[topicmapmail] DRAFT: Datatypes for XML Topic Maps

[Kal Ahmed]

Murray,

This is interesting work. There are a number of things which I would like=
 to=20
hear your thoughts on.

Firstly, have you looked at any of the proposals for structuring scope [1=
]=20
[2]. I think that a structured scope is needed for your proposed datatypi=
ng=20
mechanism to work.=20

Secondly, have you given any thought to ways in which derived simple data=
types=20
and complex could be built from the datatypes you have presented here.=20
Intuition tells me that a "derivation" and "restriction" association type=
=20
could assist in creating derived simple types, and that reification would=
=20
play a role in building complex datatypes...

Cheers,

Kal
