Query Tools¶
AQL (Archetype Query Language) is the SQL equivalent for openEHR. Tooling for writing and testing AQL is thinner than for archetype authoring.
EHRbase REST API¶
| Owner and developers | EHRbase project, Vitasystems, and Peter L. Reichertz Institute |
| Available from | EHRbase sandbox |
The most common way to run AQL queries against EHRbase is directly through the REST API, using tools such as Postman, Insomnia, or curl. The sandbox includes an API explorer.
EHR Studio (Better)¶
| Status | Active - commercial |
| Cost | Commercial (part of Better Platform) |
| Owner and developer | Better |
| Available from | Better Studio registration |
What it is: Better's integrated development environment for its openEHR platform, including an AQL Builder with a graphical query-construction interface. It is not available as a standalone free tool.
AQL Builder for EHRbase (CRS4)¶
| Status | Active |
| Cost | Free |
| Open source | Yes |
| Owner and developer | CRS4 |
