Introduction to DODAF, MODAF and UAF
The most common system reference
architectures in the military field are：
- DODAF is the architecture reference
framework for the United States Department of Defense
- MODAF is the architecture reference
framework for the United Kingdom Ministry of Defence
- NAF is NATO's architectural
frame of reference
- UAF unifies the architectural
frameworks of DODAF, MODAF, and NAF
DODAF is the earliest military
domain reference framework and the reference foundation
for other architectural frameworks, DODAF provides
eight perspectives on architecture, as follows：
OMG provides the Architecture
Modeling Specification UPDM for DODAF based on UML
and Sys ML, providing a common modeling language for
architecture modeling.
UAF has also established a corresponding
UAF modeling language on the basis of UPDM.
2.Introduction to the Modeling
Tool EA
The modeling tool EA is currently
the most popular tool, which has been widely used
in the fields of automotive electronics, aerospace,
shipbuilding, rail transit, enterprise informatization,
system engineering, and software engineering, and
has accumulated a large number of users and cases.
The modeling tool EA also provides
modeling support for DODAF and MODAF, including support
for the corresponding modeling language UPDM, and
provides corresponding modeling wizards and model

6. Introduction to the Architecture
Engineering (DODAF, MODAF, UAF) toolchain
In order to effectively support
the architecture engineering of DODAF, MODAF and UAF,
it is necessary to establish a complete set of engineering
environment around the model, so that the model can
support specific work and realize the continuous accumulation
and development of the architecture. To this end,
we offer a complete DODAF, MODAF and UAF toolchain,
with a brief table of contents as follows:
| DODAF Work Scenario |
Supported tools: |
| 1. Establish a DODAF
process guide |
iSpace |
| 2. Build a DODAF model |
EA or iSpace |
| 3. Modeling Wizard:

| 4. Automatic Modeler |

| 5. Generate DODAF architecture
documentation |
DocGenerator |
| 6. Architecture Quality
Review |
iNspector |
| 7. Simulate the system |
Simulator |
| 8. Build a model library
and establish a continuous accumulation mechanism |
ModelCenter |
| 9. Publish the model,
use the model, and review the model |
WebEA |
Here's a brief overview of the
system simulations, process guides, and model libraries
that are part of it.
6.1 Model simulation of multi-system
cooperation
After establishing the architecture
based on DODAF, the system needs to be simulated and
verified, and the multi-system simulator provides
system-level simulation capabilities, which can simulate
the cooperation of multiple systems to complete operations
and realize capabilities. Based on simulation, the
correctness and completeness of the architecture can
be verified.
6.2 Modeling Guide: iSpace
DODA F, MODAF, UAF modeling is
a complex and long-term process, so the current specification
also regards the architecture development process
as part of MBSE, and it is necessary to provide corresponding
process guidance models, and track and manage processes,
deliverables, and roles. The MBSE platform iSpace
provides the following process support for DODAF and
UAF:
• Guidance on the architecture
design process
• Relevant roles and
responsibilities
• Various models, documents,
and tracking relationships delivered
The following is a screenshot
of the process guide interface of iSpace's DODAF:
Here's a screenshot of the
artifact model for iSpace's DODAF:
6.3 Model Library: ModelCenter
Complex architecture engineering
is not something that can be successfully achieved
by a few people in a short period of time, but requires
team cooperation and long-term accumulation, and the
continuous construction of corresponding specifications,
which requires a model library that can support complex
architecture. To this end, we provide a library of
multidimensional models that can be stored and provide
convenient online management.
DODAF, MODAF, UAF models can be
established in the multi-dimensional engineering model
library, and the association of multiple models can
be realized. Managers can review the model and then
publish it, using the architecture model as a resource
for business analysis, system construction, and personnel
development. This is the key to realizing the value
of DODAF, MODAF, UAF models.
6.4 Model Publishing: WebEA
Models can be published through
WebEA, so that everyone can browse the model, use
the model, and provide feedback mechanism to the model
through the web page, so that the model can become
a reference and basis for daily work.

About the Author:
Zu
Tao, the founder of Dragon Fruit Software Engineering,
founded Dragon Fruit Software Engineering in
2001 and the IBM Rational User Group in 2004.
In 1998, he participated in the national key
research project "Component-based Software
Reuse for Specific Domains" as a backbone,
and was fortunate to learn and use UML for domain
modeling and refine reusable components and
architectures. In the subsequent R&D projects,
the model has been used for analysis and design,
and has accumulated some experience and experience.
Over the past 20 years, I have been focusing
on MBSE, familiar with UML, Sys ML, ArchiMate,
BPMN, UPDM, DataModel and other modeling languages
and specifications, in the past experience,
the biggest feeling is that the field of software
engineering and systems engineering, which has
brought together many elite talents, has been
a messy and confused state for decades. And
from their own engineering practice to extract
experience, the formation of their own sustainable
methodology, such as "Natural Language-based
Modeling Language NML", "MBSE from
Method to Practice Guide", "Model-based
3D R&D Management", "Model-based
Requirements Management", "Model-Driven
Architecture Design", "Model-based
Quality Management", "Model-based
Personnel Capability Management", "iProcess
Process Improvement Method", and is currently
working on MBSE as a product manager and architect
The research and development of the (model-based
systems engineering) platform hopes to establish
model-based engineering solutions, and will
continue to write some articles in the future,
hoping to give some reference to peers.
