Hello, Thanks for your answer. In my first email on this thread I explained what I was trying to achieve:
I'm using Jena rhrough Fuseki from a Ruby on Rails web app, now I want to add Spin to the stack so I can force some constraints on the insertions. What you said in your last paragraph is exactly what I want to do, and yes, the example I pasted is from Spin's distribution.
