The convention is to use the first element of the tuple as the keyword. (see the proplists module in stdlib). So, if 'title' is the only required parameter, I would go with something like this: albums_create(Title) -> albums_create(Title,[]). albums_create(Title,Opts) -> [..] where Opts = [Opt] Opt = {description,Description} | {public,Public} ...
