Authoring

openEHR Specification Document Authoring

This skill covers creating and editing openEHR specification documents — the AsciiDoc sources that live in specifications-XX repositories (RM, AM, BASE, LANG, PROC, SM, QUERY, CNF, TERM, ITS-*).

> Note: specifications-ITS-REST is an exception — it uses OpenAPI YAML with embedded Markdown > rather than the standard AsciiDoc approach. See the "ITS-REST Exception" section below.

Repository Layout

Each specification component lives in its own repo: specifications-XX (e.g., specifications-RM). The shared infrastructure repo specifications-AA_GLOBAL provides boilerplate, styles, references, and publishing scripts used by all components.

specifications-XX/
├── manifest.json              # Component metadata, specs, releases, Jira links
├── docs/
│   ├── index.adoc             # Component index page
│   ├── /             # One directory per specification
│   │   ├── master.adoc        # Main entry point
│   │   ├── manifest_vars.adoc # Per-spec variables
│   │   ├── master00-amendment_record.adoc
│   │   ├── master01-preface.adoc
│   │   ├── master02-*.adoc ... masterNN-*.adoc
│   │   ├── diagrams/          # SVG/PNG diagrams
│   │   └── images/            # Other images
│   ├── UML/                   # BMM-generated class docs + diagrams (do NOT hand-edit; see class-generation skill)
│   └── common/                # Shared content within component

The specifications-AA_GLOBAL repo (always a sibling) provides:

specifications-AA_GLOBAL/
├── docs/boilerplate/          # Shared AsciiDoc includes
│   ├── global_vars.adoc       # Global Asciidoctor attributes
│   ├── book_style_settings.adoc
│   ├── basic_style_settings.adoc
│   ├── full_front_block.adoc  # Full front matter (with block diagram)
│   ├── short_front_block.adoc # Short front matter (without block diagram)
│   ├── doc_id_block.adoc      # Release/status/revision table
│   └── licence_block.adoc     # Copyright and licence table
├── docs/references/
│   └── reference_definitions.adoc  # All cross-spec and external URLs
├── resources/css/             # Stylesheets
├── resources/logos/           # openEHR logos
└── bin/
    ├── spec_publish.sh        # Main publishing script
    └── do_spec_publish.sh     # Wrapper

The {ref_dir} Asciidoctor attribute resolves to the AA_GLOBAL repo root relative to the consuming spec document.

Creating a New Specification Document

Step 1: Create the spec directory

Under specifications-XX/docs/, create a directory matching the spec id from manifest.json.

Step 2: Create manifest_vars.adoc

This file defines per-document Asciidoctor attributes used by the boilerplate:

:spec_title: EHR Information Model
:copyright_year: 2003
:spec_status: STABLE
:keywords: EHR, EMR, reference model, openehr
:description: openEHR EHR Information Model specification

Fields:

• :spec_title: — The document title, displayed after the openEHR logo
• :copyright_year: — Year of first publication (used in licence block)
• :spec_status: — One of: DEVELOPMENT, TRIAL, STABLE, SUPERSEDED, OBSOLETE, RETIRED
• :keywords: — Comma-separated keywords for the HTML meta tag
• :description: — One-line description for the HTML meta tag

Step 3: Create master.adoc

The master file follows a strict structure. Here is the canonical template:

//
// ============================================ Asciidoc HEADER =============================================
//
include::{ref_dir}/docs/boilerplate/book_style_settings.adoc[]
include::manifest_vars.adoc[]
include::{ref_dir}/docs/boilerplate/global_vars.adoc[]

//
// ============================================ Asciidoc PREAMBLE =============================================
//

image::{openehr_logo}["openEHR logo",align="center"]

= {spec_title}

include::{ref_dir}/docs/boilerplate/full_front_block.adoc[]
include::{ref_dir}/docs/references/reference_definitions.adoc[]

//
// ============================================= Asciidoc BODY ===============================================
//

//
// --------------------------------------------- Preface -----------------------------------------------
//

:sectnums:

ifdef::package_qualifiers[]
:pkg: org.openehr...
endif::[]

include::master01-preface.adoc[leveloffset=+1]
include::master02-overview.adoc[leveloffset=+1]
// ... additional chapters ...

