## Extension: ValidityPeriod Extension 

| | | |
| :--- | :--- | :--- |
| *Official URL*:http://hl7.org/fhir/uv/order-catalog/StructureDefinition/ValidityPeriod | *Version*:1.0.0 | |
| * Standards status: *[Trial-use](http://hl7.org/fhir/R5/versions.html#std-process) | [Maturity Level](http://hl7.org/fhir/versions.html#maturity): 2 | *Computable Name*:ValidityPeriod |
| *Other Identifiers:*OID:2.16.840.1.113883.4.642.40.55.42.27 | | |

The period [start date, end date] in which the Composition is valid (for Order Catalog profiles).

This extension uses the datatype Period, unlike the cqm-ValidityPeriod extension, created for Composition in 2014, which uses the datatype dateTime. Thus this extension enables to state a start date and/or an end date

**Context of Use**
