A syndication feed is an Atom 1.0 document
(RFC 4287). The default
namespace is http://www.w3.org/2005/Atom. The structural model is
captured by the SyndicationFeed
logical model.
xmlns="http://www.w3.org/2005/Atom"
xmlns:ncts="http://ns.electronichealth.net.au/ncts/syndication/asf/extensions/1.0.0"
xmlns:sct="http://snomed.info/syndication/sct-extension/1.0.0"
The sct: namespace is only required if any entry uses SNOMED CT
extension elements. The onto: namespace
(http://ontoserver.csiro.au/syndication/) is only required if any
entry uses the per-entry permission or per-link validation
extensions.
| Element | Card | Meaning / Constraint |
|---|---|---|
<id> |
1..1 | Stable, globally-unique identifier for the feed. Conventionally urn:uuid:<uuid>. MUST NOT change across re-publications of the same logical feed (RFC 4287 §4.2.6). |
<title> |
1..1 | Human-readable feed name. |
<subtitle> |
0..1 | Human-readable description. |
<updated> |
1..1 | RFC 3339 timestamp. SHOULD equal the maximum <updated> of any entry currently in the feed. |
<generator> |
0..1 | Identifies the publishing software. |
<link rel="self"> |
0..1 | Canonical URL of the feed. type is application/atom+xml. |
<ncts:atomSyndicationFormatProfile> |
0..1 | ASF profile URI. MUST be present whenever any NCTS ASF extension element is used in the feed. Current value: http://ns.electronichealth.net.au/ncts/syndication/asf/profile/1.0.0. |
<entry> |
0..* | Zero or more entries. Order is publisher-defined; consumers MUST NOT rely on order to determine recency — use entry-level <updated>. |
The format does not define a pagination scheme — a feed is a single
document. Publishers handling very large catalogues typically split
content across multiple feeds and use <link rel="related"> to
reference them; this is out of scope for this specification.
The MIME type for an Atom feed document is application/atom+xml.
