RE: [xtm-wg] Knowledge management claims re XTM (and Topic Maps.. .)

[Peter Jones <peterj@wrox.com>]

Hi,

I posted on the matter of (a) a while back (text inserted below), and
wholeheartedly agree with (b).


<from the earlier posting: Grandfathered public topics [was: lazy
processing...]>

>but we need some real basic stuff like simple logical expressions.

Following some postings to the list, I had (a revelation) and an off-list
discussion with Steve N and Michel about this. Topic Maps (ISO 13250)
deliberately omit any logical stuff (e.g. operators and quantifiers,
disjunction types, term equivalence and substitution rules, etc.) from the
specification. This is because a Topic Map can (if you want) present a set
of denotations needed for the terms of a set of logical expressions in
whatever format/syntax those are expressed. That way it provides a resource
to existing syntaxes for logical expressions like Knowledge Interchange
Format without reinventing the wheel. Clever, eh? 
(I nearly fried my brain when I spotted that one.)

cheers
Peter

Hi folks...

I don't know if you discussed this at all in Montreal, but I am very
concerned that XTM should encourage/facilitate good working-with t
long-standing academic knowledge-engineering community by 
a) being (very) moderate and realistic in its claims for XTM *by itself* as
a knowledge modelling technique - XTM's main strength could well be in
providing the "hooks" which enable the wide range of established knowledge
modelling techniques to link to Web resources, and also in providing simple
exchangeable *static* representations of (some) such models;
b) working with folks who have done eg semantic modelling for years, rather
than trying to (re)invent ways of doing it without the benefit of that
experience.

This concern is based on back-of-room conversations at XML Europe, where I
found myself trying to bring some experienced knowledge engineers "back down
off the ceiling", and into a more realistically appreciative frame of mind
regarding Topic Maps, after some rash claims from the podium...

Cheers

Ann W.
