The portal use case starts with very good
motivational stuff, but when it gets to
the actual connection to an ontology language,
it seems to sort of go off a cliff...

  "In order allow more intelligent syndication,
  web portals can define an ontology for the community.
  This ontology can provide an expressive terminology
  for describing content, and inferences sanctioned
  by the ontology can be used to improve the quality
  of search on the portal. "

"inferences sactioned" is likely to be greek
to much of our audience. I suggest elaborating
the example:

  This ontology can include knowledge about the
  topic of the portal such as "academic
  papers are written by one or more authors,
  which are people; people have surnames
  and given names and affiliations, which
  are organizations" and so on. These
  rules might say that the surname, given name,
  and name of affiliated organization is
  sufficient to unambiguously identify
  a person in the community. That is the
  sort of inference that an ontology can
  enable.

The 2.2 Image Collections is nicely concrete.

Just an editorial suggestion:
use a list for the First/Second/Third
stuff. Web readers don't read; they scan.

regarding "2.3 Corporate Web Site Management"

it says "The requirements for this ontology are: ..."

I'd expect those bullets to link to
stuff in the requirements section.

But... we decided against making
"Part-whole relations" a requirement, no?
Similarly for preconditions.

Hmm... I see the "requiremtns for this
[use case] are..." under 2.4 Design Documentation
and 2.5 Intelligent Agents too. Again,
without links to the requirements section.

The Constraints stuff... did we agree that's
a requirement? some of it was, some of it
wasn't, as I recall.
