## Logical Model: Observation Period OMOP Table 

| | |
| :--- | :--- |
| *Official URL*:https://interop.aphp.fr/ig/fhir/dm/StructureDefinition/OMOPObservationPeriod | *Version*:0.1.0 |
| Draft as of 2025-10-23 | *Computable Name*:OMOPObservationPeriod |

 
This table contains records which define spans of time during which two conditions are expected to hold: (i) Clinical Events that happened to the Person are recorded in the Event tables, and (ii) absense of records indicate such Events did not occur during this span of time. 

**Usages:**

* This Logical Model is not used by any profiles in this Implementation Guide
