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

All your True/False propositions are clear false. As Jim Melton said, they have all been done for decades with relational databases, for one thing. You could think of telemetry data as an example, where streams of data are interleaved, and extended over time, linked in this case primarily by time codes.

Furthermore, RDF in principle can be considered as a kind of highly normalized relational database, with one two-column table for each kind of relation (i.e., property type). So even if your claims about the need for RDF were sound (which they are not), you could still rightly consider a relational model.

The key to modeling this kind of data is finding out what entities in the different chunks correspond to each other. Once you have that figured out, you can model the thing in any number of ways.

Hi Folks,

So, you have lots of chunks of data and the chunks are highly
interrelated. Over time more chunks are added and those new chunks
are easily connected in with the other chunks, i.e., the system
expands over time.

Example of highly interrelated chunks of data: You have data about an
aircraft in flight: its current location, speed, heading, etc. You
have data about the aircraft itself: fuel capacity, max speed, max
altitude, cruising speed, date built, model number, etc. You have
data from FAA radars tracking the aircraft. 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.

[True or False] The only reasonable way to express an expandable
system with lots of chunks of highly interrelated data is with RDF,
RDF Schema, and/or OWL. It is not practical to express an expandable
system with lots of chunks of highly interrelated data using vanilla
XML.

[True or False] When dealing with an expandable system with lots of
chunks of highly interrelated data it's not practical to use XML
Schema to validate the data.

[True or False] When dealing with an expandable system with lots of
chunks of highly interrelated data you must adopt the Semantic Web
technologies such as inference engines, triple stores, SPARQL,
knowledge bases. And your trading partners will naturally join you in
your adoption of the Semantic Web technologies.

[True or False] Nobody has ever implemented an expandable system with
lots of chunks of highly interrelated data using vanilla XML and
using XML Schema for validation. Or, if they did, it was a complete
failure.
