Artifacts Summary

Contents:

This page provides a list of the FHIR artifacts defined as part of this implementation guide.

Structures: Logical Models

These define data models that represent the domain covered by this implementation guide in more business-friendly terms than the underlying FHIR resources.

Shareable View Definition

A profile for View Definitions intended to be shared between multiple systems. This requires that the View Definition have a defined URL and name. It also requires declaration of the FHIR version that the view is intended to be executed over, and the FHIR type of each column. This ensures consistent interpretation of the view across different view runner implementations.
Tabular View Definition

A profile for View Definitions where each resulting field must contain only a simple scalar value. This is sometimes referred to as 'CSV Mode', but applies to any system that explicitly constrains its views or tables to tabular data.
View Definition

A ViewDefinition represents a tabular projection of a FHIR resource, where the columns and inclusion criteria are defined by FHIRPath expressions.

Example: Example Instances

These are example instances that show what data produced and consumed by systems conforming with this implementation guide might look like.

PatientAddresses

An example of unnesting patient addresses into multiple rows.

This view uses forEach to indicate we are unrolling these into separate rows. The join function is used to create a single address line.
PatientAndContactAddressUnion

An example of unnesting patient addresses and contact addresss into multiple rows, which are unioned together into a single table.
PatientDemographics

A minimal example of a patient demographics view. This view uses the first 'official' patient name for our demographics table.
ShareablePatientDemographics

Creates the same view as the 'PatientDemographics' example, but applies both the ShareableViewDefinition and TabularViewDefinition profiles.
UsCoreBloodPressures

A simple view of blood pressure observations, with separate columns for systolic and diastolic values.
