Useful to those active in the domain you spoke of, of course. (03)
And there are usually many subdomains in any domain, thus
sub-ontologies in any larger one, each one focussing on the essence of
the subdomain it targets. Nothing really difficult at all, as long as
modularity - that age-old strategy of "divide and conquer" - is fully
embraced (architecture permitting...), and the fine granularity of
human activities (workflow, enjoying, living, learning, etc) is taken
up appropriately. (04)
The big problem arises if one ever tries to be "complete" about
anything. (05)
