The date is often not tracked until the resource is published, but may be present on draft content. Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the ObservationDefinition. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

               value="Element `ObservationDefinition.status` has a context of ObservationDefinition based on following the parent source element upwards and mapping to `ObservationDefinition`.
Element `ObservationDefinition.status` has no mapping targets in FHIR R4B. Typically, this is because the element has been added (is a new element).
An externally-defined extension that has been mapped as the representation of FHIR R5 element `ObservationDefinition.status`: `http://hl7.org/fhir/StructureDefinition/artifact-status`.
A nominal state-transition diagram can be found in the [Definition pattern](https://hl7.org/fhir/definition.ht.html#statemachine) documentation
Unknown does not represent &quot;other&quot; - one of the defined statuses must apply. Unknown is used when the authoring system is not sure what the current status is.

This is used when there is no way to reference the other resource directly, either because the entity it represents is not available through a FHIR server, or because there is no way for the author of the resource to convert a known identifier to an actual location. There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference."/>
      <comment
               value="When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. 

When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference

Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference.  For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport).  One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any)."/>

There is no requirement that a Reference.identifier point to something that is actually exposed as a FHIR instance, but it SHALL point to a business concept that would be expected to be exposed as a FHIR instance, and that instance would need to be of a FHIR resource type allowed by the reference."/>
      <comment
               value="When an identifier is provided in place of a reference, any system processing the reference will only be able to resolve the identifier to a reference if it understands the business context in which the identifier is used. Sometimes this is global (e.g. a national identifier) but often it is not. For this reason, none of the useful mechanisms described for working with references (e.g. chaining, includes) are possible, nor should servers be expected to be able resolve the reference. Servers may accept an identifier based reference untouched, resolve it, and/or reject it - see CapabilityStatement.rest.resource.referencePolicy. 

When both an identifier and a literal reference are provided, the literal reference is preferred. Applications processing the resource are allowed - but not required - to check that the identifier matches the literal reference

Applications converting a logical reference to a literal reference may choose to leave the logical reference present, or remove it.

Reference is intended to point to a structure that can potentially be expressed as a FHIR resource, though there is no need for it to exist as an actual FHIR resource instance - except in as much as an application wishes to actual find the target of the reference. The content referred to be the identifier must meet the logical constraints implied by any limitations on what resource types are permitted for the reference.  For example, it would not be legitimate to send the identifier for a drug prescription if the type were Reference(Observation|DiagnosticReport).  One of the use-cases for Reference.identifier is the situation where no FHIR representation exists (where the type is Reference (Any)."/>

An externally-defined extension that has been mapped as the representation of FHIR R5 element `ObservationDefinition.date`: `http://hl7.org/fhir/StructureDefinition/artifact-date`.
The date is often not tracked until the resource is published, but may be present on draft content. Note that this is not the same as the resource last-modified-date, since the resource may be a secondary representation of the ObservationDefinition. Additional specific dates may be added as extensions or be found by consulting Provenances associated with past versions of the resource.

An externally-defined extension that has been mapped as the representation of FHIR R5 element `ObservationDefinition.status`: `http://hl7.org/fhir/StructureDefinition/artifact-status`.
A nominal state-transition diagram can be found in the [Definition pattern](https://hl7.org/fhir/definition.ht.html#statemachine) documentation
Unknown does not represent &quot;other&quot; - one of the defined statuses must apply. Unknown is used when the authoring system is not sure what the current status is.
