Re: [xml-dev] Dealing with lots of chunks of highly interrelateddata?

Capture is one thing.  Interchange of information between dissimilar 
systems is another.

Moreover, there are no simple rules for deciding which kind of tool or 
representation is best for a given situation.  Here I'm including 
"moment in history" in the general definition of "situation", where 
"situation" also includes, but is not limited to, all the issues that 
arise from the distinctions that may need to be made between 
interchange, capture, and processing-for-some-purpose.

So, in the general case, these true-or-false questions are all vexed.  
There's another pair of problems, too:

    * Is there some reason to limit all relationship-modeling to RDF?  
More generally, is there *any* relationship-model that doesn't fail somehow?

    * Is there some reason to limit all interchange representation to 
XML?  More generally, is there *any* interchange representation that 
doesn't fail somehow?

For good or ill, choices must be made, regardless of the complexity of 
the issues involved in making them.  There's no substitute for real 
engineering.

You have data about the destination and originating points of the aircraft. You have data about the passengers on the aircraft. And you have many other chunks of relevant data. And, the relationships between all these chunks of data must be captured.
