#pref_label ⇒ Object

returns the (one!) preferred label of a concept for the requested language. lang can either be a (lowercase) string or symbol with the (ISO .…) two letter code of the language (e.g. :en for English, :fr for French, :de for German). If no prefLabel for the requested language exists, a new label will be returned (if you modify it, don’t forget to save it afterwards!)
