Training Drupalcon

I've found some posts in this group from March indicating that there was an OpenPublish training session at DrupalCon SF. Does anyone know if this session was videotaped, audio recorded or had presentation materials? I am particularly trying to understand:

• The role and use of the many Taxonomy vocabularies in OP.
• How to add new Features (i.e., content type and views and vocabulary for new functionality) to OP.

Thanks.
