I certainly agree! Later may in fact turn out to be too late, so the
sooner this is decided the better.

| is the wrong thing, would be to go to the www.topicmaps.org, download
| the AG Review Draft, study it, and give feedback on it.

My concerns with the graph formalism are mainly these:

 - it is far removed from the actual form of implementations, making
   it much harder to understand for implementors, which are after all
   the intended audience

 - it is insufficiently detailed in that some properties of the nodes
   in the graph are left out, even properties of great importance to
   processing 

 - the form the graph is specified in (property-less nodes connected
   by arcs with endpoints of two types) causes the description to
   become difficult to follow, since everything is so type-less and so
   very similar everywhere

However, I think complaining about these things is far less effective
than showing what I mean by actually presenting an alternative that
uses the kind of formalism I would prefer. I think that would make it
far easier for people to decide what they think is the better
formalism.

I will present a sketch of such a processing model in my next posting.

I think you have done what you possibly can for now.

| of tact.

This vendor is not Ontopia. It may be some other vendor, but if so I
know nothing whatever of it.
