Hi,

Copying Mayumi Koike, SC29 committee manager.

I'm sending this wearing my hat as the IETF's liaison to ISO/IEC JTC1/SC29, which includes SC29's WG1 JPEG.

It is my understanding that ISO documents can be shared in a liaison relationship, which we have here.  The IETF is a cat A liaison organization to SC29.  According to the ISO Directives (2021) (https://www.iso.org/sites/directives/current/consolidated/index.xhtml#_idTextAnchor095), section 1.17.2, subclause Category A, "[...] Such organizations are given access to all relevant documentation [...]".

Mayumi, can you please confirm?  For context, an RTP payload format for JPEG-XS under standardization in the IETF faces a hurdle in the approval process as it normatively references ISO/IEC 21122 and its subparts, and cannot be properly evaluated without having that ISO spec available.  What would be the easiest way to provide the IETF’s AVT WG with an appropriate copy?

Thanks,

Stephan

    This is a valid comment. We are unsure how to resolve this. ISO is very strict about distribution of documents outside of the working groups (i.e. it is not allowed at all).

    The ISO 21122 standards were written by some of the same authors as this RTP Payload spec (like myself and Thomas Richter), but the ISO documents were (to my knowledge) not shared.



    In order to resolve this issue, we need to know how IESG handled this with other ISO standards that are not open? Or is 21122 the first? Please advise.
