Modeling as a class vs. an instance of a class #12

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Topic or term(s) which needs clarification:

It is possible to model resources as many classes or as many instances of a few 
classes.  There are tradeoffs which, depending on the circumstances, make one 
approach more suitable than the other.

Once a decision is taken on the issue of many classes vs many instances, it is 
worth examining whether one or the other of the standard OWL2 profiles can 
profitably be enforced on the ontology.  See 
http://www.w3.org/2007/OWL/wiki/Profiles and 
http://owl.cs.manchester.ac.uk/validator/

My reading of the Profile descriptions, especially in the cited wiki page, is 
that EL (resp QL) will do better with a large number of classes (resp of 
instances.)
