What’s the Challenge…
C4I spans a much larger set of systems…
• Not in the same domain
• Not managed/funded by the same PM
• Leverage different TRFs
• Different timelines for integration
and technology refresh cycles
What’s the Challenge…
What makes this hard?
•
•
•
•
There isn’t a common interface specification…
Different temporal constraints and requirements…
We can’t standardize on one protocol…
Configuration & implementations vary…
It that is? Something else, at the root?
• It’s the data’s content, context & behavior
• It’s an integration scalability problem
What’s been done…
• Where else has content, context
and behavior been thoroughly
defined?
• Compilers!
• Syntax – content
• Semantics – context
• Operations – behavior
• Consider what’s been done with
these rigorous definitions…

What’s been done…
• What made this transform possible?
• Machine readable, rigorous, and closed
input, output, and rules specifications
• Something like Extended Backus–Naur Form
• Define “Rigorous”?
• Solid mathematical basis & foundations.
• Not just machine readable
• Must be machine understandable

Current progress… An Example
• Two message definitions – talking about the same thing, or not?
enum AlarmLevel {
GREEN,
RED,
YELLOW,
NO_STATUS,
NORMAL
};
struct alertType : Header {
float x, y, z;
double set_angle;
AlarmLevel status;
};
??
public final class VehicleStatus implements java.io.Serializable
{
public String ID = null;
public Position3D_WGS84 location = null;
public EngineSpeed_RadiansPerSec speed = null;
public VehicleStatus (String _id, ... )
{
....
}
}
Current progress… An Example
• Two message definitions – talking about the same thing, or not?
• Demonstrations have shown this to work!
• Still more to do, but really exciting.
• Interesting with small number of messages, powerful with 1000’s
• ICD Verification & Data Rights
• Own the rights things with the right level of detail
Where are we going…
• Pragmatic and Dynamic Interoperability Concerns…
• The ‘data of behavior’ which informs the transformation
• Have – Service descriptions and human understandable forms
• Needed – the machine understandable equivalents.
• Its hard, is takes time and there is no
magic transform
• Take a page from history, it can be done
• Have to be rigorous in the rules
• We can’t stop current progress
