If you read my messages again, I was only trying to say
that SAM API (not necessarily the SAM in the form that it exists now, but
SAM 4.7, or whatever)
is the most convenient one for TAO Topic Maps (sorry, Martin, it is just
very convenient to say this way).
Also note that SAM tools are by definition RM tools - so I do not understand

Oops, I am not an RM person. I am an RM&SAM person.

Excellent! Surprisingly I have also done this for leaving (and I liked it).

Are you talking to me? :-)
Where in my messages did you find these claims?
I think that "simplifies" is a wrong word. See bellow.

I think that the confusion comes from the notions of SAM and RM.
When I am using them, I am referring to the future versions of SAM & RM,
they may even have different names then.
I agree that SAM may be THE API for XTM, HyTM and any structures directly
mappable into XTM.
(I actually liked Michel's "TAO model" naming suggestion.)
But lets try to embrace other knowledge structures.
You, Lars, said that you had mapped arbitrary structures into XTM (or SAM)
and it was easy..., -
what exactly have you done? What had driven you to map those structures to
one topic map construct or another?
I think that you had implicitly (without admitting that - almost
unconsciously) parsed those constructs to the RM level and then reassembled
them on the TAO level, decided on the ontology, etc.
All I am saying is: lets make hidden explicit.
It is not diminishing the value of the SAM.
But it expands the Topic Maps territory.
I would say "we are saying" here if I were absolutely sure that Michel,
Patrick and others share this view.
I think that our vision is very close.
