Linkage on the FHIR specification website.
Identifies two or more records (resource instances) that refer to the same real-world "occurrence".
The body should be a list of valid JSON patches for Linkage. For example, to update a Slot status to busy, this would be the body:
[
{
op: 'replace',
path: '/status',
value: 'busy',
},
],
