Some notes on the OOR slides:    (01)

  Suggest that if you keep the SemWeb comments on slide 6
  that you improve and expand them by discussing how
  ontologies are different then web pages and the issues and
  subsequent characteristics necessary for ontological content
  to be reused.     (02)

[New bullets under the SemWeb approach to replace "History does...":]
  - The "clickable" web has been very successful in employing this
    strategy for html documents
  - However the use and content of the semantic web has different
    characteristics that make it far less tolerant of the change
    and frequent errors which are commonplace on the clickable web.    (03)

  Distinguishing characteristics of the semantic web    (04)

  - Machines rather than humans are the primary consumers of
    content. Errors that a human may be able to diagnose and fix (such
    as a change in location of a document) are likely fatal for
    machine processing    (05)

  - The use of owl:imports creates a strong transitive dependency
    between ontology documents; changes in any imported document
    (imported directly or through nested import) can cause the
    resulting import closure to be inconsistent or to change its
    meaning or computational characteristics significantly.    (06)

  - Ontologies convey a precise meaning with an unambiguous machine
    interpretation.  This means that, when using this content, careful
    selection and precise reference is critical.    (07)

[move the remainder of the material (starting with the bullet: So real
rationale) currently on slide 6 onto a new slide.  Get rid of the
"So real..." bullet text and entitle the new slide:]
Ontology content management features added with a repository    (08)

[Delete the current bottom two bullets]
[Add bullets:]
- It's reliably available
- It's location will persist, so you can be confident when
committing to its use
- It's got information about when, why, and how it has changed, so you
can be aware of changes that may effect its usability    (09)
