Holger, When I saw this message I went to the console (hadn't thought to look there before) and saw a warning: "WARN URI <http://siemens.com/schemas/activity#commonLabelURI> has no registered function factory", which I am assuming is directly related to your question. I was not aware that I had to do something special to register SPIN functions. As you can see, were not in a file named foo.spin.ttl (but they are now).
I am unclear about where I would make the call you suggest. Jack On Wednesday, March 4, 2015 at 3:19:22 PM UTC-8, Holger Knublauch wrote: > > Jack, > > are you sure the SPIN functions are registered?
