I can only second Chris' statement "If you use a feature, all the time or not, that is not in OWL-lite, then use heavy OWL. "Removing" a feature from OWL-lite is not removing it from OWL." However, the argument for having two conformance layers is not only restricted to "cheap admission". In many cases conceptualizations will simply not require the given expressive power, consider for example WordNet or any other large thesaurus that have found broad user communities and may be called ontologies (since they establish shared agreement due to common usage). If we know apriori that only a limited subset of language features is used, different (considerably faster) evaluation strategies can be used in implementations. Third, the effort to learn the language is tremendoulsy simplified. Having a lower barrier for membership of the expected community will certainly increase the size of the community. Raphael
