Well, only 4 weeks late with a reply....

I have been using a tool called Medius by Sandpiper Software[1], which 
is a Rational Rose plug-in.  They have developed scripts and Rose 
stereotypes for most of the DAML elements, along with wizards to guide 
the development of classes and properties.  The tool includes a DAML 
generator, so one can develop a model in Medius and then run a 
generation script to produce the DAML.[2]  I find that this is a better 
version of my previous personal ontology development workflow, which 
was to draw graphical models of the ontologies in ConceptDraw[3] and 
then type the DAML code in BBEdit[4].

Medius provides some standard upper-level ontologies and also manages 
the user's ontology library so that it is easy to extend or link to 
ontologies already represented in the tool.  Unfortunately, Medius 
doesn't provide round-trip engineering yet, so the tool itself must be 
used to input models for existing ontologies.

One of the things I like about Medius is the use of Rose's diagram 
features to produce graphics which can be used to present the ontology 

Disclaimer:  I am not affiliated with Sandpiper except as a user of 
their tool.

[2] While the tool doesn't produce OWL, there are OWL converters 
available.  I have used the converter available from Mindswap 
<http://www.mindswap.org/2002/owl.html> to produce OWL from the DAML.

advantage that it runs on Macs also.
