I'm afraid a full description is not possible, it would take
too long. Ontopia offers workshops covering this kind of thing,
and the *minimum* length is one whole day (assuming knowledge
of the basic topic map concepts).

The short answer is that the ontology of the Italian Opera
topic map was developed by someone who (in some measure) is
a domain expert. Ontologies cannot be developed by non-experts.
Part of this work involved examining the documents, but most
of it came from an intimate knowledge of the subject area.

The basic process is as follows:

- delimit the scope of the application
- brainstorm relevant concepts, including examination of
  documents, if available
- organise result into topic types, association types, occurrence
  types, and individuals
- revisit each typing topic and refine the ontology along certain
  principles

 From this point it is possible to start populating the topic map,
either automatically (if your basic set of information is sufficiently
well-structured) or manually.

Sorry this is only a bare outline. Come to the "Modelling Topic Maps"
tutorial in Montreal if you want the details :-)
