## Logical Model: Feature Definition

Official URL: http://hl7.org/fhir/uv/application-feature/StructureDefinition/FeatureDefinition | Version: 1.0.0
Standards status: Trial-use | Maturity Level: 2 | Computable Name: FeatureDefinition

A definition of a feature that applications may implement, or be required to implement. Features are an aspect of a an applications implementation that generally impacts on the handling of data received from or provided to from the application, which makes it worth declaring. Once declared,

Usages:

- Refer to this Logical Model: Feature Query Input Parameters, Feature Query Output Parameters and Feature
