Store secrets in FHIR resources without storing the values. Aidbox resolves them from vault-mounted files at runtime. Secure, dynamic, and no vendor lock-in.

StructureDefinition is a resource that describes the structure of other resources, including profiles, extensions, and data types.

Simplifier is a FHIR package registry that stores basic and custom FHIR packages.

The base FHIR specification outlines a set of fundamental resources utilized in various contexts within healthcare.

One key function of profiles is to modify the cardinality of an element. A profile can restrict an element's cardinality within its base structure.

In FHIR, you can define a profile not only for a resource but also for an extension.

The slicing mechanism enables the specification of requirements for array elements.

Binding is used to define an allowed set of values for an element.

Constraint - a validation rule that is defined on a profile and described using the FHIRPath syntax.

The FHIR specification includes many resources that describe various medical data. Sometimes, however, the basic resources are insufficient to describe the data, and in such cases, FHIR provides the following mechanisms for extending the basic resources.

FHIR IG (Implementation Guide) is a set of artifacts that describe the requirements for a FHIR server. For example, an IG may contain a set of rules, profiles, extensions, search parameters, and examples of FHIR resources.
