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 1 API on the APIs.io network: CKM REST API. Tagged areas include Health, Healthcare, Electronic Health Records, openEHR, and Clinical Data.
Ocean Health Systems’ developer surface includes documentation, API reference, support, engineering blog, authentication, changelog, and 18 more developer resources.
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.
The six quality facets above are damped to 85 points between them,
because the conditional facet above carries the other
15. That is why each facet's contribution is shown against a damped
maximum: raising a quality facet moves the composite by 85% of its nominal
weight, not 100%. The full arithmetic is at apis.io/rating/.

- name: CKM REST API
description: REST API for the Clinical Knowledge Manager — 48 operations across 39 paths covering archetypes (list, search,
ADL/XML/mindmap retrieval, specialisation parent, status by asset version, MD5 hash, import, trunk update, delete), templates
(list, search, OET/OPT retrieval, file-set URL, required archetypes, embedded templates, validation report, status read
and update, import, trunk update, delete), the archetype/template union "resources" view with the instance publisher namespace,
projects and subdomains, change requests and resource proposals, and user and session management. Authentication is HTTP
Basic or a JSESSIONID session header; public projects on a public instance read anonymously.
humanURL: https://ckm.openehr.org/ckm/rest-doc/
baseURL: https://ckm.openehr.org/ckm/rest/v1
x-base-url-note: The published Swagger 2.0 contract declares basePath /ckm/rest/v1 and NO host, because CKM is licensed
software deployed per organisation — the host is whichever CKM instance the caller has access to. The baseURL recorded
here is the public reference deployment, openEHR International's instance of Ocean's CKM. The identical contract is served
at https://arketyper.no/ckm/rest/v1, which confirms the contract belongs to Ocean's software rather than to any single
host.
x-ownership: 'Ownership verified 2026-09-02 against the spec''s own self-description, not its fetch URL: info.title "CKM
REST API", info.contact.name "CKM Support", info.contact.email ckm@oceaninformatics.com, and info.contact.url the Ocean
service desk at https://oceanehr.atlassian.net/servicedesk/customer/portal/15. oceaninformatics.com and oceanehr.com both
301 to oceanhealthsystems.com, so the contact domains are Ocean''s own.'

x-pointers-omitted:
note: Deliberate absences, each measured on 2026-09-02. Recording them here so a later round does not re-litigate them,
and so no pointer asserts a surface Ocean does not serve.
omitted:
- type: WellKnown
reason: every named /.well-known/ path returns 404 on all three hosts; control probe also 404 (see well-known/)
- type: SecurityTxt
reason: /.well-known/security.txt 404 on oceanhealthsystems.com, www., and ckm.openehr.org
- type: MCPServer
reason: no first-party MCP server exists; mcp/ holds a DERIVED candidate with deployment.mode none
- type: AgentCard
reason: /.well-known/agent-card.json and /.well-known/agent.json 404 on every host; nothing written to a2a/
- type: SDKs
reason: no first-party client library in npm, PyPI, Maven Central or NuGet (see packages/)
- type: Idempotency
reason: no idempotency key; only conditional requests (if-match / if-unmodified-since, 412)
- type: StatusPage
reason: no status page; oceanhealthsystems.statuspage.io is Statuspage's catch-all, confirmed against a control probe
- type: Deprecation
reason: no deprecation or sunset policy, and zero operations marked deprecated in the contract
- type: Security
reason: no vulnerability disclosure policy, security.txt or bug bounty found
- type: Compliance
reason: no certifications or audit attestations published; no trust centre
- type: Pricing
reason: no pricing page anywhere in the site sitemap; every product routes to a demo form
- type: SignUp
reason: no self-serve sign-up; enterprise sales gate only
- type: Postman
reason: Postman public search returned zero collections or workspaces for CKM/openEHR
- type: AsyncAPI
reason: no event, streaming or webhook surface in the contract or the docs
- type: Webhooks
reason: no webhook catalogue published
- type: Protobuf
reason: no .proto published
- type: WSDL
reason: ?wsdl probes returned the HTML app shell or 410 Gone; no SOAP contract served
- type: OAuthScopes
reason: no oauth2 or openIdConnect scheme in the contract, so there is no scope surface
