Re: [ontolog-forum] multidimensional surfaces

[Deborah MacPherson <debmacp@xxxxxxxxx>]

Why talk of multi-dimensional surfaces then exclude what would make a texture like spatial extent and density pushing those surfaces around? Your example of two conceptual works having the same author, would necessarily change the dimensions and surfaces of some conceptual models.

Conceptual entities are often ontologized -- conceptual works, accounts,
obligations, etc.  I would not model these with a spatial extent or
location.  Relations among such conceptual entitites would seem to me to
be exclusive of space.

I would consider integers and fractions as being outside of space and time,
yet well described in terms of finite objects existing in space and time.

The relations often originate in spacetime concepts -- but relations also
exist among aspatial concepts: two conceptual works having the same author,
for example.
