I often have thought the same thing.  Folks working on ontologies tend to focus on philosophical issues of conceptualization, i.e., painting a detailed picture of the "things" involved.  This quickly leads to problems because, to the extent that the world actually can be understood via "classes" and "properties", domain experts simply do not agree on what these classes and properties are.  Yet one of the (frequently implicit) assumptions of ontology-building is that the domain experts have an agreed-upon description of the world, or they can talk themselves to the point of having one.  

The alternative is to focus on the process of reasoning from inputs to correct outputs, i.e., test-driven ontology development.  Perhaps domain experts would agree much more thoroughly on what inferences are valid, and what ones are invalid, from a given set of inputs.  In an ideal world, the domain experts would provide a rich set of hypothetical information inputs, and then they would provide a rich set of inferences from them, and perhaps an equally rich set of invalid inferences, and then the knowledge engineering folks would build the ontology to avoid all the invalid inferences and support as many of the valid inferences as they can (until the money runs out).  

Are there any examples of this approach?

Who is it for? What will it enable them to do? Do they want/need to do it?

I'm thinking a really good session with a basic UML tool would be a big step forward.  I have got hold of a UML tool and intend to have a go at a core tdwg model.  I think it would be great then if we could organise a session on working on this model.

Well stated Stan, but I'd add a third-

3. Effective tool/s for viewing (graph, sub-graph, tables, properties etc.),
add/delete/modify with adaptable governance control (e.g., assigned management
to sub-graph domains), annotate (with full logging of who did what, when and
how...). This is in effect a collaboration tool.

Until we have a tool (preferable to tools) that can be intuitive and effective
for building, managing and deploying /exporting vocabs or ontologies, we will
struggle with this socially and technically tough, but very necessary task. The
social issues are the hardest, but an effective collaboration tool would be a
big help.

A tool that will be readily embraced  by #2 (the domain specialists) seems far
more important than the tools I've seen so far that are embraced by #1 (e.g.
Protégé).

That we don't have a TDWG ontology is an increasing worry.

Progress on the TDWG ontology seems to require:

1) one or more people with good sense of what can be done with ontologies, both
in the near-term and long-term; and
2) one or more people who understand the way information is partitioned in this
domain and how it could fit together.

I think we have a lot of #2, but not many of #1.

FYI, we have seed money to bring these categories together.
