Re: Main difference Frames and OWL-DL

My 2 cents worth:

In frames, each class is described by specifying (at least) a super- 
class and some attribute value pairs - such a specification is called  
a frame. There may be additional features such as defaults etc. The  
semantics is often not formally specified.

OWL-DL is based on a Description Logic, so it is a decidable subset  
of FOL with precisely defined semantics. Classes can be described  
using frame-like axioms, but the language is more flexible and allows  
for, e.g., multiple descriptions of a given class as well as axioms  
that establish (subclass or equivalence) relationships between two  
complex descriptions.
