A metadata registry in action

I found this today while exploring use cases for the skos ontology looking for similarities to those for the cvcore. The NSDL Metadata Registry has some interesting features:

• it's based on skos
• it demonstrates a nice simple approach to the slowly-changing-time dimension , using a timeslice mechanism that allows the user to get a point-in time view of a resource.
• all resources are viewable as either HTML or RDF
• The developer blog gives an interesting insight into how the project runs.
  

Well worth a look for my NZ education sector friends :)
