Hi,

First, as discussed a while back we want to move DESCRIPTION and KEYWORDS
out of ox.el as they are specific to certain backends.  The first patch
does this.

Second, I want to add support for printing keywords.  This patch is still
rough (i.e. no need commenting), but before proceeding I want to discuss
some things.  The goal is to allow cool stuff like:

   #+begin_abstract
     Read my paper, please...
     #+keywords: org, markup
   #+end_abstract

And eventually:

   #+tile: my fancy blog
   #+keywords: org, markup

Where 'org' and 'markup' would magically become links to indexes (like on
them fancy blogs on the interwebs).  I'm still not sure how to do the
latter (see TODO comment in patch).

So, I'm in a dilemma now.  On the one hand, ox should probably not include
too much cruft that is specific to certain backends.  OTOH, stuff like the
repetition of org-BACKEND-with-keywords and org-BACKEND-keywords-prefix is
a bit annoying (cf. patch).

Another idea I want to discuss.  I use "prefix" to designate what is
printed before the :.  By default the translated value of "Keywords".
Would it make sense to make this configurable in the file, e.g. as

      #+KEYWORDS: [my prefix: ] key0, key1, ....

Thanks.

You can remove the keywords from "ox-org.el" and "ox-ascii.el", as they
do not use them. You need to update (info "(org)Publishing options")
accordingly, too.

I fail to see how it is "cool". KEYWORDS are meant to add contents to
meta-data, i.e., an area you cannot reach easily with regular Org
syntax. As a consequence, KEYWORDS doesn't mean much for back-ends not
supporting such meta-data.

If KEYWORDS are meant to be inserted in the buffer, then write them
using regular syntax, e.g.,

  #+begin_abstract
  Read my paper, please...

  Keywords-in-my-language: [[http://link-to-tag-cloud][org]]
  #+end_abstract

We don't need a convoluted markup for that, let's keep it simple.

But then you'd have to repeat data.  E.g.

#+KEYWORDS: my keywords for meta-data that should also be printed.
my keywords for meta-data that should also be printed.

This seems error prone and undesirable IMO.

Except that this is not a real repetition. As you mentioned, in the
latter case, you want to throw in links and probably other markup, which
make no sense in plain meta-data.

IMO, this is over-engineering.

Keywords are akin to small headings to identify the contents of a
document.  I see no reason to restrict this to the reader of the
electronic version of a document.

I disagree, but extrapolating this will go nowhere.

What are you talking about? I don't want to restrict anything: AFAIU,
the feature you propose already exists in another form.

Again, your proposal is to have KEYWORDS mix two different things, i.e.,
set meta-data in document's header and set contents in the document. My
opinion is that for a given topic, you probably don't always want the
same contents, e.g., in "\\hyperref{pdfkeywords={...}}" and at the
beginning of the document, if only for the limitations on the syntax
allowed in the former.

Therefore, we may consider keeping the two features separated.

Do you think that you /always/ want "pdfkeywords" to hold exactly the
same contents as what you could put in your document? Do you think that
a user who wants to fill pdfkeywords will always want to also add these
contents in the body of the document?

Which is why the patch provided a switch in #+OPTIONS.

IIUC, it contradicts your initial post where you wanted, at some later
time, to add bells and whistles to keywords displayed in the output
(e.g., turning them into links).

I'm not very keen on the idea of KEYWORD doing two different things. If
that's not the case, I'm fine with it.

The switch is all or nothing. Again, you're talking about two different
features : keywords in meta-data and keywords in data.

I have now reviewed this section twice, and I have no clue what you want
me to change there.  There's no :with-keywords or :with-description.  At
least SUBTITLE for ox-texinfo in not documented here.

I don't know either. I was sure that :keywords and :description were
here, but, oddly, it isn't the case. That's a documentation bug as long
as these keywords are in "ox.el".

> At least SUBTITLE for ox-texinfo in not documented here.

That's also a documentation bug. Note that it should probably
be :texinfo-subtitle (and :texinfo-subauthor).

By this logic we'd have to add *every* "global" keyword, no?  Does it make
sense?

Unless we add a #+SUBTITLE...

So should I go ahead a kill KEYWORD and DESCRIPTION in ox?

Every global (as in "ox.el") keyword should be documented there, indeed.

It depends. Adding a prefix allows to specify a subtitle per back-end
when publishing through multiple back-ends. Not a big deal, tho.

> So should I go ahead a kill KEYWORD and DESCRIPTION in ox?

IIUC, this is what we agreed on in the related thread.

OK.

Marc: you expressed a desire to fix some bugs.  I don't know if you like
documentation bugs, or whether you are more into code bugs.  If you like
documentation, would that be something you'd want to do?

It would make it hard to set *a* subtitle through publishing.  As a user I
don't care about the implementation detail and I would prefer :subtitle
(should I ever need to specify a subtitle via publishing).
