I agree that having unadorned values likely simplifies things in many cases,
but if we do this, we should let the Client say what language/script it’s using
when providing human-readable strings or references to them as registration
parameters. For this purpose, I’d propose that we have a parameter something
like this one:
registration_locale
OPTIONAL or REQURED. Language and script used for human-readable values or
references to human-readable values that are supplied without language/script
tags, represented as a BCP47[RFC5646] language tag value. This parameter is
REQUIRED if any human-readable values or references to human-readable are
provided without language/script tags.

Subject: Re: [OAUTH-WG] Registration: Internationalization of Human-Readable
names
On the surface this does simplify things, but the issue I forsee with it is
that I want to be able to call "client.getClientName()" and always get
*something* out of it if there are *any* client_name fields at all. So in this
world if I take a client library that assumes en-us and it talks to a server
that only looks for es-cl, there's a very real chance of the client name not
getting set at all. I think that's a problem.
This is why I think the default field name (without the language tag) really
should be required and should be left undefined as to what language and script
it is. Essentially, "It's a UTF8 String, hope for the best". If you want
something more specific and smart about localization, then you can support the
language tags. If you just want to have a string to store and throw at the
user, then you can just use the bare field name.
In other words, we take what we have now (which works for a
non-internationalized case where everyone just assumes a common
language/script), and we augment it with features that let it be smarter if you
want it to be smarter. Make the simple case simple, make the complicated case
possible.

As a simplifying option... why not just require human-readable fields to
require a "script-tag". This way it is always explicit what language/locale the
text is for. It then becomes the responsibility of the AS to return an
appropriate response if there is not a direct match between a request and the
data stored at the AS (and out of scope of the spec).

So with what little feedback I've gotten, I'm proposing to add text from the
proposed webfinger and OIDC drafts for the hash-based localization of strings,
with the following properties:
* All localized versions of fields are fully optional on both client and server
* If a localized version of a field is included, its bare-value (perhaps
internationalized) field MUST be included
* All human-readable fields are eligible for this mechanism (including any
uri's for user-facing web pages, which can be used to point to
language-specific pages)
* Clients and servers can decide to use whatever language/script they want to
for the bare-value field, and no assumptions can be made on either side about
what that is
I think that with these constraints, we can add functionality to address
Stephen's concerns without getting too complicated or putting too much burden
of support.

Paul is proposing the same syntax as Connect.

It does presume a definition of "claim", which I suppose we could turn to
"metadata field" for DynReg and its extensions to be appropriately limiting.
But we also need a good definition of what a language-tag-less field means, and
whether or not it's required if the other fields are present or not (which is
something that Connect is trying to fix at the moment, as I recall from last
week).
So it turns into about a paragraph worth of text. Is that worth it? I'm not
entirely convinced that it is, but I'm interested to hear what others think,
particularly those who *aren't* tied into the OpenID Connect protocol so much.
(I don't want to pick a solution just because it's familiar, if we need a
solution at all.)

My concern with this is that OIDC can get away with defining this
multi-language structure because it defines the mechanism once (in Messages)
and applies it to all user-readable strings throughout the whole application
protocol, of which there are several. Do we really want to pull in that whole
structure and mechanism for one field in client registration? I really don't
think it should be something that's defined completely inside of DynReg for a
corner case for a single field, but I also doubt we want to normatively point
to OIDC Messages for this solution either.
There are also other ways to do this: Webfinger [1] for instance uses JSON
structures to give language tags to field values, and has a default mechanism:
{ "en_us": "my client", … }
The fundamental question is this: should a client be able to register multiple
names (in different locales) with a single client_id, or should it get a
different client_id for each display language set?

That is what I was thinking. It would be up to the AS to determine what
language and script to present based on the user preference.
While a large number of clients will be native and might be able to customize
themselves for a single user during registration , we don't want to forget the
web server clients that are multi user.

FWIW, the closely related OpenID Connect client registration draft does have
some support for doing this, which could maybe be borrowed. See client_name in

It was brought up at the in-person meeting today that we'll want to consider
issues around internationalization and localization of human-readable fields
like client_name in the client registration. Which is to say: if a client
supports ten languages and wants to present itself in ten languages, should it
have to register itself ten times with an AS?
At the moment, I'm of the opinion a client with ten languages could register
itself ten times, or do something with the context in which it runs to
determine which human-facing language to use. Keep in mind that in some cases
(such as native clients), you'll be dynamically registering a client for each
user, in effect. In other words, I personally think that this is a rathole that
will cause more harm than good.
