Terminology Syndication Feed IG

Published: https://fhir.github.io/fhir-syndication-ig/

FHIR Implementation Guide specifying the Atom-based terminology syndication feed format. Documents the feed and entry shape, field semantics, cross-field constraints, the controlled vocabularies used in <category>, and the three extension namespaces:

• NCTS ASF — http://ns.electronichealth.net.au/ncts/syndication/asf/extensions/1.0.0
• SNOMED CT — http://snomed.info/syndication/sct-extension/1.0.0
• Ontoserver — http://ontoserver.csiro.au/syndication/

Canonical: https://ontoserver.csiro.au/syndication. Package id: aehrc.syndication.

This is a specification of the wire format. It does not document any particular publisher's or consumer's behaviour.

Build

Requires SUSHI v3+ and (for the full IG) Java 17+ and the HL7 FHIR IG Publisher.

# FSH only — fast, no IG Publisher
sushi .

# Full IG build
./_updatePublisher.sh   # one-off: fetch publisher.jar into input-cache/
./_genonce.sh           # SUSHI + IG Publisher → output/

Windows: _updatePublisher.bat and _genonce.bat.

Continuous build

.github/workflows/build.yml runs the full IG Publisher build on every push to main and on every PR. The main-branch build is deployed to GitHub Pages (output/ → site root). Per-run artefacts are kept for 14 days.

To enable Pages deployment: in repo settings → Pages, set source to "GitHub Actions". The first push to main will populate the site.

HL7 auto-builder

To have the HL7 auto-builder at https://build.fhir.org/ig/ rebuild this IG on every push:

1. Push the repo to a public GitHub repository.
2. Open a PR against https://github.com/FHIR/ig-registry adding this repo to fhir-ig-list.json.

The HL7 auto-builder reads ig.ini and the standard _genonce.sh / _updatePublisher.sh scripts that this repo already provides.
