Hello all,

I just joined this list, my name is Martin Matthiesen and I am currently
co-ordinating the Clarin AAI Taskforce, where we try to tackle AAI
interoperability within Clarin.

I would argue against an EC for commercial IdPs. I cannot immagine a use case
where a resource or service can be open to hundreds of millions of potential
users from universities but has to be carefully guarded from users in
companies and Terms of Use are not sufficient. In my view such a resource is
either public or requires individual access, where I would trust the IdP from
a big commerical company probably more than the IdP from a small regional
university with an understaffed IT department. I would also trust the users
from commercial companies more to use resources responsibly and respect ToS
than 18 year old first-year students.

Protect Network is a special case, though. But I don't see the commercial
aspect here as the problem, rather the question on how users get accounts,
which is a bit unclear to me. If it is really "public sign up" and the level
of assurance is thus zero, I don't see why anyone would want to have it, with
or without EC. In Clarin we have a similar IdP for homeless users, but have
not registered that to eduGAIN for good reasons. I understand Protect Network
is IdP outsourcing, which makes a lot of sense.

Clarin does have a use case for resources that are automatically open to
academics, Clarin ACA (www.clarin.eu/content/license-categories). This
category is implemented in Fin-Clarin for a newspaper corpus (HS.fi,
https://korp.csc.fi/#lang=en). It requires the eduPersonAffiliation attribute
to be set to "faculty". I am not very familiar with eduGAIN legalese, but I
would assume that non-academic IdPs are not allowed to set eduPerson*?

I'd be happy to join in as well.

I had two foreign users from Sweden and Norway trying to access the "HS.fi"
text corpus mentioned above and both professors could not get access because
their EPA attributes were lacking the "faculty" attribute, otherwise clearly
required by Feide and Swamid. This was corrected in one case and the user got
access. My argument against another EC is also practical: It will take a long
time to get the definition right and then an even longer time until all IdPs
have implemented it. And as said above, I don't see the use case.

Regards,
Martin
