Deep Integration of Ruby with Semantic Web Ontologies
My presentation file needed a new home since the primary link that comes up in Google when you search for it is a ThoughtWorks server that no longer exists.
I'm also hosting a related whitepaper by Dominic Mainz from 2009
Deep Integration of Semantic Web Using Ruby (PDF, 7.7mb)
Incidentally, it's been about 6 years since I first took interest in this subject and I still think there's room for significant innovation here. Maybe I've read too much Neal Stephenson, but I can imagine people moonlighting as domain experts and maintaining a global commons ontological library that can be imported to form the foundation of your application's domain model just as easily as we import ruby gems today. A similar intellectual energy drove Wikipedia -- why not make it work for software models?
