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)
