Prototype Limits

Limits

This prototype intentionally implements a focused subset.

• FHIR search supports the documented resource parameters and exact/ge/le date comparisons, not the complete FHIR search language.
• Patient _has support is limited to the documented patient-compartment resource/reference/search combinations.
• The Bulk Cohort API is experimental at FMM 1 in Bulk Data IG 4.0.0.
• Groups are runtime in-memory resources and are not a production cohort registry.
• Group creation runs in the background and reports completion or source errors through its async status Bundle. Bulk export files are computed during kickoff, although the external export contract uses the Bulk Data asynchronous pattern.
• _typeFilter supports the documented ordinary searches and is not a general cross-resource query language.
• _elements supports root elements only; mandatory fields are retained.
• Optional Bulk Data features not implemented by this server are rejected rather than silently ignored.
• The mock server is synthetic and not suitable for clinical use.
• Pseudonymization and minimization are demonstration controls, not a complete governance or authorization solution.
