Hello Alan,

Once again you have authored a very promising document.
While reading it I wrote down a few comments, mainly details, see below.

Best,

Fabien


[Section: Transitive relations - parts and direct parts]
"(...) will draw the conclusions that the parts of C include both A and B."
I understand what is meant here but (probably because I am not a native 
speaker) I find it ambiguous (when first reading it I understood it as 
"any part of C would include both A and B" which is wrong) and I would 
rather say something like
"(...) will draw the conclusions that the set of the parts of C includes 
both A and B."

" is_part_of_directly" I would prefer " is_direct_part_of" because it 
makes the reading of triples more natural: anA is_direct_part_of  aB


[Section: Choosing whether to use is_part_of or has_part]
"To say that 'All As are parts of some B' does not imply that 'All Bs 
are part of some A'"
Don't you mean that 'All As are parts of some B' does not imply that 
'All Bs HAVE for part some A'"

Wouldn't it be useful to introduce the inverse relation of 
is_part_of_directly / is_direct_part_of here ? (in fact I see it's done 
in one of the following sections)

[Section: Use Cases]
Wouldn't "geographical/spacial modelling" be a good use case too?

[Section: Pattern 2: Defining classes for Parts]
Font typos for " Part_of_car_directly subsumes" and "and that 
Part_of_car subsumes"

[General]
The <TITLE> of your draft is still "Defining N-ary Relations (…)"
