John,    (01)

The comments I quickly made was related to the lack of rigor and 
critical reviews in general. The patented CCTS uses both a signifier 
(dictionary entry name) and a definition is specified. The short 
definition observation I offered was regarding the definition practices. 
In many cases the content of the definitions seems redundant. I tried to 
leave the most interesting discussion re definition vs axions for later.    (02)

A designation expression for a binary relation concept follows a grammar 
("ClassTerm"+". "+"roleTerm"+". " + "relatedConceptTerm") and the 
prevalent practice of a specifying oneline definitions follows simple 
english patterns. Just taking the words in a designation and rearranging 
them seems as a *weak* practice that adds little additional explanatory 
effect (in addition to the already available designation).    (03)

Designation: "Accounting Entry. Value Date. Date Time"
Definition:  "The date, time, date time, or other date time value of the
value date of this accounting entry."    (04)

I made a small application some time ago that traversed the definitions 
and tried to calculate how much text of the definitions were based on 
words patterns based on designation words. Over 60% of the definition 
text seemed to following word patterns.    (05)

Unfortunately the CCTS does not ,in practice, offer many alternative 
mechanisms for representing axioms.In additions to concepts, 
hierarchically oriented binary relations ('basic property' and 
'association property') and a 'based on' sub-component derivation 
mechanism there are few other options to use for axiom specifications. 
The so called "Usage rules" are not used at all, except for "data types"    (06)

So true, An interesting comparison would be to try to assess whether 
newly developed CCTS libraries and its new XML syntax solution provides 
a significantly "better" foundation for interoperability than EDIFACT. I 
just talked to a major global industry organisation and they said that 
EDIFACT solutions are still in very high demand.    (08)
