Yes. I saw that. Thanks to all of you who send tools indications are 
It's not easy task for new comers to find out the right orientation as 
to what parts of the technology and tools are readily usable for 
practical and *standard compliant* applications. My take-over of this 
thread is that Turtle syntax and Sparql form the most stable basis for 
SW applications development. N3 rules is more bleeding-edge stuffs, not 
necessarily supported across the board expected by cwm, which in a sense 
is an N3 reference implementation. But, there is no guarantee it'll be 
retrofitted as is in the SW standards. Jena is interoperable with Turtle 
and Sparql and is a (the?) framework of choice for Java programmers. 
Though, it is not compatible with N3 rules but provide reasoner 
alternatives. Did I get this right?
