I'm glad to have the opportunity to talk to Ontolog
today, and I have two points that I want to leave with
you, together with some supporting details:
  - The Topic Maps saga, which began in 1993, teaches
      that powerful subject-based indexing of
      information is so compelling that it sells
      itself.  In subject-based indexing, entries in
      indexes are designed to be findable, and, once
      found, each listing has all that's known about
      that particular subject.  Customers typically
      react quickly and positively to subject-based
      indexes of their complex information resources.
      They see the value proposition intuitively; it
      speaks for itself.  The selling power of it is
      awesome.  Among other things, it compels
      customers to acknowledge the importance of
      careful thinking about ontologies.  It compels
      them to buy ontological services.  It's good
      business for people like us.
- I have a special message for you if you must
      maintain a specialized ontology and, at the same
      time, you must demonstrate that there is a
      straightforward way to integrate your knowledge
      with diverse other knowledge resources whose
      ontologies, if any, are not under your control.
      My message is that there is a useful approach,
      that not only provides political cover, but also
      happens to work.
This talk has 2 take-aways:
  - Topic Maps powerfully sell ontological services.
- The Topic Maps Reference Model provides a way to make the integration of diverse knowledge, expressed in terms of diverse ontologies, straightforward.
Consultants and ontological engineers, take note!
The rest is detail.  Here are some details.
