Re: [Last-Call] secdir review of draft-ietf-jmap-quotas

[[e-mail]]

Hello all,

Apologies I've been quite off for the last month or so as well. Like Wes, well numerous life events in my case too.

But I should now have time again to address soon enough the concerns I got. I will answer Wes concerns but also everybody else that took the time this last month to review and comment on the jmap quota draft.

Just bear with me a bit longer and we should be fine I believe :)

Best regards,

Rene.

On Jan 18, 2023 6:22 AM, from Bron Gondwana Rene, can you please address this review.  Hopefully we're close to ready now!

Thanks,

Bron.

Review summary: almost ready with issues

Apologies for my delay in getting to the new version of this document
(between vacation and a bad cold, I got behind in tasks).  Thank you for
the work you put into the new version; I find it much better than the
old and can see you took many suggestions (mine and others) into
account.

A few (mostly minor) thoughts on the new version:

- If it were me, I'd break the quota attributes section into it's own
  (becoming a new 4.1) starting with "The quota object MUST...".

- 4.1: document at section 5.1 -> document in section  5.1

- 4.3: any of which may be omitted -> any of which may be included or
  omitted

- 4.3: seems odd that the name attribute is the only one that isn't a
  list.

- 4.3: Larger issue wrt interoperability: My last note leads to the
  next: in the summary paragraph you state "A Quota object matches the
  FilterCondition if and only if all the given conditions match,
  including multiple array elements existing within a condition.", which
  I don't know how to interpret properly.  You say that all conditions
  match (which I'm sure means if both a scope and a resourceType are
  specified they both MUST match).  But the second part of the sentence
  leaves me confused about multiple array elements.  This would leave me
  to think that if you specified multiple resourceTypes in a list, then
  every type must match which should never be true so I doubt this is
  what you mean.  Maybe this is a good rewrite:

      A Quota object matches the FilterCondition if and only if all the
      given properties match (i.e. a logical and of all properties).
      For filter properties that are a list, at least one of the list
      elements must match for that property to be considered a match
      (i.e. a logical or of all the property's list element).

  But...  I am trying to figure out what you mean, and my interpretation
  may be wrong!

- For the example in section 5.2, I'd suggest actually using data that
  followed the previous example in a time-sequence.  Thus, if you
  changed the "sinceState" to "78540" to match the last value from the
  previous example, it would better show an example of commands over
  time.  (IMHO)

- The security section is improved (thank you), but there are some
  wording issues within it that need work:

    - "so he shouldn't know" -- I think you mean other users here
      shouldn't know.  So I'd change this to "so other users shouldn't
      know" or "no users should know".

    - The last sentence is hard to read as is.  I'd suggest the
      following replacement:

      In order to limit those attacks, quotas with "domain" or "global"
      scope SHOULD only be visible to server administrators and not to
      general users.

- I'm surprised you don't have an acknowledgment section, which
  customary to list all the people that help you put this specification
  together.  It's common but not required of course.
