Re: [arch-d] Proposed IAB program: Evolvability, Deployability, & Maintainability.

Brian:

I thought to remember tht Warren mentioned last year some interest
in new processes for "living documents" primarily in OPS. Have
not tracked enough mailing lists to know if/what is happening (if anything),
but i agree that those different type of document lifecycle models
would be crucial to tackle the topics proposed.

But i think it would be perfect to simply learn by doing, and not
bother too much about FIRST working out the document structure and THEN
commit the payload.

Aka: this could be a good set of topics for a living-document-hackathon.

Cheers

In particular, does the way we handle document revisions and interdependencies make it harder for implementors and operators do decide which features to implement and deploy? Why don't we issue many more of what RFC2026 calls "applicability statements"? Why don't we issue living documents that define which documents are part of a particular standard at a particular time?

This group will work on documents that catalog and analyze successful strategies for protocol evolution, deployment, and maintenance, such as updating and extending RFC 6709. Moreover, it will focus on ways to help promote and increase awareness of these strategies within the IETF via program meetings, workshops, and helping organize efforts within working groups and various IETF teams. The program will include members of the IESG and the tools team to help implement these strategies.

Make it easy for people, especially those who aren???t steeped in IETF process, to know which extension points are the right ones to use for a given protocol (and which ones should be considered more stable/ossified), and make sure there aren't high allocation barriers to use those extension points.

Look at methods to catalog implementations, tools for tracking interoperability testing on different protocol versions, or repositories of which versions of protocols are implemented and used on the Internet. Discuss how deployments can advertise experiments they are running.

Help promote consistent ways to host non-RFC working group output, like FAQs, wikis, and discussion venues. Consider how this community involvement can continue and involve the right experts, even after a working group closes.
