Dear Daniel,
yes, I said that the grey zone is a relic of the past,
It is there and we have to deal with it.
But that is not to say that it must stay the same.
To my mind we have to be aware that when dealing with semantics and IT
we must stay close to the eons proven way to do things.
For eons we have had as semantic ingredients:
- a list of words (nouns and verbs) plus modifiers (adverbs,
adjectives): dictionary/vocabulary
- a syntaxis/grammar
- ways to define what makes sense.
The list of words/dictionary/vocabulary defined the concepts building
block to be used in grammar.
Using words and grammar we could produce sentences and express what we
had to express.
But we could produce sensical and non-sensical combinations of words
and grammar in sentences.
Therefor we had ways to select and use only the sensical sentences.
And these are archetypes and templates.
Archetypes and templates -in addition- provide the patterns (types of
sentences) that can be used in healthcare to document observations,
evaluations, instructions, and actions.
We must think very carefully whether it is wise to have two grammars
at the same time.
Archetypes and templates have on one hand the role of grammar and the
pattern used for documenting.
What is a compelling reason to combine the role of a code-list with
that of grammar in SNOMED?
Does SNOMED have a rich enough grammar?
As rich as archetypes and templates allow?
Does it has a way to deal with patterns?
Isn't it a solution for the grey zone problem to accept that from now
on we use SNOMED as a code list / vocabulary, that eventually helps us
reasoning because of the ontological features?
And that archetypes and templates are the grammar and the expression
patterns?
Coding systems are a fact of life.
Archetypes and templates are a fact of life.
Both need a natural role.
Isn't this suggestion the most practical way to deal with the grey
zone in the future?

I didn't say that the grey zone is a relic of the past but, quite
differently, a fact we need to acknowledge and relate to. The main
reason: terminologies are not just merely dictionaries but make
assumptions of semantics that interact with assumptions of semantics
made in archetypes. Also, in terminological languages, representations
of the semantics may be processed formally.
