Project Focus
• Based on white paper describing DoDAF, SysML
and AP233 standards for System-of-systems and
Systems Engineering
– Using Systems Engineering Standards In an
Architecture Framework by Ian Bailey, Eurostep, Fatma
Dandashi and Huei-Wan Ang, Mitre Corp, and Dwayne
Hardy, American Systems Corp
• Influenced by INCOSE, ISO STEP and OMG
communities

Standards and SE data
• DoDAF - DoD Architecture Framework
– Defines standardized views of systems information
– CADM = Core Architecture Data Model
• International Council on Systems Engineering (INCOSE)
and Model-Driven System Design
– Model-Driven SE Semantic Dictionary and Concept Model
– Group work results in SysML/AP233 and alignment activity
• SysML - from Object Management Group
– Provide a standard modelling language and notation for systems
engineers
• AP233 Systems Engineering - ISO 10303-233
– Defines a neutral information model for complex systems
engineering structures

Project Technical Summary
• Scope
– SV-1, SV-2, SV-3, SV-4, OV-5, TV-1 subset
• Purpose
– Evaluate feasibility of system architecture data exchange using
emerging ISO AP233 Systems Engineering standard
• Not a fully validated design effort
– Provide a body of work that future efforts can build upon
• Deliverables
– Primary deliverable is documented mapping between DoDAF CADM
XML format and the ISO AP233 XML format
• Delivered as a Web site
• Audience is software developers writing CADM-AP233 translators
– Software that coverts between CADM XML and AP233 XML

Resulting Tool Interoperability
• CADM-AP233 interoperability creates a new path
into DoDAF for:
– UML/SysML tool vendors
– Non-UML tool vendors
– Other military AFs
• UK MoDAF Enterprise Reference Model
• CADM-AP233 interoperability creates a capability
to feed DoDAF data down the systems life cycle
via other STEP APs
– e.g. AP239/Product Life Cycle Support for Support
Engineering, Maintenance, Logistics, etc.

Conclusions
• Core DoDAF Views/CADM and AP233 can be mapped
– Provides additional path for creating CADM data for tool vendors
– Only 6 of 20+ views included in the current activity
• Confirmed white paper conclusions on SysML, AP233 and
DoDAF each being useful
• Deliverables approached so it is possible for them to be
reused as the basis for future work
– CADM-AP233 mapping documented as a Web site
• AP233 portion could be reused in SysML-AP233 mapping
– Prototype implementation of CADM<->AP233 plus some extra
tool-specific software for demonstration purposes
