A block-level event in the text-level vocabulary — what a format adapter emits. Headings arrive flat; the section tree is derived here, once, for every adapter.

Variants

Heading

A flat heading: level is the source level (h2 → 2, a LaTeX \section → its depth), lemma its text.

Fields

level: u8

lemma: String

Paragraph

A plain paragraph — the implicit, lemma-less block.

Fields

text: String

Text

Inline content belonging directly to the open container (a list item’s own text, a bare-text blockquote). With no open container it is read as a paragraph.

Fields

text: String

Open

Open a nesting container. Items take their unordered- / ordered- flavor (and taxis) from the enclosing list.

Fields

kind: Container

lemma: Option<String>

Close

Close the innermost open container, optionally with its hypograph (footer or attribution).

Fields

hypograph: Option<String>

Verbatim

A verbatim block — code or other preformatted lines, kept as authored.

Fields

lang: Option<String>

text: String

NoteRef

An in-text note callout (the deixis, ruling #35): onym names the body it cites within its family. Emitted after the flow block it sits in; it becomes that block’s child, in order, and the block’s own text stays clean of markers. family: None means the source declares none (an HTML noteref): the callout takes its resolved body’s family, and a dangling one defaults to footnote.

Fields

onym: String

family: Option<NoteFamily>

margin: bool

The declared spelling placed this pair in the margin (a Tufte-style sidenote): surfaced as ::::form = "margin" on both ends — the family stays footnote, placement is presentation.

IndexMark

An index mark (ruling #36): an invisible anchor declaring this place concerns term. The back-of-book index is a query over these, never a stored structure.

Fields

term: String

Verse

A verse block (ruling #37 — litogramma’s stichoi model): strophes of lines, denormalized like Block::Table. Lines arrive flattened by the adapter and are kept as authored; the stichos ::taxis numbers lines 1-based, CONTINUOUSLY across strophes — the citation coordinate.

Fields

lemma: Option<String>

strophes: Vec<Vec<String>>

hypograph: Option<String>

Table

A table, denormalized here into nested lists (rows = ordered items with the <row> trait, cells = unordered items with the <cell> trait and the column name as ::lemma). Header detection is the adapter’s job; the lowering rule lives here. A cell’s own label (a row’s th) wins over the positional headers entry.

Fields

lemma: Option<String>

headers: Option<Vec<String>>

rows: Vec<Vec<Cell>>
