Cool.

I’d be inclined to use DocBook markup for the specific properties you’re
interested in:

  <article audience="…">
    <info>
      <keywordset>
        <keyword>…</keyword>
      </keywordset>
      <!-- or subjectset if you have a controlled vocabulary -->
      <abstract>
        <para>about…</para>
      </abstract>
    </info>
    …

I imagine you’ll want to run some sort of extraction process to get
metadata out of your documents (to put in a linked data store, for
example), and there’s no reason not to map from DocBook metadata to
properties.

But that doesn’t answer your general question.

Yes, it does.

DocBook 5.2 introduces such an element which can either contain content
or be empty:

  https://tdg.docbook.org/tdg/5.2/meta.content.html
  https://tdg.docbook.org/tdg/5.2/meta.empty.html

It’s perhaps geared a little too strongly towards the HTML style of meta
element. It could probably be relaxed a little bit, so that name was
optional for example, to make it fit this use case a little better.

                                        Be seeing you,
                                          norm
