Our intention is to support permission based access to the REST API via an
"authenticating proxy", which we call lemme:

https://gitlab.com/mailman/lemme/tree/master

and for an outline on how this might work:

https://gitlab.com/mailman/lemme/blob/master/OUTLINE.rst

We had good discussions about this at Pycon 2016, but haven't gotten very far
in implementation details.  I'm hoping we can spend a little bit of time on
that this year.

Cheers,

Agreed, but note this is only one half of the equation.  You also need to
publish the static definition of the REST API so that HTTP clients could
discover it.  That's my understanding of the role that WADL serves.

This would also go well with an idea I had about the current state of
the REST API and encrypted lists. With having decorators like
"@exported_REST", another one could get introduced, something like
"@requires_permission("some.perm.name")" which would introduce
permission-based granularity to the REST API. Then multiple
user:password pairs could be specified in a config with different
permissions and so Mailman could provide different levels of API access
to different apps.

Although, reading Barry's message again, this may not be possible /
maintainable.

That sounds cool, but I tend to feel that WADL gets pretty heavy.  If
we can't just mark things with something like "@exported_REST", it's
not clear that the maintenance burden is worth it.

To the contrary, I think if it were possible it would be pretty nice.  In
fact, you could conceivably eliminate mailman-client if you could do it, and
other languages could auto-generate bindings to the REST API.  I haven't kept
up on the state of the art, but IIRC, there were Python libraries that could
generate bindings based on WADL.
