I don’t want to speak for Dimitris here but perhaps he is referring to the 
totality of the tasks required of the Chair? He has done a great job in 
organizing and semi-automating many of the menial tasks that Chairs have to do. 
Nonetheless there are still many tasks that add up so I can see where he was 
trying to save some efforts in combining these two.

 

But as pointed out, there are pros and cons to this combination. Any work that 
members can do to help further automate these processes would be greatly 
appreciated.

I think you have a point about A + B, so we should have independent review 
periods for each ballot as we did with version 1.6.4 (we had independent 
ballots to be reviewed and then a combined/aggregated new version of the BRs). 

I also received some personal messages supporting the "aggregated" practice as 
it seems to be much more efficient for a CA's compliance review to check 
against one new BR rather than 2 or 3 separate ones within a very short 
timeframe.

More answers inline.

The act of combining ballots is relatively new, as you can see from 
https://cabforum.org/baseline-requirements-documents/ . Producing multiple 
versions of the Guidelines, linear based on when the Ballot concluded, was 
something our GitHub flow intentionally was to make easy. While that page 
stopped listing dates of adoption around Ballot 189, you can see previous 
ballot pairs (e.g. 171+164, 125+118+134+135) that did that.

 

It seems worth figuring out the challenges you're facing, since it was meant to 
be very easy to create a new version of the document for each ballot, even 
ballots that conclude closely, and to have IP reviews as such.


The administrative overhead of updating public web sites, sending additional 
emails, and the fact that we would have versions of the Guidelines that would 
be valid for a few seconds (which seems unreasonable for a public standards 
document), are some of the reasons behind aggregated final guidelines. Version 
1.6.4 aggregated 3 ballots, 1.6.7 and 1.7.1. had 2 and now 1.7.2. 


This process was discussed with Dean and Wayne back in February 2019, and we 
all considered it compliant with our Bylaws. The results of each IPR review 
period were sent to the public lists without receiving any objections or 
concerns.

Although we have documented a GitHub workflow that supports the most common 
case (one ballot, one IPR review, one Final Maintenance Guideline), it should 
not prohibit aggregated ballots to minimize administrative overhead or the 
production of Guidelines that have some reasonable validity time.

If there are strong objections to this process, we can revise it going forward.

 

I think we should understand the concerns, so we can make sure we have 
solutions that work.

 

The concerns for aggregated ballots is that, from an IP perspective, it makes 
multiple ballots share the same fate and can easily delay adoption. For 
example, imagine there are Ballots A and B. A makes a change to one section, B 
makes a change to another, and only through their combined implementation does 
a Member raise an IP concern.

 

In the serialized approach, A then B, A can be introduced to the IP review and 
not introduce any IP obligations. It can become effective. When B is introduced 
and undergoes IP review, and an exclusion is filed (on the B+A), then B is 
basically sent to the PAG to work through what to do, while A remains effective.

 

In the combined approach, A and B, when A+B trigger the IP review and result in 
the IP obligation. An exclusion is filed, and now A+B are sent to a PAG. The 
act of understanding whether it is A introducing the IP obligation or B 
introducing the IP obligation is left for the PAG to sort, with neither A nor B 
being effective until the PAG reaches recommendations.

 

This was a concern debated at length throughout our governance process, and was 
indeed one of the core motivations for our IPR policy update (which, you may 
recall, was motivated by the removal of the "any other method" introducing 
obligations on the other enumerated methods). Our IP policy was revised to try 
to make it easier to distinguish whether A or B was introducing the obligation, 
and allow modifications like A (and subsequent modifications) to continue, even 
while B was addressed within the PAG.

 

Beyond that explicit reason, the distinct versioning also helps better review 
changes and tie back to ballots. It treats Ballots as they are - logical units 
of change - rather than aggregations of change. The Forum first started with an 
aggregation-of-change approach (through submitting amendments and errata) and 
quickly confounded the ability to understand the reconciled state. The same 
issue applies to unified ballots. Given that we have CAs asserting that it's 
difficult to find changes in Ballots they explicitly voted for, after lengthy 
reviews, and with policies incorporated in at least two root programs, I'm 
incredibly sensitive to wanting to make sure CAs are set up to succeed in 
following the Requirements, by making changes discrete and digestible. 

 

So that's the context about "why" serialized was intended. I'm also totally 
sympathetic to the difficulty involved in producing ballots, especially as we 
haven't quite got automation up to speed, and so I can understand why wanting 
to avoid that work is undesirable. What I take from your reply is that there 
are several tasks that, as a consequence of our current tooling, represent 
undesirable time commitments. It's unclear if that's "5 minutes more" or "5 
hours more", and so your help in breaking down how much time it takes for the 
following would be greatly useful, as it will help prioritize what is most 
important to resolve. I suspect these can become priorities for the 
Infrastructure WG.

 

1) Merge a single Ballot into GitHub


This greatly depends on whether the ballot proposer has used the documented and 
recommended (not yet normative/required) process, using GitHub to create a 
redline. Even with GitHub, I've seen different "flavors" of redlines, for 
example with and without pull requests, making it somewhat challenging to find 
the right steps to create a cabforum/documents branch that will also create the 
artifacts (docx document) from which I can create the redline.

If we are talking about the Baseline Requirements. this process takes between 
15 minutes to 1,5 hours in the more weird cases. For the other Guidelines, it 
takes between 30 minutes to 1 hour.




2) Produce a Final Guideline and a Redlined Version

Once I have the review period redline ready, it usually takes between 30 
minutes to 1 hour to create the final documents, upload them to the wiki (the 
word versions), produce the final PDF versions and upload them to the public 
web site.




3) Draft and send the e-mail for the IP review period announcement

This usually takes between 10 and 20 minutes because I am using templates on 
Thunderbird and just replacing the links and attachments.




4) Upload the Final Guideline and Redlined Version to the website

5) Update the Website to link to these


10 to 20 minutes for both 4 and 5.




6) Draft and send the e-mail concluding the IP review period


Again 10 to 20 minutes.




 

As a number of these tasks are very automatable, figuring out what we can do so 
that it represents <30 minutes of additional work seems... a reasonable target, 
right? This only comes up when we have multiple ballots concluding within a 
short period of eachother, which although historically rare, certainly was more 
common over the summer as stuff got batched to accommodate Covid disruptions.


The most challenging and time consuming tasks come with ballots that update 
more than one Guideline, for which we don't have the same tools ready to 
produce docx versions. This requires me to do the GitHub redlines for the BRs 
and docx versions (manually) for EV Guidelines or NSRs.

Even for the BRs, I usually have to remove text after the ToC because it 
repeats information that is supposed to be in the cover page. Some of these 
minor issues need to be fixed, and I would really appreciate the help of the 
Infrastructure Subcommittee.

Would your concerns be addressed if we had a separate/distinct IPR review for 
each ballot and once each IPR review is cleared with no essential claims filed, 
produce an aggregate document, or you still prefer separate Final documents 
with distinct versioning to be created? What do others think?

Best regards,
Dimitris.
