IETF79 Precis wg meeting minutes
Beijing, China
2010-11-08

Problem Statement
 issue 1: concensus: unicode code points, not UTF-8
 3 types of identifiers used by precis customers:
  a) compare byte-by-byte
  b) compare by a common algorithm that everyone agrees on
  c) No single common comparison algorithm for everyone
  (Specifically, everyone might want the comparison to be tailored for their locale, for some definition of locale)
 need to be able to sub-profile profiles so that you can build exception lists
 iri: don't care about this for now. iri is upper to precis.

RFCs Referencing Stringprep Review
 chairs to ping STORM working group about iscsi stringprep profile, and how much they care about case folding.
 question of NFC/NFKC/both/neither need to be transformed into dave's buckets.
 if we could all agree on "things that look like usernames" it would be good, so XMPP can align localpart with saslprep, etc.
 once there is a template, Alexey will review all of the saslprep-related RFCs

Review template brainstorming:
 Boxes
 Case folding; case sensitivity, preserve case
 User input
 Normalization
 Classes
 User exposed to
 published/seen
 security/authentication decisions
 Impacts of false positves and false negatives
 tolerance of changes in the community
 Delimiters such as .
