Don't want a map? Use the verl_parser module...

    1> verl_parser:parse_version(<<"1.2.3">>).
    {ok,{1,2,3,[],[]}}
    2> verl_parser:parse_version(<<"1.2.3+build">>).
    {ok,{1,2,3,[],[<<"build">>]}}
    3> verl_parser:parse_version(<<"1.2.3-pre+build">>).
    {ok,{1,2,3,[<<"pre">>],[<<"build">>]}}
    4> verl_parser:parse_version(<<"1">>).
    error
