Three Areas
• (Area 1) Expand TOGAF to include Real-time and Embedded concepts
• (Area 2) Integrate TOGAF with a much more prescriptive process such as RUP (Rational Unified Process) or openUp, for a complete Enterprise to working code approach to Real-time and Embedded projects
• (Area 3) Identify techniques and specifications that could be incorporated into the process to support Real-time and Embedded needs

(Area 1) Model TOGAF
Model TOGAF in SPEM2 and use SPEM2’s generic ability to extend/replace the description as a way to let The Open Group’s various working groups publish their extensions independent of TOGAF.
Also the use of SBVR looks promising to remove some of the ambiguity of statements in the standard.
![Page 9: Real-Time and Embedded Forum and TOGAF (19 Oct 2009) G. Edward Roberts Elparazim eroberts@elparazim.com.](https://reader035.fdocuments.us/reader035/viewer/2022062423/56649e3f5503460f94b3096d/html5/thumbnails/9.jpg)
Discussion of Area 1• Discussion of Wednesday Morning meeting at The
Open Group’s Toronto Meeting• Microkernel Kind of Architecture• This was not just a RTESF problem• Many groups wanted to extend TOGAF• Example: Why do we have a SOA chapter in
TOGAF itself?• Need a “add-in” concept that is formal, and can
be “mechanically combined”

SysA Metamodels of Interest
• SAEM (Software Assurance Evidence Metamodel)
• ARM (Argumentational Metamodel)
These two meta-models could allow descriptions to be made of what would constitute Assuredness/dependiblity in a real-time system

Next Steps• “drink our own champagne”, Architect TOGAF
(perhaps with a modification of our own methods)[some work done here]
• Model TOGAF 9 in SPEM2, using Micro-Kernel concepts
• See if SBVR could be used to make statements unambiguous
• Study SAEM and ARM metamodels (description of certification)
• Do some prototyping
![Page 26: Real-Time and Embedded Forum and TOGAF (19 Oct 2009) G. Edward Roberts Elparazim eroberts@elparazim.com.](https://reader035.fdocuments.us/reader035/viewer/2022062423/56649e3f5503460f94b3096d/html5/thumbnails/26.jpg)
TasksTask 1: Adjust TOGAF for extension (Model TOGAF – SPEM2, SBVR)
Task 2: Go Through TOGAF and Note RTESF Differences/Additions
Task 3: Work out how one Certifies RTES (includes SAEM and ARM)
In Parallel
Task 4: Work out how Technical Architecture Process
Task 5: Work out how Technical Architecture Methodology (SysML, AADL,UML)

ExecuteWithin is a stereotype that is created by a para-functional designer in a UML2 Profile. It indicates that the Operation it marks should execute within the given nanoseconds.

The Tester can immediately see in the tool where the constraint violations happened and in which code.
