Most RDF vocabularies I've seen use camelCase for property definitions. In the AF model they can be defined with underscores to make them more ruby-like. Would it be possible to define these differently here, e.g.: `property :visibilityDuringEmbargo`

Also, is there a plan to provide an RDFS/OWL ontology at the URL http://projecthydra.org/ns/auth/acl?
