You can patent reinventing Prolog?? Or is the pending patent
on connecting a TCP/IP library to a reinvented Prolog engine?
Or a perhaps method and apparatus for maintaining and querying
a tuple-pile, either locally or located on a different piece
of apparatus connected by a shared communications apparatus?

It gives the impression you're trying to make your TDM model look better
than others by omission, rather than giving a clear comparison.

How is it different from Mainstay's Phyla, eg: as reviewed at
<http://www.tidbits.com/tb-issues/TidBITS-160.html> apart from the
obvious aspect of being available as a callable DLL?

The GUI and ability to navigate down through a connected, possibly
cyclic graph, just by opening successive levels in a tree are certainly
similar.

I'm not saying you copied anything but (as I've often found!) other
people have bright ideas too, hence the (now neglected?) test of
"obviousness" in patent examination.

If you could provide a commonly accepted term and a fairly precise
definition that describes the relationship between objects, the web
page can be updated.

For example, since chapter VI of "An Intro to Symbolic Logic" by
Langer discusses "relation" at length, it was included in the chart
comparing terminologies. While Microsoft's VB Programmer's Guide is
not be an authorative ref, in chapter 7, Intro to Objects, the closest
it came was a section titled "How are Objects Related to Each Other?"
but the precise def was vague and mostly by examples in two short
paragraphs. If you could site an authorative OO reference, it would be
helpful.

An interesting db, and the Mac and it's OS are amazing. I have no
prior experience with Phyla. Phyla seems to provide a much
higher-level of abstraction, although the example relating Users,
Software and PCs could also be implemented in XDb, except
relationships between things are not named (ie "Is Used By", "Is
Installed On", etc) but derived, if possible.
