OpenEHR Base package
0.1.0 - First Draft International flag

OpenEHR Base package, published by openEHR + HL7. This guide is not an authorized publication; it is the continuous build for version 0.1.0 built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/FHIR/openehr-base-ig/ and changes regularly. See the Directory of published versions

Logical Model: DV_DURATION

Official URL: http://openehr.org/fhir/StructureDefinition/DV_DURATION Version: 0.1.0
Standards status: Informative Maturity Level: 3 Computable Name: DV_DURATION

Represents a period of time with respect to a notional point in time, which is not specified. A sign may be used to indicate the duration is backwards in time rather than forwards.

NOTE: two deviations from ISO 8601 are supported, the first, to allow a negative sign, and the second allowing the 'W' designator to be mixed with other designators. See time types section in the Foundation Types model.

Used for recording the duration of something in the real world, particularly when there is a need a) to represent the duration in customary format, i.e. days, hours, minutes etc, and b) if it will be used in computational operations with date/time quantities, i.e. additions, subtractions etc.

Misuse: Durations cannot be used to represent points in time, or intervals of time.