//
// --------------------------------------------- Amendment Record -----------------------------------------------
//
:sectnums!:
include::master00-amendment_record.adoc[leveloffset=+1]

//
// --------------------------------------------- REFERENCES -----------------------------------------------
//
:sectnums!:
== References

bibliography::[]

Include order in the header matters:

1. book_style_settings.adoc — sets doctype, syntax highlighter, TOC
2. manifest_vars.adoc — local spec variables
3. global_vars.adoc — global openEHR attributes (depends on nothing above)

Front block choice:

• Use full_front_block.adoc for primary specifications (includes block diagram)
• Use short_front_block.adoc for secondary/overview documents (no block diagram)

Step 4: Create master00-amendment_record.adoc

= Amendment Record

[cols="1a,6,2,2a", options="header"]
|===
|Issue|Details|Raiser|Completed

|[[latest_issue]]0.1.0
|Initial writing.
|
|[[latest_issue_date]]

|===

The [[latest_issue]] and [[latest_issue_date]] anchors are required — the doc_id_block.adoc references them to display revision and date in the front matter table.

Amendment record entries reference Jira tickets using {spec_tickets}/SPECXX-NNN[SPECXX-NNN^] syntax. Release boundaries are marked with a full-width header row:

4+^h|*RM Release 1.1.0*

Step 5: Create chapter files

Name chapters sequentially: master01-preface.adoc, master02-overview.adoc, etc.

The preface (master01-preface.adoc) typically contains:

• Purpose of the specification
• Related documents
• Conformance/status notes
• Conventions used

Step 6: Update manifest.json

Add the new specification entry to the specifications array. See references/manifest-spec-entry.md for the full field reference.

Step 7: Publish locally

# From the parent directory containing all specifications-XX repos:
./specifications-AA_GLOBAL/bin/spec_publish.sh -f -v XX
# Or via Docker:
docker run -u $(id -u):$(id -g) -v "$(pwd):/documents/" openehr/asciidoctor development XX

Editing Existing Specifications

Conventions

• Chapter files: Edit masterNN-*.adoc files directly. Never edit files under docs/UML/ — those are generated from the component's BMM schema by bmm-publisher (see the class-generation skill); change the BMM and regenerate.
• Cross-references within spec: Use > or >.
• Cross-references to other specs: Use the URL attributes from reference_definitions.adoc:

``asciidoc {openehr_rm_common}[Common IM^] {openehr_rm_data_types}#dv_quantity[DV_QUANTITY^] ``

• Cross-references to classes: Use {classes_url_root} for linking to the class index.
• Jira ticket references: {spec_tickets}/SPECRM-87[SPECRM-87^]
• External references: Check reference_definitions.adoc first — it has hundreds of pre-defined URLs for HL7, W3C, ISO, IETF, Wikipedia, SNOMED, etc.

Global Variables

All release version attributes follow the pattern :{component_id}_release: and default to latest. These are defined in global_vars.adoc:

:rm_release: latest
:am_release: latest
:base_release: latest
...

When publishing a named release, the publisher overrides these via -a rm_release=Release-1.0.4.

URL Patterns in reference_definitions.adoc

References follow a consistent naming convention:

:openehr_{component}_{spec}: {openehr_{component}_releases}/{spec}.html
:openehr_{component}_latest_{spec}: {openehr_{component}_latest}/{spec}.html
:openehr_{component}_development_{spec}: {openehr_{component}_development}/{spec}.html

When adding new references, follow this pattern exactly.

Amendment Record Updates

When editing a specification, always update the amendment record:

1. Add a new entry at the top of the table (most recent first)
2. Reference the relevant CR/PR Jira tickets
3. Update [[latest_issue]] version and [[latest_issue_date]] date on the new top entry
4. For non-release changes, increment the patch version

Diagrams

• Place SVG diagrams in /diagrams/
• Reference as: image::{diagrams_uri}/[...]
• UML class and package diagrams are generated from the component's BMM schema by bmm-publisher (which renders them to SVG via PlantUML). This replaces the historical MagicDraw .mdzip extraction. See the class-generation skill to regenerate them.

ITS-REST Exception

The specifications-ITS-REST component uses a different authoring approach:

• REST API definitions are specified using OpenAPI YAML schemas, not AsciiDoc
• Some documentation within ITS-REST is written in Markdown (embedded in the OpenAPI schema), not AsciiDoc
• Not all text documents in ITS-REST follow the standard AsciiDoc conventions described above
• The OpenAPI YAML files define REST API endpoints, request/response bodies, and include inline Markdown descriptions
