Ocean Health Systems

Ocean Health Systems (legally Ocean Informatics Pty Ltd, founded 1998, with offices in Bundall QLD, Chatswood NSW and London) is the Australian clinical-informatics company whose founders commercialised the first openEHR clinical data repository and built Clinical Knowledge Manager (CKM) — the repository and collaborative governance environment in which openEHR archetypes, templates, terminology subsets and release sets are authored, peer reviewed, semantically versioned, approved and published, with terminology binding to SNOMED CT and LOINC and mappings out to FHIR and OMOP. CKM runs the international openEHR community instance as well as national and vendor deployments, and ships a documented Swagger 2.0 REST API (48 operations) for discovering models and pulling their ADL, XML, OET and Operational Template representations. Ocean also builds Multiprac Immunize and Multiprac Surveillance for immunisation and infection prevention, and publishes the free Archetype Editor and Template Designer authoring tools.

Ocean Health Systems publishes 9 API contracts indexed on the APIs.io network, including Archetypes API, Change Requests API, Projects API, and 6 more. Tagged areas include Health, Healthcare, Electronic Health Records, openEHR, and Clinical Data.

The Ocean Health Systems catalog on APIs.io includes 1 Spectral governance ruleset.

Ocean Health Systems’ developer surface includes documentation, API reference, support, engineering blog, authentication, changelog, and 18 more developer resources.

Kin Score

Kin Score Kin Score How this is scored →
scored 2026-11-06 · rubric v0.27.0
Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.
Create-or-Update Ergonomics applies to this provider. This API accepts writes, so it carries 10 points of the composite. It is scored from the published contracts themselves: whether a caller can create-or-update in one call, whether the write accepts a key the caller already holds, and whether the response says which branch ran. Without that, every write needs a search-and-branch in front of it, and the first time that check is skipped a duplicate record is created. Scored against the observed mean rather than raw — a provider at the catalog average is unchanged by this facet, not penalised by it.
The six quality facets above are damped to 75 points between them, because the conditional facet above carries the other 25. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 75% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.

Agent readiness — checks not met, largest first (exact, from this profile):
  • MCP Server +12 pts — deployment.mode + probe verdict on the mcp/ manifest, not the pointer; an unprobed slug falls back to authorship
  • Agentic Access Contract +10 pts — agentic_access artifact present (x-agentic-access), graded by author
  • Idempotency +9 pts — OpenAPI mutating operations declare an idempotency key — a header, a request-body property, or a named de-duplication token whose own description says so (verified); else common[].type matches /idempoten/i (documented)
  • A2A Agent Card +8 pts — a2a/-a2a.yml manifest, graded on conformance.grade against A2A 1.0.0
  • Registration Without a Human +6 pts — a `registration_endpoint` in the served RFC 8414 / OIDC discovery document
  • Delegated User Identity +6 pts — a served discovery document listing authorization_code in grant_types_supported (served), else an oauth2 authorizationCode flow or openIdConnect declared in an OpenAPI (documented)
7 more unmet checks in the Agent Readiness table above.
Kin Score — facets with the most composite points still available (weight × headroom):
Each check links to what satisfies it. Publish the artifact, or tell us where it already lives, and the score moves on the next scoring run.
Improve this rating by publishing the missing artifacts — every area above can be raised, and the full rubric is at apis.io/rating/. Every facet and dimension name above is a link: it opens that measurement's own page — what it means, the exact checks that feed it, how the whole catalog distributes on it, and the providers at the top of it. This rating is computed from the provider profile at artifacts.apis.io/ocean-health-systems/apis.yml: open an issue on github.com/api-evangelist/ocean-health-systems to ask a question or point us at an artifact you publish.

Standards implemented 2

Standards this provider implements or carries. De facto ones are profiled and measured by the API Commons; formal ones come from the standards directory and are linked by the provider's own tags. The evidence column says how each claim was established — not that it was made.

tagged — the provider's own APIs.json carries the standard as a tag; implementation not verified
measured — observed by APIs.io (published)
