Crate openehr_adl 

openEHR ADL 2.4.0 — the hand-written ADL2 engine: ADL2/cADL/ODIN source parser, the AOM2 validation catalogue, specialisation flattening, OPT2 generation, and ADL 1.4→2 conversion, built over the generated openehr_am::v2_4 object model.

Spec oracle: docs/specs/openehr/AM/docs/{ADL2,AOM2,OPT2}/ (+ the ODIN spec at docs/specs/openehr/LANG/docs/odin/). The normative ANTLR4 grammars are vendored under vendor/grammar/ (version-scoped by AM generation: v1_4/, v2_4/) as reference input for the hand-written logos/chumsky implementation — no ANTLR runtime.

Components: the outer artefact parser (source), the shared typed error catalogue, and the cADL definition-section parser (parse) that builds the openehr_am::v2_4::aom2 constraint model. The substrate under them is aom (field accessors, constructors, interval arithmetic), artefact (artefact views + the parent/supplier repository), hrid (the archetype-id grammar) and odin (the ODIN reading bridge). Above them: codes/paths, validate, flatten + opt, the ADL2 serializer print, and adl14 (1.4→2 conversion — our own design/extension, no openEHR spec).

The crate has NO lexer of its own: the cADL token stream is the shared workspace lexical layer under its ADL reading (openehr_lang::v1_1::lexer::lex_adl), and ODIN sections go through the openehr_lang::v1_1::odin reader. The rules body and the slot include/exclude assertions are BEL expression trees (rules) whose string form is rendered back from the tree (print::assertion_text), never parsed out of it.

Modules

adl14

ADL 1.4 → ADL 2 conversion (the adl14 1.4→2 upgrade pipeline).

aom

The shared AOM2 substrate: one home for reading, building, and doing interval arithmetic over the generated openehr_am::v2_4::aom2 constraint model.

artefact

Artefact-level views and the parent/supplier repository — the crate-wide access layer over an assembled openehr_am::v2_4::aom2 Archetype.

assemble

Assembles a parsed ADL artefact into the generated AOM2 object model.

codes

Specialisation-code utilities over the AOM2 ADL_CODE_DEFINITIONS class.

error

Typed ADL2 syntax errors.

flatten

Specialisation flattening — overlay a differential child archetype onto its flat parent to produce the flat form.

hrid

The archetype human-readable-identifier (HRID) grammar — the single home for reading, writing, and keying an ARCHETYPE_HRID.

meta

Parsed-artefact identity summary.

odin

The ODIN bridge — one home for reading an openehr_lang::v1_1::odin value tree into AOM/BASE types, plus the master03 lexical decoding both ODIN and cADL share.

opt

OPT2 — operational-template generation (raw + profiled).

parse

The cADL definition-section parser.

paths

Archetype path utilities over the parsed AOM2 constraint model.

print

The ADL2 serializer: render an assembled openehr_am::v2_4::aom2 Archetype back to ADL2 source text.

rules

The ADL2 rules section + structured slot-assertion parser.

source

The outer ADL artefact parser: sections, kind, meta, spans.

validate

The AOM2 validation engine: orchestration over a catalogue of topic modules.

Constants

SPEC_VERSION

The openEHR specification version this crate implements.
