I've briefly looked at Richard's html example and AsciiDoc source.

I'm impressed by the readability of the AsciiDoc source, something which is lacking in DocBook. This would make it much more practical for people to edit it without special software. We badly need that capability. And in most respects the newly generated version of the document looks good!

At first glance I noticed two features which seem to be missing in the html example. I'm not sure whether they are essential features, and I don't know whether they can be supported with AsciiDoc. But if moving to AsciiDoc means dropping them, I think we need a community consensus in favor of that.

1. Most important, it has long been policy that all changes to the CF Conventions document are provisional and are to be marked as such. The example html document has no such markings. In the existing system, changes are marked with a highlighting system which I find annoying to read and some trouble to implement. So far, no change has been promoted beyond provisional status. Do we want to keep the policy on provisional changes? If so, how do we want to mark the changes?

2. Some semi-graphical features of the standard document, notably the color-coded tables of chapter 9, are not reproduced in the AsciiDoc-based html page which I see. But in the source code I can see an attempt to reproduce them. If this is just a small bug somewhere, then we can fix it. If reproducing such features requires major work, or is impossible with AsciiDoc, we need to decide whether they are important to us.

Jonathan,

Thanks for the rapid feedback.


Not all the formatting is quite right, as I am sure you know e.g. in the 
examples, and especially in Appendix D.
Quite so. If this idea has wings then we'll need to record all these 
deficiencies.


I see that the doc doesn't say which version it is.
It does at the top, but it's quite small. This is just the default rendering 
style though so could be changed. I'm guessing normal books don't care about 
the version that much!


I expect you're still working on it.
That remains to be seen... but I suspect so. ;-)


In the "official" version there is markup for changed text, as you know. Is 
there a way to do this?
There is, but my current pipeline explicitly removes such things to show the document in 
its "finalised" form.


Jeff Painter's opinion would be valuable.
Absolutely!


My main concern is review.
I see no reason why the current trac process couldn't remain for now. Once the 
changes have been finalised on trac then someone (probably either the 
originator or a maintainer) could submit those changes via GitHub, with 
reference to the trac original.

However, there is the potential for even greater benefit if the trac tickets 
themselves are moved to GitHub. This would allow inline reviewing of proposed 
changes.

Either way, one or more people (e.g. Jeff) would need to be given merge rights 
to the GitHub repo. (To be clear, I am not trying to get myself on that list!)


Regards,
Richard

Dear Richard

Thank you very much for trying this out. It looks really good. Not all the 
formatting is quite right, as I am sure you know e.g. in the examples, and 
especially in Appendix D. I see that the doc doesn't say which version it is.
I expect you're still working on it.

If this is easier than using docbook to generate the html and pdf then it 
sounds attractive. I have never used docbook. Jeff Painter's opinion would be 
valuable.

In the "official" version there is markup for changed text, as you know. Is 
there a way to do this? In fact there is a question, which we've discussed before, about 
whether we should alter the rules for updates so we don't have to mark so many changes as 
provisional. At the moment, all changes ever since the first version are still shown as 
provisional because we have no rule for accepting them as permanent. If we change the 
rules, however, we might still want to show changes for a while, so a way to do it would 
be helpful.

My main concern is review. CF changes are agreed in trac tickets, and the trac 
ticket should say exactly what text change is to be made. Once we reach that 
stage, we then have to decide who is going to make that change in the document 
source, when they are going to make it, and who will check that it has been 
done correctly. Up to now, one person (currently Jeff) has made all the 
changes, at once, and others have informally reviewed the html, for each 
version. These are governance issues, rather than software issues.

Best wishes

Jonathan

Dear all,

Summary for the time-pressed reader:
- Some of us would like to simplify the workflow for editing the CF conventions.
- I've made a work-in-progress demo here: 
http://cf-metadata.github.io/cf-conventions.html.
- The demo is automatically built from AsciiDoc sources here:
https://github.com/cf-metadata/cf-conventions-asciidoc
- Feedback welcome! What's the appetite for exploring further?

I've recently delved back into the options for simplifying and automating the 
workflow for modifying the CF conventions document. This is in the light of 
some useful discussion early last year, and a friendly nudge from Rich Signell 
(thanks Rich!).

In general, this has been an encouraging exploration. Fortunately we are not at the 
technological vanguard of the publishing world - others with greater resources (e.g. 
O'Reilly) have already paved the way. As a result I believe we can achieve a very 
workable solution based around the AsciiDoc 
format<http://asciidoctor.org/docs/what-is-asciidoc/>.

There are three main problems I've been looking at:

1.       How to get from the current DocBook sources to AsciiDoc?

2.       How to make the authoring/reviewing process easier?

3.       How to convert AsciiDoc to HTML and PDF?

To get from DocBook to AsciiDoc I have extended an existing 
solution<https://github.com/rhattersley/docbook2asciidoc> from O'Reilly. They 
use the AsciiDoc format in their Atlas publishing platform so they have already done 
most of the hard work. Where possible I'd like to get my extensions merged into their 
original.

The authoring/reviewing process relies on GitHub pull requests and their 
built-in support for rendering AsciiDoc. This provides a good preview of the 
document (although some features of the final HTML output are not rendered), 
and an inline reviewing system. (NB. I've split the document into multiple 
files, but that is not essential.) Once a change has been accepted the 
corresponding HTML (and eventually PDF) is automatically rebuilt and pushed to 
the demo website.

To get from AsciiDoc to HTML/PDF I have used the excellent 
asciidoctor<http://asciidoctor.org/> software for HTML and a sister project for 
PDF. The HTML support is excellent but the PDF solution is less mature (there is an 
alternative which might do better). That said, both projects are under active 
support/development and are open to contribution.

Questions, feedback, encouragement, offers of assistance and/or beer
... they're all welcome! ;-)
