We have 30 RDfizers written at different points in time.

If an RDFizer is imperfect (like most of LOD) simple feedback will do. I

If OpenLink has one attribute, I don't think  "static" would be the one 
:-) These cartridges changes on a daily basis depending on a myriad of 
circumstances (including feedback).

As with all things, feedback would be very helpful.
