Agenda
• Background
• Motivation
• DDML and Translator Review
• DDML Status
• DDML Translator Status
2003 Knowledge Based Systems, Inc.
Background • Work based on a Phase I and II SBIR sponsored by
Edwards Air Force Base• Technical POC: Dr. Charles Jones• Work with
– China Lake / Lockheed Martin, Ridgecrest– NAWS, Pt. Mugu– Pax River Test Range Center– PM Utility Helicopter, U.S. Army– Sherrill-Lubinski Corp– Symvionics Corp.– Bruce Lipe, EAFB– Jon Morgan, EAFB
• Project ends Nov 2006

Why Neutral Language?
• Data display setup is a lengthy procedure• Diverse data display systems• Test and Evaluation (T&E) performed at
different locations• Need reuse of displays for joint service
T&E missions– Joint Strike Fighter (JSF)– Joint Air-to-Surface Standoff Missile (JASSM)
2003 Knowledge Based Systems, Inc.
Why Neutral Language? • Currently, displays are created manually
• Develop translators without neutral language

Data Display Markup Language• Based on eXtensible Markup Language (XML)• Four logical layers: graphics resources, dynamics,
variables and data sources• Includes most T&E display objects
– plotters, meters, strip charts, etc.
• Primitive graphics resources based on Scalable Vector Graphics (SVG)– rectangles, lines, etc.
• Generic to support nonstandard objects
2003 Knowledge Based Systems, Inc.
Data Display Markup Language• Layers similar to typical software architecture
Typical Software Layer(e.g., Model-View Architecture)
Persistence(load, save, etc.)
Information Management(objects, variables, etc.)
Graphics Resources(controls, color, etc.)
User Interfaces(rendering, display, etc.)
DDML Layers
Data Sources
Data variables and derived data
Graphics Resources(position, color, etc.)
Dynamics

DDML Design
• DDML is generic enough to support multiple data display systems, despite– Nomenclature differences across tools– Different functionality and focus for each system– Architectural differences and fuzzy specification
of architectural layers– Nonstandard, tool-specific concepts
2003 Knowledge Based Systems, Inc.
DDML Design artifacts
• Data dictionary – Excel-based– Maps vendor objects to DDML elements and
attributes
• IDEF1X data model
• Special mapping rules file
• XML Schema
• UML Model (in progress)
2003 Knowledge Based Systems, Inc.
DDML Details• <model> contains all display objects on a given
screen.• Standard display objects including
– <stripchart> – <barchart>– <piechart>– <dial>– <slider>
• Non-Standard/Custom objects– <object>
2003 Knowledge Based Systems, Inc.
Data Display Translator Framework• DDML Model Repository with Translators
2003 Knowledge Based Systems, Inc.
DDML Benefits• Supports interoperability of display systems
– Same look and feel across environments and test centers
• Vendor-independent way of cataloging display information
• Can be used in various environments– T&E missions– Industrial process control– Cockpit and automobile dashboards – Health monitoring: man and machine

DDML Status
• DDML Version 2.0 presented at 112th RCC Telemetry Group Conference
• Several Suggestions made by Attendees– Convert XML Attributes to Elements– Use MathML for derived variables– Develop UML model for further
documentation.
2003 Knowledge Based Systems, Inc.
DDML Status
• Current DDML Version: 3.0
• Changes since 2.0– All XML attributes have been converted to
elements, except for id.– DDML <expr> element replaced with MathML
<apply> element.– Improved <rules> logic for defining thresholds,
etc.

Attributes to ElementsDDML 2.0
<barchart id="BAGC1“ name="BAGC1“ scrollDirection="down" title="Title" titleColor="0“ valueAxisMin="0“ valueAxisMax="5“ valueAxisLabelForegroundColor="0“ valueGrid1Color="16711935“ valueGrid1Quantity=“2” valueTicLabelForegroundColor="0“ valueTicLabelFormat="%4.2f“ valueGrid2Color=“58302”
DDML 3.0
<barchart id="BAGC1"> <name>BAGC1</name> <scrollDirection>down</scrollDirection> <title>Title</title> <titleColor>0</titleColor> <yAxis> <axisType>value</axisType> <axisMin>0</axisMin> <axisMax>5</axisMax> <axisLabelForegroundColor>0</axisLabelForegroundColor> <axisGrid> <axisGridColor>16711935</axisGridColor> <axisGridInterval>2.5</axisGridInterval> <tickLabelForegroundColor>0</tickLabelForegroundColor> <tickLabelFormat>%4.2f</tickLabelFormat> </axisGrid> <axisGrid> <axisGridColor>58302</axisGridColor> </axisGrid> </yAxis>

Example: 3x2 – sin(y)
MathML for Derived Data
DDML 2.0
<exp>
<exp coef="3" power="2" var_ref="x" />
<exp coef="-1" power="1" oper="SIN" var_ref="y" />
</exp>
DDML 3.0
<apply> <minus /> <apply> <times /> <cn>3</cn> <apply> <power /> <ci>x</ci> <cn>2</cn> </apply> </apply> <apply> <sin /> <ci>y</ci> </apply></apply>

Improved Rules
DDML 2.0
<rule> <if start="0" finish="0" /> <then value="16711680“ /> <else> <rule> <if start="1" finish="1" /> <then value="65280“ /> </rule> </else></rule>
Example:if (var == 0) value=16711680else if(var == 1) value=65280
DDML 3.0
<rule> <if> <operator>EQ</operator> <value>0</value> </if> <then> <value>16711680</value> </then> <else> <rule> <if> <operator>EQ</operator> <value>1</value> </if> <then> <value>65280</value> </then> </rule> </else></rule>

DDML Documentation Status
• DDML 3.0 Improvements documented– ITC 2006 Paper
– ITEA Test Instrumentation Workshop 2006 Paper
– Both of these are intended to gain feedback from T&E community.
• DDML website maintenance– http://www.kbsi.com/DDML/DDML.htm
• 3.0 Schema and UML model will be on website soon.

DDML Translator Status
• DDML translators in use by Pt. Mugu to support transition from GRIDS to RangeView.
• Progress on SL-GMS translator
• Maintenance of DataViews, IADS, and C++/OpenGL translators.
2003 Knowledge Based Systems, Inc.
Conclusions• DDML is a generic XML-based neutral
language for data display applications• DDML has been tested to support at least
three vendor-specific formats• DDTF provides integrated framework for
future translators• DDML and DDTF have applications
beyond T&E
