Re: duplicate names reg

Hi Kala Devi,

I am afraid I don't understand what you men by names and duplicate 
names. Maybe you can reformulate your question and explain us what you 
try, and fail, to do.

For your information, identifiers in an ontology are unique (see URIs, 
IRIs). You can't reuse the same URI to identify two different entities, 
including entities of different kind, such as a class and a property. 
You can, however, use annotation properties on any entity (class, 
property or individual) to specify display names. The display names can 
be the same on different entities, although it may be confusing to deal 
with such ontologies. Also, it is recommended as a good practice that 
names of classes start with upper case letters, while names of 
properties start with lower case letters.

I hope this helps,
Csongor
