# Interoperability

> MedLog maps onto W3C PROV, OpenTelemetry, and FHIR without requiring a new software stack.

Existing standards can represent MedLog's logging patterns without requiring a new software stack.

## W3C PROV

The W3C PROV model provides one framework for computational provenance, where MedLog records map to
`prov:Entity`, model invocations to `prov:Activity`, and users or models to `prov:Agent`.

| MedLog concept   | PROV concept    |
| ---------------- | --------------- |
| MedLog record    | `prov:Entity`   |
| Model invocation | `prov:Activity` |
| User or model    | `prov:Agent`    |

## OpenTelemetry

OpenTelemetry can collect and transport these events.

## FHIR

Fast Healthcare Interoperability Resources (FHIR) can anchor MedLog records to standardized clinical
entities such as **AuditEvent, Patient, Condition, Observation, Practitioner, and PractitionerRole**.
