Dave McComb of Semantic Arts is a good resource to tap for ontology design.
The 2009 Semantic Technology Conference will be held in San Jose, June 14-18
An interesting tool for developing ontologies: Swoop
"SWOOP is a tool for creating, editing, and debugging OWL ontologies. It was produced by the MIND lab at University of Maryland, College Park, but is now an open source project with contributers from all over."
Protégé is another free, open source ontology editor and knowledge-base framework worth considering.
The following article resources may be of interest to others that are unfamiliar with Canonical models and ontologies.
IBM DeveloperWorks published a series of articles in 2007 that may be of some interest (in particular, "Web services and the semantic Web, Part 3: Understand RDF and RDFs" and "Web services and the semantic Web, Part 4: Create an ontology")

The CO-ODE project aims to build authoring tools and infrastructure that make ontology engineering easier. We specifically support the development and use of OWL-DL ontologies, by being heavily involved in the creation of infrastructure and plugins for the Protégé platform and more recently, OWL2.0 support for the OWL API.
Many of our collaborators have come from the life sciences community, but we aim to support as broad a range of users as possible - researchers, librarians, industry, and the Semantic Web community
In support of this work the team have also been involved in organising tutorials and workshops on OWL.
The project is supported by JISC and is a collaboration with Stanford University
