Review of OWL syntaxes

This is a review of OWL syntaxes.

The article clearly explains the different syntaxes, with their strengths and weaknesses. It would be useful to know which syntaxes are used by whom (typically), for example, it’s not clear who the functional OWL syntax is used by. If it is not an exchange syntax, is it primarily for software, specifications or end users building ontologies?

The article would benefit from a short abstract and conclusion.
