EHRbase

EHRbase is an open source openEHR Clinical Data Repository (CDR) - a standards-based backend for storing, versioning and querying structured clinical data. It implements the official openEHR REST API (ITS-REST 1.0.2) against openEHR Reference Model 1.1.0, is queried with the Archetype Query Language (AQL), and adds Simplified Data Template projections (flat and structured JSON web templates) that make deeply nested openEHR compositions practical to write against. It is Apache-2.0 software each organization self-hosts - no vendor API host, no signup, no metering - maintained by vitagroup AG with the openEHR community, with a commercial distribution (HIP EHRbase) adding multi-tenancy, IHE ATNA audit logging, AQL event triggers, Saga-pattern transaction compensation and SLAs. A public credential-free sandbox at sandkiste.ehrbase.org serves its live OpenAPI 3.1.0 contract of 63 operations.

EHRbase publishes 3 APIs on the APIs.io network: openEHR REST API, Admin API, and Status and Metrics API. Tagged areas include Company, Healthcare, Health IT, Electronic Health Records, and Clinical Data.

The EHRbase catalog on APIs.io includes 1 event-driven AsyncAPI specification.

EHRbase’s developer surface includes documentation, API reference, getting-started guide, support, engineering blog, changelog, authentication, and 28 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/.

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 github.com/api-evangelist/ehrbase: open an issue to ask a question, or submit a pull request to add artifacts.
