Well, I don't agree with that. However, it is a key feature.

But even so, it's not like people were hiding Galen. Where's the big  
example? People are telling me Ontoprise has some industry ones  
hidden away... it'd be nice if there were at least stats and a write  
up or three.

I'm skeptical that is a major contributer. Plus, neither explains the  
absence of "showcase" ontology and F-Logic using projects a la Galen  
or Snomed (or DL using systems like NCI before it went OWL).

Granted, Apelon doesn't have a lot of public ontologies that I can  
easily see, but the papers are at least suggestive:

Plus there were repositories, however "eh" (e.g., the DAML ontology

Erhm. RuleML has been around. SWSL-Rules. WSML. Plus again, I'm  
looking for the big exemplars. I understand that Ontoprise has some,  
so maybe there's a write up somewhere.

Yes, but there's been "real" prolog repositories (programs, not  
ontologies) for years, e.g.,


not to mention the often extensive libraries bundled with Prolog  

Even CLIPS has some interesting examples:

(Not to mention all the written up projects.)

Anyhoo. It'd be great if some F-Logic folks could put together a  
resource page on actual use (not that this is easy! but the dearth is  
depressing to me)

Valli pointed me to:


So I'll keep poking.
