CardinalKit

An open-source framework for the rapid development of modern, interoperable digital health applications.

For more information, please refer to the API documentation.

The CardinalKit Architecture

CardinalKit introduces a standards-based modular approach to building digital health applications. A standard builds the shared repository of data mapped to a common understanding that is used to exchange data between CardinalKit modules.

We differentiate between five different types of modules:

• Standard: Acts as a shared repository and common ground of communication between modules. We, e.g., provide the FHIR standard as a great standard to build your digital health applications.
• Data Sources: Provide input to a standard and utilize the standard's data source registration functionality and adapters to transform data into the standardized format. Examples include the HealthKit data source.
• Data Source User Interfaces: Data source user interfaces are data sources that also present user interface components. This, e.g., includes the questionnaire module in the CardinalKit Swift Package.
• Data Storage Providers: Data storage providers obtain elements from a standard and persistently store them. Examples include uploading the data to a cloud storage provider such as the Firebase module.
• Research Application User Interface: Research application user interfaces display additional context in the application and include the onboarding, consent, and contacts modules to display great digital health applications.

The API documentation includes a selector to switch between the different Swift Package Manager Targets, allowing you to explore the different modules that are included in the CardinalKit repository.

The CardinalKit Template Application

The CardinalKit Template Application provides a great starting point and example about using the different CardinalKit modules.
