1. A Federated Architecture Framework Roadmap
UNCLASSIFIED

2. Common Problems
NIEM, UCORE, XSD, MOF, UML & UPDM suffer from a common set of problems that inhibit information sharing of architectures and therefor of information in general
Dependence on structural reuse of static data structures
Instead of logical information and semantic reuse
Closed information structures
Instead of open, web-oriented federation
Fragmented “cores” and domain vocabularies
Instead of loosely coupled libraries of reusable concepts
Lack of a consistent and robust architectural framework for defining architecture
We have to stop trying to define logical models based on technology representations (like XSD or even RDFS) – put the logical model “on top”.
UNCLASSIFIED

3. UCORE & NIEM Both define a XML/XSD centric data model
Both define “cores” using their respective XML/XSD model
Both need a cleaner logical information structure not dependent on XSD
UCORE is more general, cleaner and narrower in scope
NIEM is huge and needs to be refactored
Potential Solution
Define a DoDAF compatible logical information model profile that will work for both UCORE and NIEM
Refactor the “cores” together, use UCORE as the “upper ontology” for NIEM
Use MDA to separate logical information from technical representations

6. Information Sharing Architecture Framework Sources
Logical Information Profile
Derivative of NIEM-UML and UCORE Implied Logical Model
Makes the logical (DoDAF) representation the primary representation and various technology forms (like XSD or RDF) derivatives via MDA.
Upper Concepts
Derivative of UCORE model, perhaps other upper ontologies
Influenced as required by NIEM-Core
Common Concepts
Mostly a refactoring of NIEM Core & Reference namespaces
Influenced as required by DoD communities
Domain Concepts
Defined by communities of interest – provided for but out of scope
Secure Information Model Profile
Derivative of UCORE, SoaML, IEF/IEPV & Global Reference Architecture (Justice Community)
Technology Mappings
Defined as required for technical profiles – may or may not be unified across NIEM & UCORE

DoDAF Concepts
Build DoDAF out of the “same stuff” as other information sharing capabilities!
UNCLASSIFIED

8. What About IDEAS? Provides many good concepts, but Suggestion:
Is not rooted in any accepted standard
Tiny community
Conceptually difficult to understand
Due to combination of existential and 4D semantics
Suggestion:
Use IDEAS work as input into a next generation architectural framework
Include as input semantic web and other semantic approaches
Define DoDAF in terms of these standards
UNCLASSIFIED

9. Timeline (OMG Processes)
2012
2013
2014
Logical Information Model Profile
Common Cores
Secure Information Services Profile
Federated Architecture Framework
Notes:
Logical Information Model Profile & Common Cores are done together as they are mutually validating.
Services profile has minimal coupling to the above.
Federated architecture framework can start once the above pieces are starting to solidify.
UNCLASSIFIED

10. Supportive Processes IEF/IEPV for privacy and security Mof2RDF
Provides foundational model for privacy and security
Has multiple RFPs, starting to deliver mid 2012
Mof2RDF
Provides for mapping any MOF (UML) model to RDF
Can assist in improving the federated web architecture for UPDM – query across distributed architectures
However, this is a structural mapping – it does not impact semantics
Expected late 2012
Semantic Information Modeling for Federation
Provides for conceptual and logical modeling of information
Bridges between different conceptual, logical and physical models
Provides for semantic interoperability
Expected late 2013
