Profile Rules

Overview

Profile rules ensure profiles are correctly defined with proper parent relationships and constraints.

Rules

`correctness/profile-parent-required`

Severity: Error Fixable: No

All profiles must specify a parent resource.

Example:

// ✓ Good
Profile: PatientProfile
Parent: Patient
* name 1..1

// ✗ Bad
Profile: PatientProfile
* name 1..1

`correctness/profile-constraint-strength`

Severity: Warning Fixable: No

Profile constraints should not weaken parent constraints.

Example:

// ✓ Good
Profile: PatientProfile
Parent: Patient
// Patient.name is 0..* in base, making it 1..1 is strengthening
* name 1..1

// ✗ Bad
Profile: StrictPatientProfile
Parent: PatientProfile  // PatientProfile has name 1..1
// Cannot weaken to 0..1
* name 0..1

`suspicious/profile-circular-parent`

Severity: Error Fixable: No

Profiles cannot have circular parent relationships.

Example:

// ✗ Bad - Circular dependency
Profile: ProfileA
Parent: ProfileB

Profile: ProfileB
Parent: ProfileA

Rationale

Proper profile validation ensures:

FHIR specification compliance
Valid constraint hierarchies
Prevents runtime validation errors
