Problem: How to describe commonly used terms for use in keywords and other bits of metadata so that we can all share a vocabulary?

Solution #1: CanCore

Solution #2: IMS Vocabulary Definition Exchange. A new project (I hadn’t heard of it until today, thanks to the CETIS article) that is aimed at defining a way of describing vocabularies to do just this… Poodle is a Dog is an Animal is Carbon Based…

Hierarchical bits of related, structured vocabulary data. This could be quite useful. The ALOHA team had to roll their own solution to this a while back. Maybe the next version will be standards based?
