy implementation of Mission Area &
    Domain leads with:
     – Services and Methodology (COI Administration, Data System Engineering, Data
        Modeling and products, Configuration Control, & Data Test Support)
     – Best Practices/Lessons Learned (COI Program Management Plan)
     – Policy & Guidance (Draft COI Policy, Draft COI Guidance Document, initial draft
        of Data Engineering Guidance Document, & DA PAM 25 1-1)
•   CIO-G6 teamed with Navy & Air Force to ensure common approach to implement
    Net-Centricity through Net-Centric Enterprise Support for Interoperability (NESI)
•   System Engineering and Integrated Architecture approach is required to execute
    Data Strategy. (CJCSI 3170 - JCIDS process)

Data Strategy is critical but not sufficient to achieve Net-Centricity
