Who am I?

• David Price– ~20 years at IBM as Senior Software Engineer

• Mechanical CAD support, Corporate Design Practices• IBM Consulting, IBM Enterprise Integration• Assignee to PDES, Inc. consortium developing ISO STEP

stds

– ~4 years at Eurostep Limited as Senior Consultant• Oil and Gas data warehouse standards/implementation• Ship Classification data exchange UML/XML Schema

project• ISO AP239/PLCS Semantic Approach to Taxonomies for

data exchange for UK MoD• Open-source Web site www.exff.org dedicated to data

exchange and modeling language interoperability

®


What is Eurostep?

• Eurostep Limited– Consulting company based in UK, part of Eurostep Group

operating in UK, Sweden, Finland and USA• Eurostep Sweden commercial product Web-enabled PLM system

– Typical Customers : BAE SYSTEMS, UK MoD, Volvo, NASA/JPL, Boeing, FMV, AstraZeneca, John Deere

– Decades of experience in ISO STEP and OMG standards– Decades of industrial experience in Aerospace, Ship

Classification, Logistics Support, PLM, Mechanical Engineering, …

– Related projects• SEDRES 2• PLCS Consortium Project and Technical Coordination• ISO STEP AP239/PLCS and AP233/SysEng modeling• SysML submission team member

®


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
