Hi, SpeciesAPI document http://www.gbif.org/developer/species specifies language parameter of simple get species, i.e. species/{int}. Language parameter is explained at http://www.gbif.org/developer/species#p_language as "default=en or use HTTP header for this", I tried to specify 'de' in HTTP header as Language request property, but it doesn't work. Instead, http://api.gbif.org/v1/species/5231190?language=de works fine. Do I misunderstand the documentation? I also tried languages are not included in vernacular names list http://api.gbif.org/v1/species/5231190/vernacularNames such as http://api.gbif.org/v1/species/5231190?language=ja or zh or kr... I expected empty field for vernacularName or no record returned, but I got English one. It is misleading implementation that one ignorant of the language specified can misundarstand that the language uses the same word with English. I suggest to return null vernacularName if vernacular name of specified language is unavailable. Cheers, James
