Ontology Naming Conventions

Greetings,

 

I'm working on an IT company, people and products ontology that is very
large.  I'm running into problems with naming properties because it is
difficult to not reuse the same names.  As a result, the names are getting
very long.  I was wondering if anybody would be so kind as to point me in
the direction of some ontologies that use longer names but are still
considered to be well structured and intelligent.  I need some inspiration.
Many thanks!  Regards, Kevin.
