The attached might be an ad, but I present it as a counterexample to 
what I said earlier (to Jyoti).  SWRL apparently lives!
[The words "academic spinoff" and "government-sponsored" may nonetheless 
apply here as well. ;-)]    (01)

Ed,    (04)

Someone from the ontolog forum forwarded this to me recently, where
you said:    (05)

I just wanted to point out that my company [1] is commercially
supporting and developing a SWRL implementation in Pellet, our OWL

commercially, for both government and commercial clients.    (07)

You might enjoy the recent series of weblog posts about our position
re: SWRL and DL Safe Rules on our weblog [2].    (08)

We're very active in the HCLS area, where interest in SWRL and DL Safe 
Rules is very high. We've also been responsible for the OWLED [3] 
workshops, where interest in SWRL in the context of OWL is always high.    (09)
