Artifacts

Abstract base profile for one independently meaningful fact entered, selected, verified, or measured in a period-tracking application. Concrete facts may be day-scoped or timestamp-scoped at producer discretion; clients can group facts by local date for display.

Layer 0 required core fact: whether the source reports menstrual bleeding for the stated date or timestamp. Both true and false are meaningful only when explicitly recorded or reliably represented by the source.

Layer 1 optional intensity fact for an app's uncalibrated menstrual-flow category. This fact does not replace the Layer 0 menstrual bleeding boolean core fact.

Layer 1 optional symptom fact. The Observation code identifies the fact as a symptom report; the value identifies the specific symptom using an exact standard concept when available.

Layer 1 optional numeric pain fact for a source 0-10 patient-reported pain score. Use this profile only when the source stores a numeric 0-10 rating.

Layer 1 optional basal body temperature fact for a source temperature measurement identified by the producer as basal.

A self-contained FHIR R4 collection Bundle for transporting granular patient-generated period-tracking facts scoped to one person. It contains at least one Layer 0 menstrual bleeding fact. Patient and Device resources are optional.

Uncalibrated, patient-reported ordinal flow categories used by period-tracking applications.

A small, non-normative starter set of period-tracking symptoms that applications commonly record, offered so implementers can bootstrap a consistent symptom vocabulary. It includes SNOMED CT concepts where the fit is exact enough. It is NOT a closed or required binding: a fact's symptom value MAY use another SNOMED CT concept when the meaning is exact.

The eight provisional concepts required by this guide. These cover the Layer 0 bleeding core fact, the Layer 1 source-style ordinal menstrual-flow scale, and the generic Layer 1 symptom fact code.

A standalone Layer 1 basal body temperature fact from the longitudinal example.

A synthetic ~seven-cycle copper-IUD worked example built from the Layer 0 boolean bleeding core plus Layer 1 structured facts; this is the Bundle wrapped by the example SMART Health Link and rendered by the clinician viewer.
