The name matches the "Adapters for non-FHIR server Connectivity" product line. note: Single release, 2017-06-21. Oldest and least-downloaded of the three. findings: - >- All three first-party packages are .NET-only. There is no JavaScript, Python, Java or Go client for a FHIR API whose buyers are health-IT developers. - >- Newest first-party release is 2019-03-04. The certified R4 API dates from 2022-06-29 and the MCP server product was announced later still; no package has been touched since. This is the strongest provider-published decay signal on the Carefluence surface. - >- None of the three packages publishes a repository URL, licence URL or release notes, so a consumer cannot see what changed or read the source.
