[NTG-context] Better option for a macro with lots of arguments

I have been using the following macro to add a bunch of sections to the
start of chapters in a book, it works but I think is kind of weak:

%%%%%%%%%%%%%%%%%%%

\define[7]\metadatos{
  \startsection[title={Resumen}] #1 \stopsection
  \startsection[title={Palabras clave}] #2 \stopsection
  \start
  \language[en]
  \startsection[title={Abstract}] #3  \stopsection
  \startsection[title={Keywords}] #4 \stopsection
  \stop
  \startsection[title={¿Cómo citar este capítulo? / How to cite this book?}]
    \startsubsection[title={Apa}] #5 \stopsubsection
    \startsubsection[title={Chicago}] #6 \stopsubsection
    \startsubsection[title={MLA}] #7 \stopsubsection
   \stopsection
}

\starttext
% Then I call the macro like this:
\metadatos{spanish abstract \input knuth}{some, comma, separated, keywords,
in, spanish}{english abstract \input knuth}{same, comma, separated,
keywords, in, english}{Apa citation style for this article}{Chicago
citation style for this article}{MLA citation style for this article}
\stoptext
%%%%%%%%%%%%%%%%%%%

I've been exploring different ways to do it better, but with not much luck,
I was thinking something based in key=value assignments? setups? datasets?
Not really sure, but If you know a better solution or point me in the
direction of something I can use to replace that macro, it would be greatly
appreciated.

“You develop an instant global consciousness, a people orientation, an
intense dissatisfaction with the state of the world, and a compulsion to do
something about it. From out there on the moon, international politics look
so petty. You want to grab a politician by the scruff of the neck and drag
him a quarter of a million miles out and say, ‘Look at that, you son of a
bitch.’” — Apollo 14 astronaut Edgar Mitchell
