Wilbur is Dead - Long Live Wilbur!

As many of you have quite correctly concluded, we are no longer actively maintaining Wilbur at Nokia. Today I have released what tentatively is the "final" Nokia release of Wilbur, available here as a gzipped tarball. The release is merely the current development snapshot that I have been using for some experimentation, but (and this may be significant to some folks) we also changed the Wilbur license to LLGPL.

The Wilbur toolkit is now at least 10 years old, and during its lifetime the project yielded one Ph.D and almost a dozen conference papers. It also served as a foundational experimentation tool and helped us develop a better understanding of the problems and solutions of RDF processing and storage. The spirit of Wilbur will continue to live on in the Piglet toolkit, released as part of the Smart-M3 system.

I will continue to answer questions about Wilbur should somebody have any...

RIP Wilbur, you served us well. Long live Wilbur 2 with its dynamic, default logic deductive closure calculator ;-)

I think technically that would be "Wilbur 3"... but for now, that's really what the next stage of Piglet could be. In a way, what's happening here is that this "RIP Common Lisp" :-(

It could be very interesting to hear from you why you moved away from Common Lisp! I am a PhD candidate developing deduction systems for ALC/ALCQ. I have already developed a small prototype using Maude and I was thinking to move to Lisp.

Hmm... why I moved away from Common Lisp...? That's gotta be the subject a future blog post.

That smart-m3 page needs a home page with some information about the project. My interest is piqued, but no enough to download and start reading source without an introduction.

Looking forward to hear about why you have moved away from CL.
