[Medup] Issues draft-birk-pep-trustwords (was: New Version Notification for draft-birk-pep-trustwords-03.txt)

[Bernie Hoeneisen <[e-mail]>]

Dear MEDUP list

The IANA Registration for trustwords (a basic concept applied in pEp)
https://www.ietf.org/internet-drafts/draft-birk-pep-trustwords-03.txt
has several open issues, we'd need your feedback on, e.g.:


1) Localization:
    How should non-ASCII-7bit letters or language symbols be represented
    in the wordlists? UTF-8? HTML-like encoding? IDNA? Any better solution?


2) Registration format:
    The format for registrations of at IANA is normaly (peudo-)XML.
    While XML is concise for registering wordlists, the files
    for registration will contain lot of XML overhead and thus get rather
    long. Is this an issue? Use another format, e.g. CSV?


3) ISO language code:
    Which ISO language code either 639-1 or 639-3 shall be used, to
    designate the language, i.e.,
    ISO-639-1 (e.g., ca, de, en, ...) as currently used in pEp
    implementations (running code) or ISO-639-3 (eng, deu, ita, ...)
    With ISO-639-3 more languages can be addressed, in particular
    less widespread languages and dialects.


4) Bitsize (how many bits can be mapped with a wordlist):
    e.g. a bitsize of 16 allows for a list containing 2^16 = 655536 words.

    Should this be kept open or should only certain values for bitsize
    be allowed to be registerd?
    If latter applies, which values are useful (e.g. 8, 12 and 16)


Looking forward to your input!


So long!

  Bernie
