Dear all,

I tend to agree with Andy here.
What are the key advantages to have some YANG tree diagram rules here? We never know in advance what people are looking for in that full tree. Sometimes, it's a simple grep.
And if it's too long/not useful, people will simply skip it
We are not even saving trees, as (I guess that) people don't print out RFCs any longer.

Regards, Benoit

Hi,

IMO we do not need new procedures to save the
reader from a few extra pages of YANG tree diagram text.

This is the only option that makes sense to me:

   *  Include the full tree in an appendix.

        Hi Lou, Kent, all,

        Taking into account the feedback received so far, I suggest
        the following change:

        OLD:

           YANG tree diagrams provide a concise representation of a
        YANG module

           and SHOULD be included to help readers understand YANG module

        structure.  If the complete tree diagram for a module becomes long

           (more than 2 pages, typically), the diagram SHOULD be split
        into

           several smaller diagrams (a.k.a subtrees). For the reader's

        convenience, a subtree should fit within a page.  If the complete

           tree diagram is too long (more than 5 pages, typically)
        even with

           groupings unexpanded (Section 2.2 of [RFC8340]), the
        authors SHOULD

           NOT include it in the document.  A stable pointer to
        retrieve the

           full tree MAY be included.

        NEW:

           * Provide only a stable pointer to retrieve the full tree. 
        The full

        Hi Lou,

          * Keeping long trees in the main document is really not
            helpful to digest a module. I also know by experience that
            this raises comments, including from the IESG.
          * Keeping long trees that exceed 69 line max in the main or
            as an appendix is really hard to follow.
          * There are already RFCs out there do not include long
            trees, but a note about how to generate it. The narrative
            text uses small snippets to help readers walk through the
            model.
          * Some consistency is needed in how we document our modules
            + help authors with clear guidance (e.g., characterize
            what is a long tree)

        I’m afraid that we can’t simply leave the OLD 8407 as it is.

        That’s said, I’m only the pen holder and will implement
        whatever the WG decides here.

        Cheers,

        Med, Jan, WG,

        I have to say that I read the discussion concluding with to
        NOT change the current recommendation,
        
seehttps://mailarchive.ietf.org/arch/msg/netmod/0Q0YiyNi15V-Szzf5awLVh-15_c/

        I personally use an ereader (or computer) more than paper and
        having to go to a static URL -- probably when I'm off line --
        does NOT seem like something we should be recommending. 
        Furthermore, I'm not sure what our process has to say about
        having the HTML include *text content* that is not in the text
        version.

        Again just my perspective.

        What do others think? do they feel strongly that this change
        from the current recommendation (in RFC8340) of having long
        trees in appendixes is a good or bad idea? (Yes, I'm in the
        strongly against camp.)

        Thanks,

        Lou

            Hi Lou,

             1. The comment that triggered the change and companion
                thread where this was discussed and changes proposed
                can be seen at:

            
https://mailarchive.ietf.org/arch/msg/netmod/-b2HX0XUK49qJB19LHu6MC0D9zc/.

            Please note that for html version can still include the
            long tree,

            The tooling may evolve in the future to provide better
            rendering

            of too long trees.  This tooling may offer (but not
            limited to),

            unfold trees, control of expanded views, ease navigation among

            various levels of a tree, support of hyperlinks, etc. When
            such a

            tooling is available, too long trees can be displayed in
            the HTML

            version of documents that include such trees.

             1. The candidate change was shared with the WG prior to
                
IETF#119:https://mailarchive.ietf.org/arch/msg/netmod/x9aex0PO-KARyg5FtzjLNYrIpLY/

            Hi,

            I have a late comment as contributor on this draft (based
            on a co-chair discussion).

            Looking at the diff relative of section 3.4 to the
            original document, I think the idea of referencing a URL
            versus an appendix is a bad idea. The new text in question:

            " If the complete tree diagram for a module becomes long
            (more than 2 pages, typically), the diagram SHOULD be
            split into several smaller diagrams (a.k.a subtrees). For
            the reader's convenience, a subtree should fit within a
            page. If the complete tree diagram is too long (more than
            5 pages, typically) even with groupings unexpanded
            (Section 2.2 of [RFC8340]), the authors SHOULD NOT include
            it in the document. A stable pointer to retrieve the full
            tree MAY be included."

            I prefer the original
            inhttps://www.rfc-editor.org/rfc/rfc8340#section-3.3which

            (a) does not have conformance language and

            (b) keeps the information as available as the document
            itself by including the long diagram in an appendix.

            I would like to see this section reverted to the original.

            Authors,

            What is the motivation for the change to URLs and making
            this a "SHOULD NOT"?

            Thanks,

            Lou
