<abstract |
This paper presents new evidence that elephant populations
significantly affect regional climate patterns through their
role in shaping vegetation and carbon storage.
>

Unstructured abstract (the default). Single paragraph of summary prose.

Compiles to eHTML <affiliation>.

<author>
  <name | Jane Goodall>
  <affiliation | Anthropic>
</author>

Simple author affiliation. The affiliation sits as a sub-element of <author>, parallel to other rich-author-metadata elements (<orcid>, <email>).

Compiles to eHTML <article-subtitle>.

Compiles to eHTML <article-title>.

Compiles to eHTML <author>.

Backward-compatible casual form (carried forward from before the structured-interface reconciliation). The pipe content sits as text content of <author>; it is NOT lifted to a <name> child — authors who want the structured shape use the kwarg form below or the child-tag form. JATS export reads the name string either way.

Compiles to eHTML <book-part-title>.

Compiles to eHTML <book-subtitle>.

Compiles to eHTML <book-title>.

Compiles to eHTML <config>.

The authoring form for <config> is kwargs. Settings are read at the discovery pass into the configuration registry; the element itself produces no body output (it renders as an empty <config>).

Compiles to eHTML <date>.

A bare <date> is UNTYPED (no data-date-type) — an authoring date is “when you wrote it” (like the date on a letter), not a publication date (cf. Quarto/Pandoc/Bookdown preamble date slots). Use an explicit type= (e.g. <date type=publication | …>) for a typed date. (#325)

Compiles to eHTML <editor>.

Casual form — the pipe content is the editor’s name (text content, not lifted to a <name> child), mirroring <author | …>.

Compiles to eHTML <email>.

<author>
  <name | Jane Goodall>
  <email | jane@example.org>
</author>

Author contact email. Common in journal article metadata for the corresponding author (see also the +corresponding boolean kwarg on <author>).

Compiles to eHTML <keywords>.

<meta>
  <keywords | elephants, conservation, climate, carbon storage>
</meta>

Comma-separated keyword list — the simpler and more common authoring form. The exporter splits on commas when emitting JATS.

Compiles to eHTML <lang>.

<meta>
  <lang | en-US>
</meta>

BCP 47 language tag. The eHTML form preserves the value as a child element of <meta>; downstream consumers (the JATS exporter, the render-mode lowering) project it where each format expects.

Compiles to eHTML <license>.

<meta>
  <license href="https://creativecommons.org/licenses/by/4.0/" | CC BY 4.0>
</meta>

License name with canonical URL.

Compiles to eHTML <meta>.

<meta type=article>
  <title | The Effect of Elephants on Climate>
  <author | Jane Goodall>
  <date | 2024-03-15>
</meta>

<section | Introduction>
The paper begins.

*Author writes <meta type=article> at the top with no <article> wrapper. The structural plugin reads type=article and generates:

• the <article> container
• <article-front> wrapping the original <meta>
• <article-body> wrapping the section content <title> is promoted to <article-title> as the first child of <meta>. <meta> itself survives in the output, inside <article-front>.*

Compiles to eHTML <name>.

<author>
  <name | Jane Goodall>
</author>

The common case. Pipe content becomes the name string.

Compiles to eHTML <orcid>.

<author>
  <name | Jane Goodall>
  <orcid | 0000-0002-1825-0097>
</author>

Bare 16-digit ORCID — the canonical form.

Compiles to eHTML <publication-date>.

<meta>
  <publication-date | 2024-03-15>
</meta>

ISO 8601 publication date — the preferred form.

Compiles to eHTML <subject>.

<meta>
  <subject | Ecology of large mammals>
</meta>

Free-form subject. Common for general-interest documents.

Compiles to eHTML <subtitle>.

<meta>
  <title | The Effect of Elephants on Climate>
  <subtitle | A Multi-Year Field Study in Tanzania>
</meta>

Compiles to eHTML <title>.

<meta>
  <title | The Effect of Elephants on Climate>
</meta>

Inside <article>, <title> in <meta> becomes <article-title>.

Compiles to eHTML <version>.

<meta>
  <version | 1.0.0>
</meta>

Semantic version. Other formats are equally valid as a free-form string.
