FHIR Resource Definition: Specifying Available Time Periods

Details

This page provides the specification definition (StructureDefinition) for an extension available as part of HL7 FHIR resources: 'ror-available-time-effective-opening-closing-date'. This structure contains two data types (`dateTime`): `start` (starting time) and `end` (ending time). By including these fields, it allows the explicit description of a temporal range during which medical information is valid. This is a critical technical element for attaching metadata regarding the resource's lifecycle or availability using FHIR extensions. The definition adheres to standard FHIR element constraints (e.g., all FHIR elements must have a `@value` or children) while enabling the incorporation of specific business logic—the temporal scope of validity—into the data model. In medical information systems, managing the reliability and expiration date of data is crucial, and this definition provides the technical foundation for doing so.
